For you guys who already have the xoom please chime in.
I have a IPAD (dont judge me lol) and the "GPS" does not work while airborne; this is a big deal for me as i am a pilot.
Does the xoom gps only work when in cellphone range like the ipad or does it have a no kidding GPS chip?
On a side not i have no clue how apple gets away with selling the ipad as having GPS when it clearly is not TRUE GPS.
Since the wifi version will contain GPS as well, my guess is that it should work. I'll let you know once I get it in hand today.
When you look up on the Motorola website it states "aGPS" which is assisted GPS. IMO this means it uses regular GPS and other signals in addition. How that translates to airborne IDK. But surely the XOOM shouldn't be used for airplane navigation There's probably an iPad app for that ROFL

Xoom has the same gps. The chip works fine for following without a cell/wifi connection. To get actually directions you have to have a connection.

its got its own gps chip. and it locks on instantly. and i mean instant. accurate to 4 meters according to google maps.
the only problem you would run into are the maps.
you would need the maps saved on the xoom. google maps can and does cache maps while on wifi, but if you deviate off the set path during the trip you won't be able to load any additional maps during the trip unless you can get a wifi or data connection.
so you would need a gps app that stores the maps on the device if you want it to function like a standard gps. i know there are some for the iphone, but i haven't looked into android 3rd party gps apps.
I think it depends on what you want to use it for. If you want google maps, then the maps program requires data use to show your location on the map. If you simply want Longitude and Latitude, then I'm sure you can get that with the GPS chip in the Xoom.
I've got the Xoom, and the GPS is a true GPS, not relying on cell towers or wifi to determine location. However, I don't know how well GPS works in a plane since I've never tried using a GPS device in a plane (I thought that wasn't allowed?)
Again, unless you have maps STORED on your device, data access is needed to download the maps in real time. Applications like TomTom store the maps on your device, but require an additional and substantial fee.

so what can you do with the gps chip with no connection?
is there anway to save a preloaded map and use your gps chip to locate yourself on the previously saved map?
EDIT: So then theoretically I can dev an app that will have maps saved on the phone for use with no signal?
You should be able to get an app that gives you the GPS coordinates. Everything else is based of stored data, like others mentioned.

Uhmm, theoretically sure, but good luck getting the maps you're going to need, and starting from scratch would be hella painful. You would be better off purchasing a stand alone application with the maps. They usually run around $100, but I'm not sure what ones are available for Android.
They aren't normal maps, they're maps that contain location data, gps coordinates, etc.
Again, you can use a GPS app to pull your coordinates. Just do that and use a paper map to determine where you are? hehe

You really want to know why you can't use the GPS (of your mobile device) while you're flying?
You're not a commercial pilot I hope!
I'm sorry I'm just having a hard time picturing my Continental Airlines pilot asking for directions from texas to california because he forgot his Ipad at home.
I know the app AlpineQuest uses maps that you yourself create from a list of already available maps and then you load them onto your device and select them from the application. Its primarily for hiking since some terrain does not offer a 3g signal. But I recommend you check that out.
Does you tried IGO ???
(propably no plane support )
Thanx
ok got my answer thank you!
Also the GPS on a device will not interfere with any aircraft electronics and is 100% ok during flight. AKA when not flying and riding along everyday for 4+ hours with nothing to do.

Actually I am a FAA certified Commercial pilot, i have a degree from Embry-Riddle in Professional Aeronautics with dual minors in safety and business, over 275 combat hours alone just here in Afghanistan, so no that does not automatically mean you fly for the airlines.
Also you cannot use an unapproved system for your primary means of navigation. The only GPS you may use is an IFR approved unit with a current database. Also if you choose to go that route you must have a backup (VOR, NDB, etc).
See:

(just needs to be android not ipad)
The reason i ask is because when im not flying aka in the back aka a passenger, im bored and would like to be able to see where i am at on a map.
But thank you for contributing nothing to this post other than to launch a personnel attack against my creditability.
Rant over:
To everyone else who actually contributed to the post THANK YOU! I will try probably all of those apps lol. I just wish there was a FalconView port for android (open source DoD app designed for windows).
may it's out of civilian range, see en.wikipedia.org/wiki/Global_Positioning_System#Restrictions_on_civilian_use
Hi pyrator,
I too am a pilot (mind you, not FAA but on the other side of the pond) and I'm also very interested in using Android tabs for aviation.
Of course not IFR, but as a backup information in VFR should the Garmin fail (never did so far)
It would be very interesting to find out what the real capabilities of the onboard sensors are.
Take the gyro for example: if it doesn't drift, it might be an interesting source for a poor man's EADI (attitude indicator) should your vacuum pump quit. It all depends if it is influenced by accelerated flight (I've looked at a few apps that wanted to simulate an AI but they relied on the accelerometers and, in a coordinated turn, you got zilch)
I'm a programmer so I guess writing an application would be an option, but its much more fun if you're not alone....
What do you think?
GPS in the Xoom is standalone. It works with wifi and 3g off. I installed copilot and it works as well as all the tomtoms and garmins that I have used. U get a beautiful 10 inch gps.
Agps is based on cellular signals.

1. Non-commercial VFR (in the US) you can use anything you want. You don't even need a chart. If you have a chart, it must be current. This may apply to map data.
2. The prohibition against using Cell Phones, etc while flying (in the US) is not a FAA rule but a FCC rule. If your 3G unit is transmitting from a high altitude the Cell(s) on the ground have a hard time figuring out which cell you're in.
3. As a Pax aloft, put the Xoom in airplane mode (turns off the 3G) after you've loaded up map data for your intended area and (fuselage skin notwithstanding) you should be able to follow along just fine. Keeping the unit near a window may be necessary.
GPS in my xoom does not work without wifi.
I have read the threads and I am unable to make it work without wifi like driving. I have the maps incache, but the GPS signal does not show. The ipad does because I have use it multiple times. What to do. Many hours wasted.

New to the forums, and betting this is a stupid Question, but I was wondering if there was anyway to tap into the GPS locater(built in for emergency calls such as 911) and use that for a GPS application, If the Wizard even has one built in, I would imagine that it does, but anways wondering if its possible, and if anyone has any incite into how to use this/turn it on?
There's no GPS in the wizard.

Emergency services can locate your phone fairly accurately using triangulation from the gsm phone masts, using network data. There was a company selling a tracking service such as this for mobile users a while back, but I forget the details.
yeah ran into that service a while back, but the main way to get to it was to buy two handsets and pay for their cheap data service and put the other handset in someones car or whatever and use the 1st handset to track them...
I think that navizon.com has a program like that. theres a trial version for free. Doesnt google maps also use that technology?
hmm try google map 2.0 they show u wat ur location is without GPS
try http://forum.xda-developers.com/showthread.php?t=349188
I've tried both of these apps and both aren't worth a crap to me. They get my location in the right state, heck even the right city...almost. But I can't get it to be consistent let alone even half right.
I tried em both out and would like to know what I have been doing wrong since everyone else says that they are "great."
Thanks,

It's already been said, but get Google Map 2.0...I installed it a few days ago, and it's not bad. I'm usually within 2000ft. of the calculated location.

The only thing you did wrong was expect triangulation to work like you're watching CSI. In the real world, there is signal bounce, interference from trees, buildings, and other radio transmissions, and a whole host of other nameless error-creating problems. Radio triangulation is severely limited, but considering this sort of feature wasn't even available as a free application (much less being built into a mapping software as robust as GMaps) until VERY recently, it's pretty good, if you don't have GPS. You can buy a dongle to attach to your MDA, or you can suck it up, and deal with generally inaccurate location.
Trying it again...I thought that I had 2.0 but maybe not...I'll let you know either way how it comes out this time.

Ok much better...however it is still like 4 miles!!! off.
Does it update when in travel or how/when will it become more accurate??
Thanks agian,

Google Maps 2 has "My location"
I dunno if you knew but Google Maps has been updated now and it offers My location - which is pretty close what GPS does. It gets your position through cellular towers and then it locates you within half a mile if I'm not mistaken...
Try it and c if it works 4 u

Actually google maps DOES NOT use triangulation..it will just show ur position based on a single cell tower and the signal strength being calculated by your phone..
So I tried my Google Maps 2.0 on the fly today...
It told me that it wouldn't work because I did not have a "data connection" and that I needed to contact my "service provider" to be able to utilize that function... (Or some crap like that)
What am I doing wrong now??

I'm trying to develope an application for my Trinity, and I'm currently thinking of implementing a GPS function to track down my current position.
But: I've heard there also are other metods to find out your position, by triangling the GSM-bases, using GPRS-position(???) and also, I've seen a service that uses SMS(??? It says you can send a SMS to a server, and it will find out where you are...=)
Now, which one of these are pure misunderstandings, and which one does work?
I've heard of a application that that uses GSM-bases to triangling the position, and it actually works...
So my second part is, anyone knows how to implement this is C# ?
It can be done...

I can't help you on how to do it, but I know an app that does. Google Maps works this way. It finds my location within about 1Km using GPRS. I don't have GSP on my phone. It only works is some locations. For example, at my house (in a rural area) it doesn't work. I am guessing this is either because I have only one base providing service, or that base is missing certain features.
Good luck on finding a solution to implement this. It can be done somehow.

Great, that means that there is actually something called GPRS-positioning, now the 10 billion dollar question is how to implement this
Yes, the Google Maps "location" feature works well for me in USA. It locates the nearest cel towers to my device...good luck with your project.
i don't know about GPRS-positioning, but i do know for sure that Google Maps doesn't use it like PhilD41 said, Google Maps tries to figure out your location using cell phone towers around you. Cell Tower Triangulation, i think is the term. you can search that term and see how to implement it

Hi! Thanks for the reply, I belive this is something else then assisted GPS... Since the A-GPS, as you said needs a A-GPS server on the operator-side, while triangulation only needs three cell towers.... (Less accuracy, but still)

This is the kind of feature I want to implement, but I need to find out how to do this in coding...
Hi,
some interesting for you i hope.
As far as I can work out GoogleMaps uses the navizon database to triangulate your position. Navizon uses freely donates gps+wifi data.
Here's my slightly informed opinion, from best to worst
connected/Inbuilt GPS: most accurate u will get
Navizon: probably as good as AGPS but i think better as it triangulates on phone mast details and (if u have wifi built in) wifi router details (see website for this cool feature)
A-GPS: next most accurate you will get.
No such thing as SMS/GPRS location. This is in fact a service provided by companies who use a mobile phone operators databases to triangulate your position (API licenses cost between £500 and £2000 in UK PER operator!!!) . So not much better than AGPS but a method (with a cost).
Can you do this in c#? yes. download Visual Studio 2008 90-day trial edition and you'll find a GPS application ready and waiting. Its a bit buggy but a g8 starting point.
If you simply want to get gps position for an app without having to code anything, you might want to wait a little and download my next GPSSpot application. It will save the current GPS position to a registry key for other apps to use.

Wow! Nice reply sir!
But this really starts to stirr around my noodles - since I have a Iphone here, without a GPS, and it can give me a +- 100/200 m accuracy on where I'm using cell tower triangulation...
When it comes to the GPS-part, I've coded it finished, so I'm just so curious on how the author has done it... Is it using some sort of cell-tower location database? Hmm... I've tried to mail the developer, but without luck
But, when it comes to my app, I think NaviZone is the way to go...
if iPhone has wifi (which i believe it does) Navizone is the way forward. It will consume more power as your wifi has to be on. But it will only work in areas that have been "surveyed" by donating users.
(btw its also good to find local free hot-spots/unblocked wifi routers)
btw, cell-tower location databases have a VERY wide range in accuracy. Firstly its dependent on the accuracy of the cell knowing its own GPS position (big discussion came to my mind on how interesting that is, but I'll leave this out for now). Then dependent on the number of cells used in the calculation (the more cells the better.) So, inner city regions get fair to good accuracy, but out in the country accuracy drops to >1000m radius.
I'd be interested to know what the iPhone is like for accuracy out in the sticks, and whether they use NaviZone or a similar service.
The other day the GPS had the weirdest issue. I was stuck in traffic and decided to turn on Google Maps to find out how long the traffic is going to be. To my disbelief, the GPS showed me in a different town and MOVING on the street and then onto some freeway about 50 miles from my location. I thought the GPS satellites are screwed up but my car was showing me in the right place (and never has made such a stupid error).
Makes me wonder if the GPS info is actually going to Google servers and coming back to the phone as I guess I was getting someone else's GPS data and the lines were crossed somehow. This continued to about 30 minutes as I was enjoying the error and wondering at the same time. Holding the phone out of the window and stuff did not work. Eventually I reboot (oops! I meant I took the battery out because HTC apparently thinks we never need to reboot te G1 so there is no PIN hole for reboot like most other phones).
has anyone else experienced the same issue?

The GPS is not being relayed to google... but google maps may be the thing that is wrong here. You can't get your "lines crossed" when using google maps but the maps may be downloading the wrong set. I know I have seen it do some weird things but that is expected to happen when you have several countries you have to have maps for.
As for the reboot issue... is it really that hard to hold down the power button? You do realize that the pin hole on previous devices is for emergencies only. It could really screw up the phone. Similarly like using your computer and unpluging it while it is on... or just pressing its reset button.
Maybe this is the reason for your problems with your G1.
I was just browsing my location and found that the location was in my local Radio Shack that was 2 blocks away. I tried to refresh but wouldn't allow me to.
G1 uses assisted GPS, which performs some calculations away from your phone. Could have been your A-GPS server was sending back some faulty data.
Some Application in G1 read Location info from Proprietary GPS Chip and also relies on Cell Tower GPS Coordination if GPS Signals is not available, in India my Airtel Company have Bad GPS Coordination in my Cell Tower, I Personally know which Cell Tower i am hooked to while i am at home but the Cell GPS Coordination is 8 Miles away from my Cell Tower.
Check that your GPS Signal were Strong and you have not just started seeing maps when that error occured.
I think it was stong. I had all my bars full and the 3g logo on it. Oh well I'll probably fiddle with it a little more tomorrow after I try to get a screen protector for the phone
I thought the problem had gone away until last night it happened again, with one difference. I still had me being shown 20-30 miles away (interestingly not across the globe but simply 30 miles away) the problem corrected itself after about 5 minutes.
I have a car GPS and a portable GPS and I have never seen this happen before. The issue is definately the A-GPS. I always thought during WAR the military may scramble the GPS data to confuse the enemy, I guess that is what promted Europeans to install their own GPS that is much more accurate than ours.
And there are controversies over this as well. Google is recording my location and my cell towers and IP addresses and URLs according to its NO privacy policy. This is definitely not fun.
Sending my GPS info to Google servers (which is in fact the case) without me knowing it and sending it back to my phone through internet channels it not something I am comfortable with. Especially if Google releases information to law enforcement one day that may be incorrect showing me somewhere I really was not at!

same problem here. i also think it started with the update.
Guys, I am not wrong.
A-GPS as Google calls it (and there are other versions of it), is for phones without a GPS chip (thats how Google Maps find you on a T-Mobile WING), it started after an fcc mandate to be able to locate 911 callers from cell phone. It finds your location using a triangulation of the cell towers you are connected to and this particular technology and the extensive data that is required is owned by Google however Google may not call it AGPS.
http://www.techcrunch.com/2007/11/28/google-mobile-maps-pinpoints-your-location-without-gps/
Now it seems to me that Google is enhancing its data network of cell towers using our phones to collect location data. So it collects the cell towers we are connected to with the strength+ the GPS info from our phones and puts all this data in a server to that non-GPS phones using Google Maps can have a better triangulation as more data is gathered from across the country. Eventually the system could be perfected to locate any cell phone without a GPS chip or to locate a cellphone with the GPS feature turned off for privacy, and that is what concerns me.
When my phone shows me 20 miles from where I am, on the freeway, cruising at 55MPH while I am sitting in traffic on the other side of town, it concerns me.

Where are you getting your information? The link you provide just says they support phones without GPS but they never say it is only for phones without GPS. In fact it says that it will work on phones with GPS... that is what the whole article is about that phones in the future will have GPS and google maps will be able to pinpoint their location faster. Basically it says they are using A-GPS.
In the link above he links to http://www.techcrunch.com/2007/11/28/google-earth-heading-towards-extinction/ Which says people will be able to add their own commentary about places like a wiki. Nothing about using other peoples devices to send information for google to collect.
It also has this link http://www.google.com/intl/en/press/annc/20071128_maps_mobile_my_location.html Which is googles official press link saying it will work with both GPS and non-GPS phones by using the Cell ID and a special formula that google developed to pinpoint your location within a certain amount of distance. Nothing says it uses other peoples GPS signals. In fact it says "This approximation is anonymous, as Google does not gather any personally identifiable information or associate any location data with personally identifiable information as part of the My Location feature."

Where are you getting your information? The link you provide just says they support phones without GPS but they never say it is only for phones without GPS. In fact it says that it will work on phones with GPS... that is what the whole article is about that phones in the future will have GPS and google maps will be able to pinpoint their location faster. Basically it says they are using A-GPS.
In the link above he links to http://www.techcrunch.com/2007/11/28/google-earth-heading-towards-extinction/ Which says people will be able to add their own commentary about places like a wiki. Nothing about using other peoples devices to send information for google to collect.
It also has this link http://www.google.com/intl/en/press/annc/20071128_maps_mobile_my_location.html Which is googles official press link saying it will work with both GPS and non-GPS phones by using the Cell ID and a special formula that google developed to pinpoint your location within a certain amount of distance. Nothing says it uses other peoples GPS signals. In fact it says "This approximation is anonymous, as Google does not gather any personally identifiable information or associate any location data with personally identifiable information as part of the My Location feature."
All in all I think you are misreading and need to look over your data again.

Regardless of above, and you may be correct and I may be wrong, but the thread is getting distracted from the main subject. My main issue is this: Why is the GPS reporting me in the wrong location, and even MOVING which is weird. It was pretty obvious to me from what I saw that the Google Maps software in my phone was reading someone else's location data from someone else's GPS. I could see the person move through the streets and speed up and slow down. This makes me wonder if my locatio data is being sent to Google servers somewhere and then back to the phone (and in some cases crossed over with another persons data). This feels especially more true because Google MAPS has slowed down dramatically from finding "My Location" compared to "pre RC30" upgrade and even compared to the GPS-Chop-Free WING and even my ancient car's GPS system.
Have you talked to Google about this? I think you are just speculating what you want and have a hidden agenda. Did it locate you within so many feet? or was it a real location? If it was a real location than it couldn't be Google as it only pulls the map the actual lat, long is coming straight from the sats... possibly it pulled the wrong location for that tower while using A-GPS and then this calculated the wrong GPS coordinates.
Since you don't know what or how A-GPS works this may be hard to understand. A-GPS works by using that method you described for non-GPS cellphones to narrow the search for satalites. This doesn't find your location it only finds the vicinity. You can see the A part of A-GPS work when it says your location within so many meters. This is what works on your wing. The actual pinpoint location is based only off the GPS and isn't sent to google. Google only needs the map coordinates to download. Your GPS is what tracks you on the map. This is why google maps always load in blocks.
To fully understand a map system you must learn how maps work and be educated in the art of cairegraphy
I think the real concern is that brooklynite was seeing himself moving through traffic while he was actually stationary. I can understand that perhaps the GPS got the wrong co-ords and the incorrect map was loaded showing him in another location, but you would still expect him to be shown stationary in the wrong location. So why would it show him moving when he was stationary?
The fact that he was moving on the map means the data must have been coming from another device doesn't it? How else could you explain it?
I would be concerned too.

A real location about 50 miles away from my location. Somewhere I have never been since I have had this phone so it cannot be using the old data in my phone as sometimes it shows my locations from "last night".

I always have the "use wireless networks" off, afterall, the GPS chip is one of the main reasons I switched to the G1 from my older WING.
....
I have to add that I am amazed by the GPS accuracy, it even notices when I cross the stree, turn into a driveway or the side of the street I am standing on. When I switch to Sat. view, it literally shows my exact spot on the sidewalk, not in the middle of the street like a car GPS does.
Probably getting too far off topic but car GPS units are just as accurate, it's just that most of them have a correction feature to fudge your position onto the nearest road on the map if for some reason it is not. For the most part a driver doesn't care where he is on the road in relation to the curb....only that he is on the road he thinks he should be on.

"EDIT" UPDATE (7 oct. 2010)
Well you dont need to go actually much further then this first post!
Things got out of context over here, furthermore I decided to give
my external gps receiver a break and run some more tests with
the internal one of my SGS.
And the results I got were much better than any
other phone I tested before. Except the ones with a build-in SirfstarIII chipset.
If you have Gps issues,Just move on to this thread:
2nd edit (20 Oct, 2010): That thread was removed without any warning or explanation so I posted the videos in another thread:

RCinFLA said:
Like to share my experience as cellphone chipset designer and my dealing with various parties involved with GPS in phones.
Many of the issues are caused by business interests involved and there are quite a few parties plying to control location based services revenue stream.
SUPL, secure user plane protocol AGPS was created by network operators interest in mine, with the objective of putting them in the controlling position when it comes to extracting revenue from location based applications on their network.
Control plane AGPS is a general system where network operator independent entities can create a assist server along with possible services offering. They can encrypt their access to allow only subcribed (paying) users to access their service. The network operators has little control over this scheme.
With SUPL, in most cases, network operators outsource the location server function. Network operator hold location of their cell tower, as a total database, in close confidence. The network tower locations are also very dynamic over time. I believe the AGPS contractors don't get reliable and timely updates from the network operators.
Then there are third party business like 'Skyhook' which is trying to work around the network operator roadblocks by establishing a 'ponzi scheme' server database. If your phone has a good GPS location lock and detects a WiFi network, Skyhook's background app will have your phone send a message to their server reporting the SSID of the WiFi and its location. They then sell their server AGPS service to other companies, like Motorola, for inclusion in their phone software. Motorola may run into conflict with network operators. A network operator might refuse to buy a Motorola phone model with Skyhook installed on it. I noticed from the Captivate forum that the ATT version of Galaxy S has Skyhook capability.
Google is the 900 pound gorilla and is trying to wrestle control of location based services from network operators.
Finally there are the GPS chip manufacturers. Almost all of them have an AGPS server scheme of their own and try to promote it. The frontend processing (up to recovery of raw 50 bps satellite data) has unique hardware and firmware that are considered proprietary by the GPS chip manufacturer. In most cases a phone manufacturers like Samsung or Motorola are not allowed to have the software source code for this firmware or information on the actual interface protocol to the GPS chip. They are given a bundled binary file that the phone manufacturer software just dumps to the GPS chip at startup.
It is now up to the phone manufacturer to implement the GPS chip and antenna systems (along with WiFI, Bluetooth, Near Field Comm, and multi-band cellular) and provide software interfaces and drivers necessary to run the GPS function.
For size and cost reasons most recent GPS chips rely on the main application processor within the phone to actually do the GPS fix calculations. The software for this is provided by the GPS chip supplier but it must be coordinated with the particular applications processor chip used by the phone. It must share processing time slicing with the apps processor and work with operating system software resources such as RAM and ROM management running on the phone.
This is the first obsticle as most of the GPS chip suppliers have little expertise in the OS's that may be used (like Android or Symbian). The phone manufacturer usually has to provide help to create and debug the GPS driver software but the drivers are responsible/owned by the GPS chip supplier. There can be unique hardware/software interfaces that must be dealt with, like providing GPS TCXO calibration and cellular corrected frequency timebase to the GPS chip.
Then there is the OS's GPS interface. There can be translation software layers involved here. One such interface is based on GPS NMEA protocol but with additional hooks for things unique to phone operation like battery saver power strobing, and the complicated Secure User Plane or Control plane interface.
The AGPS system design landscape is litered with intellectual properties (patents) by many parties. Qualcomm is a dominate player here since their aquistion of SnapTrak company years ago. Royalties are paid to Qualcomm for every WCDMA phone sold, not only in AGPS area, but on basic CDMA patents used in a UMTS (Wideband CDMA) phones.
Now as to Samsung Galaxy S implementation of Broadcom GPS.
I think there is a lot of evidence that Samsung had early issues with the GPS antenna contact hardware. This has probably been corrected on recently manufactured phones.
I think the firmware supplied by Broadcom has the bandwidth of the correlators tighted down to provide greater sensitivity. This is great as long as there is a very good AGPS system to provide initial satellite ephemeris data. Without a good AGPS network providing satellite information the initial search and lock can take a very long time with narrow bandwidth frequency bins.
I have not seen evidence with my experience that my two Vibrants are receiving any reliable AGPS information from the T-Mobile network. They do seem to get rough Almanac satellite info from Google or other third party apps. These may be based on WiFi detection more then T-Mobile cell tower locations.
In LBStest I noticed that GPS Operational Mode has been set to 'Standalone'. I interpret this to mean AGPS is deactived. I don't see any difference when I switch to MS based assist, and clear the GPS saved memory to prevent it from prejudicing time to first fix lock test. Switching SUPL server to supl.google.com and port 7276 (with MS based operational setting) just seems to make my phone lockup for short periods of time.
Once phone does get full lock on satellites its performance is quite good. (my two Vibrant's were purchased in early Feb 2011). It rivals my Garmin SiRFstar III based GPS unit in locked on sensitivity while inside a building.
I think the AGPS system issues will get worked out over time.
The Qualcomm based CDMA2000 systems (like Verizon) will likely have better initial coordination on AGPS system operation. CDMA2000 also provides network timebase directly compatible with GPS.

All this nagging about GPS.....that it is not working in many devices and it's working in other many.....and of course I am talking about those ones who still would go for ONLINE gps navigation.....
In my humble opinion, what you guys should be asking yourselfs and the big corporations is, why nowadays, 99% of the smartphones(so not just sgs), even the most expensive ones are build with weak, less capable internal gps receivers, forcing users to go online(celular network /a-gps) or using external bluetooth gps receivers to get stable satellite fixes that means stable navigation.
Years ago, many of the first smartphones came with sirfstar chipsets or alike , so once again, why not now? That's the question that should not be ignored or forgotten.
A friend of mine, that would not dare to pay more than a 100 box for a phone, bought an ancient ETEN device on a sale for 40 box with that old windows mobile 5 and guess what...the internal gps get fast fixes just like any standalone gps device because it got the same sirfstarIII chipset
Why the heck, the expensive so called high-end smartphones of today are not build with better gps chipsets? Why A-gps? So we are forced to get data accounts?
And what happens when I want to navigate abroad? Roaming?
For data transfer and internet I use wifi; I have it at home and I find hotspots everywhere...I will save those extra 120 euros(or more) per year (data account costs)
And nobody will force me to get one(internet/data account); not even for gps navigation that I so much use..
I use gps navigation only offline, using a external bluetooth device on a daily basis and, many times abroad; it works like a charm on my SGS; and I am talking about serious GPS car navigation software like iGo, Sygic, Navigon etc. .
Don't even use Google maps or alike.
I cannot tell you how my sgs is doing on online navigation, I dont have a data account so I wont even try it.
But once Samsung get this online gps navigation thing fixed, you guys should concentrate your energy on the real issue:
The A-gps scam
And for all the corporations out there: Just deliver a device with a capable gps chipset and you will sell millions..
And for all the users out there: Just get a good compact external bluetooth gps receiver and stop nagging....
Thanks to 3rd party developers, the Android OS on my SGS can be "fooled" and I can connect any navigation software to my bluetooth gps receiver threw programs like Bluetooth Gps Mouse Unlimited and Gps Provider.
I do have to " allow mock locations" at settings first...

¿Ein? You don need data to get GPS fix, A-GPS is only an aid to get faster fixes
I thtink you're a littel misinformed
LOL.. o boy.. the AGPS is to help say if your indoors so you can get a faster lock... the phone will work without it.
Ummm I can see why you would think what you think, but I do believe you are wrong.
Firstly: as far as I'm aware, the SGS has the same GPS chip as the latest TomTom standalone unit.
Secondly: I guess AGPS is a data feature, it uses the triangulation of cell towers and pulls information to assist a sat lock, but it is not really a different way of using GPS. Ultimately you still need to get a sat lock to use a GPS App.
So it may speed up this lock, but it won't replace it. It just means it'll take you a little longer to get a sat lock than without it.
So you have the choice use it or don;t use it, no-one is forcing you to use data.

No, you're missing the point, you don't need any kind of data connection to use GPS, you can use it offline
Exactly...already the first line of Wikipedia says it: "Assisted GPS, generally abbreviated as A-GPS, is a system which can improve the startup performance of a GPS satellite-based positioning system."
There is, however, a related issue w/r/t A-GPS and a data account. Back on WinMo, I could download the ephemeris data to speed up the GPS fix for one week in advance (I think it was called QuickGPS or something on my HTC TouchHD, also had sth. like it on an old Eten). This allowed you to get a quick fix for said week, even without a data connection. Android, on the other hand, seems to download this data on the fly - meaning that if you don't have a data account you will experience a slow fix until your almanac has been filled "naturally" by the satellites you're seeing. I experienced that while on vacation this year without a roaming data contract - it took me a good 3-5 minutes to get the first fix and it was good from there on (well, as good as the SGS GPS gets ). I'd love to have some tool that does exactly what QuickGPS did, but I am not aware of anything like it.

seems you all are little misinformed as to how the gps on android specifically sgs works. It is actually three systems at work here. Gps standalone without gprs and cell triangulation which gets lock within a minute same as standalone bluetooth units (they also take up to a minute from cold boot but because generally it is plugged in the car lighter and always on people think its blazing fast).then you have agps that downloads preloads data regarding satellite location in regards to your position via network instead of downloading same data directly from satellite thereby saving time. Both these can be used without checking network location in settings so to recap if your network location is unchecked you are still using agps as long as you have network connection (data connection that is).and samsungs system for agps being better than others cause it downloads data for while week as opposed to others downloading data everyone gps is turned on. Third level is network triangulation via cell towers that gets you that instant lock at the cost of accuracy useful mainly to let apps get your general location without having to engage real gps thereby saving power as well as give maps a chance to start calculating route while gps is still getting lock therefore appearing to operate faster.

Standalone gps's got their batterys, and thus they start "warm".
Thing is, standalone SRIF3/4 gps gets a warm lock without any AGPS nor network triangulation within 5-10 seconds. SGS (and bunch of top-of-the pack devices) cant come even close to that.
the GPS on the SGS works fine offline
i don't even have data on when going on long road trips
you just need an offline GPS software with maps, like CoPilot or some other one you like

Sure they do. Sgs warm lock is 5 to 10 seconds as well. To test get the lock first then turn of data and network lock then start gps.restart of the phone same as restart of the standalone counts as a cold boot and takes about minute.

Here ya go.... I don't have to prove anything just look on youtube.. This is the phone on for just 10sec.. if I had waited it would get down to about 10 feet... this pic was taken in a room where I get the lowest signal. and I live in a Condo with 2 foot concrete walls.. I don't have a digital camera.. this was taken with my old Samsung dumb phone.. but it does prove you can get a lock inside no problem.. also if i'm in a house I can get 6-7 sats to lock in the condo 5 at the most in that room.
only 3 sats and maybe the walls are thin

LOL Trust me the walls and not thin.. i'm on the 10th floor of a 25 floor Condo complex. I get alot more signal is a house.. Now my X10 can get about 7 Sats locked in the same room. and down to 5 feet. but the point was you can get a lock inside..
I'll try it.
I live in a 3 stories house at ground floor. The shutters are down and I'm 1 meter away from the windows.
After 3 Minutes I get 5 sats in view but none used.
I'll hang on.
Even after 10 Minutes I only have 5 satellites in View and zero in Use.
So no fix for me.
The numbers on top of the bars are from 15 to 25.

LOL... Lets put things in perspective :
1) Wich car navigation software do you use
2) when you UNcheck wireless networks =a-gps(in location and security) and you CHECk "use GPS satellites = build-in gps receiver and then you go outside, you start your car navigation software in you gs( taking into consideration that you have the righ map installed) how long does it take to get a fix so you can start driving?
3) Do you know the difference between a cold and warm start? Why the heck some of you mention car lighters????
Please just answer me these 3 questions and meanwhile I will post some educative information
oi guys ive had a look at a few of those suggested threads about gps and yeah nah they dont really answer my question so feel free to link me to a thread if it answers my question
ok so, what the go.. the phone has gps.. but it doesnt work like a gps device eg navman, tomtom etc.. or does it? i've tried stock froyo and cyanogenmod using that google car app and then going to navigation, but it just keeps searching for a signal for ever. i dont want to use data cause it costs money and defeats the purpose of having a gps.. that is if the phone gps actually works like a gps device. if not then thats pretty bad advertising. anyways let me know, cheers
Mine gets connected to satelites on few seconds,performs as good as my Tom Tom does,i am using Navigon app&maps.
the latest google maps has offline support so you wouldnt need data...
what??! thats rediculous! i left mine in that navigation mode where it was looking for navigation or something like that and the gps symbol was flashing for like 15 min straight as i drove to work and nothing! is it meant to take that long?
EDIT: ok i opened up maps with wifi and it went through all that first time use crap. and so it was using wifi and gps it looked like and that was working. but then when i disabled wifi none of the maps load. only the maps that i had previously loaded while on wifi. wtf? arent maps installed..????????? therefore it should just load them.. what the #%^% im starting to get really pissed off with how stupid this design is. the maps are there, cause theyre installed, and the gps is there so.............. what the ^%#* is its problem?
your right it will only save maps you have browsed while on wifi...i believe there is a setting that overrides this though...

do you know where this setting is? oh and i got the gps to work ie i got it to find me and all that. i did some reading and with gps on most phones the first time they connect it takes a while cause its gotta do all this satellite scanning and then eventually it goes yep ok hes in this part of the country, lets set him up with these satellites and so from then on it connects with gps a lot faster
First of all: the design is just great, you are the stupid.
How GPS work on dah phone ? well just like any other GPS: it receives signal from a few satellites around and it find your position based on the time laps between the reception of each signal (signal come with a time sync).
Now, how WELL does the Legend's GPS work ? as good as any other GPS: very nice in a car or outdoor, but very badly indoor and if it was unable to find your position for 15 minute I'm pretty sure you were indoor (or maybe outdoor in a big city).
Also on smartphone's GPS the data connection can help the GPS itself by downloading some data which will speed up the localisation by satellite, but this is not mandatory and if you're not connected you will end up being positionned. It will only take a few minutes (less than 15)
Finally about the navigation system (which is a bit different of GPS itself) Google's is fairly different than other software because it doesn't come with maps but it download them as you need them:
pros:
-maps are always up to date
-you don't have to waste 2Gb or more on your microSD to store them
-it's free !
cons:
-requires data connection (unlimited download recommanded)
If you prefer usual navigation software, feel free to use co-pilot or navigon or tomtom or any of the other regular software. But you'll have to pay (or crack) them.

whoa whoa whoa hang on now. lets not go throwing the word stupid around especially if you didnt even understand what i meant or you assumed i didnt know how gps works in the first place.
my general question was that it wasnt connecting to gps and the maps werent showing so im thinking you need data for the maps to show even though you have the maps installed, and secondly im thinking something is wrong with my gps or maybe it doesnt work like a normal device navman, tomtom etc because its been half an hour and still no connectivity. then i answered my own question as usual via the internet from other forums i found using google which explained what i said above.
basically with normal gps devices they are already setup with a region.. thingy or whatever it is built into the gps device. this means the first time you connect its actually quite quick because it already has an idea where you are in the world. however with phones, they apparently dont have this so the process of connecting for the first time can range from 3 min, instantly or up to 3 hours like numerous people claimed it had taken for their phones. as for mine it took just over half an hour and now it works fine.
the only question left over now is apparently you can get the maps to show without a data connection through some option change in the settings as someone mentioned a bit earlier.
dont go throwing stupid around mate or assuming anything cause now who looks stupid. besides the design is quite silly since none of this was explained. when they say the phone has gps people (like me) generally go oh wow like those car gps' and expect them to work like that. so when they dont we become a bit skeptical and i was right to do so because look at all this crap ^^^that ive discovered. anyways like i said theres still one stupid thing left about all this which is why data is needed to view maps that are already installed. its like those video games that you install and require you to be on the net to play
You were the one throwing stupid at the design while you still seem to misunderstand how google nav (quit calling it GPS please) works.
Maps are not completely loaded, they're only stored in the cache and that's true only for one scale, and around one place. You can hardly use that to explore the map offline not even mentionning navigating.
The new feature only allow google nav to keep guiding you if you lose connection for a little while. But you can't really use it offline.
I think that design is just awesome, although I have an unlimited data connection. If you don't have that kind of service you should take a look at usual GPS softwares.
And I'm not assuming anything, you asked "how GPS works" not "how google nav works"

ugh forget it, i already answered my own question and now you're just being picky and all technical when no one really cares. i think 99% get what i mean so i dont care
GPS is working great. Google Maps is the "problem", more precisely not a real problem but the way it was designed. Unlike other GPS navigation software, the maps are not stored locally but in a cache. The latest version seems to have an offline mode but I didn't tested so I can't say if it's totally offline or not. If you want navigation without using your data connection or WiFi, switch to TomTom, iGO, or similar instead.
That's why Google Maps has only couple of MB and iGO for ex. has over 2 GB with all maps loaded...the difference is the space occupied by the maps.
P.S. And yes, first GPS lock is acquired a little bit later.

GPS is working great. Google Maps is the "problem", more precisely not a real problem but the way it was designed. Unlike other GPS navigation software, the maps are not stored locally but in a cache. The latest version seems to have an offline mode but I didn't tested so I can't say if it's totally offline or not. If you want navigation without using your data connection or WiFi, switch to TomTom, iGO, or similar instead.

now to that other guy, wouldnt it have been easier to just say that ^
I use Igo for my offline nav. It works just like a tom tom. For my geocaching needs, I use geobeagle.
