First off I'm just a bit confused on the whole GPS thing. I have all the tutorials and stuff but will the GPS actually work without the data plan? (aGPS).
I have..
Radio: 3.42.50 Bell Radio
ROM: NFS 1.12VZW
I cant seem to pick up any signal at all...
Any help would be appreciated. Thanks!
GPS will work with out data plan, but maps are loaded from internet most of the time..
also it *might* pull data, that you shouldnt be charged for, aGPS uses a tower to determin the GPS clock and basicaly jump starts your lock by a min or so. with out it, your phone would search for GPS signals and try to sync its time with it, befor lockign on to all 3.
with aGPS it only uses a tower and 2 others
Hi Guys,
Here is an excellent article covering gps vrs agps:
http://www.wmexperts.com/articles/gps_vs_agps_a_quick_tutorial.html
As spyderekz said, our Vogues are capable of "stand-alone" gps. Having said that, agps is more accurate.
I am an Airline pilot with Air Canada Jazz, I have tested my gps in the air (with the phone in airplane mode), and the gps was able to lock. GPS sattelites are all numbered, both TomTom and gps viewer (GPS viewer is included in NFSFAN's ROM) display GPS status pages. These pages show how many sattelites you are recieving, and their numbers. Our Aircraft FMS (flight management system) has a similiar page. Both my Vogue and the aircraft picked up the same sattelites (The airplane picked up more, then again, MUCH bigger antenna!!!).
I also live in BC, I have used TomTom driving many mountain passes with no cell phone reception and TT keeps ticking along nicely.
I should add I'm on the Bell network, and Bell has not locked any GPS functions unlike Verizon where users must jump through many hoops to get it working.
Quick question tankbusta, what network are you on?....nerermind, just noticed your Verizon. Have you tried the stock Verizon ROM, complete the agps fix, then flash to NFSFAN's ROM???
If you search the posts, you'll see NFSFAN recommends using your own carriers radio, and letting ALL customizations run when upgrading that radio. As long as Verizon has a 3.xxxx radio, you should be able to use the tutorial to get gps working.
No problem using TomTom.
hi i was wondering if anyone knows what is the 6digit epst code that you get from getspc for a htc touvh 6900???
It is "000000"
So this past week I was having tons of issues with the cell-tower triangulation on my Nexus One. I've tried multiple things such as restarting, toggling the "Use Network Location" and mostly everything short of resetting the phone to factory default.
So I was playing around in the Applications menu and decided to just mess around with all the items there. Then, after clearing the cache on the "Google Framework" option, force closing, then restarting my phone, I was finally able to get cell phone triangulation working again!
The problem continues though, because after said procedure I was unable to access the market, or the downloaded section of the store only had 2 items listed. So I did another restart, the market works, but the cellphone triangulation breaks again.
Does anyone have a solution?
well sounds like somethings haywire on the software side of things, i'd try a factory reset/reflashing your current rom etc. or you could just use GPS i suppose

Market problems are generally due to the ROM you're using, although most cooks have that sorted immediately. What ROM are you using?
And I've never heard of anyone anything on the Framework, maybe that in itself was kind of dumb? Have you rebooted or such to see if it clears up?
So what is the issue anyway? Where are you observing that cell tower info isn't working? And you've double checked, and maybe toggled off/on the setting for this?
OP, does triangulation work for you on EDGE?
I've been in this state (2G triangulation works but 3G does not) for about two weeks now.
Most probably a T-Mobile or Google data base issue...

This is true, at one point T-Mobile and 3G the lookups didn't work.. but I haven't heard this in a long time so I'd think
I really wish people would stop referring to it a "triangulation" though, it's estimation based on tower location and possibly data from Cell+Wifi+GPS data that Google has collected. There's no calculation going on.
I am glad someone brought this up. I thought it was just me.
'Estimation' works with EDGE on, but not otherwise. If EDGE is off, Google Maps takes me to the last estimated position!
I am sure something is broken in Maps.

OK, I believe accurate terminology would be "multilateration"
(there is an excellent Wiki article on this) which in turn is based on triangulation. The calculation is done either by the network, e.g. T-Mobile, or by Google based on the location of nearby towers...
I have the same problem as the OP. It occured since Tuesday of last week. I am also on Rogers in the Toronto and GTA region. Use wireless networks is checked under settings. The Enable location setting in the browser is also checked. However, when using 3G, location is unavailable when using the browser and it is also unavailable in the news and weather widget. RadioTime does not pick up my location either. In addition, when I travel into Toronto, the location in google maps is not updated to my new tower location. The location remains in Markham. Strange thing is that when I am on WIFI, location is available. I have tried using EDGE, same problem. I have also tried resetting to factory settings but no luck. I can confirm one of my coworkers is getting the same problem also on his N1. I don't think it is Rogers' problem since iPhone and Maemo users are having no trouble for location service on Rogers. I don't see how it is a problem on Google's servers either if location service is working for users of other OS. However, I don't know if any other Android devices on Rogers are having the same issues though. Can other Rogers users, Big 3 users, Wind/Mobilicity users confirm if their N1's are having the same issues? On a side note, my N1 is stock.
As far as the ROM/Phone. I am using the official FRG83D without any root or modifications to the firmware/bootloader.
It would not pick me up using Edge/wifi/3G and the only thing that did work was GPS. The weird thing is, it appears to be some issue with a service on the phone. The reason why I believe this is because if I went on the mobile Google, the page didn't ask me for permission to access my location.
After I cleared the cache on "Google Framework" and rebooted, everything worked fine and the browser asked me for my permission.
As madballs mentioned, it doesn't seem to be a Rogers issue as I was able to pop the sim card in my XPERIA and it was able to locate me just fine.
After going insane and going without sleep for the past 30 hours, I have linked the issue with the update to Google Goggles. Got rid of the update, location now works fine.
My N1's tower based estimation works ok on Solo (Bell's network). The estimatation is not as good as my Nokia N85 when I put the same SIM card in...
So I got into work today and same thing happened. The location services does not recognize that I am now in Toronto and not Markham. However, I tried out what the OP suggested and cleared the cache in the Google Services Framework and restarted the N1. It then recognized I am now in Toronto. This is quite strange. What does Google Services Framework do? And why would it not update when I travel into another location? It only stopped working last week. I will see if it changes back to Markham tonight when I get off work tonight. If it doesn't work, I will try deleting the Google Goggles update.
Same issues here ...
I am stock FRG83G on Rogers in southern Ontario. Been having this issue for a while but never bothered to look into it. I tried some of the tricks in this thread and here are the results:
- went to 2G - no improvement
- removed updates from Google Goggles and rebooted - no improvement
- Cleared cache and force stopped the Google Services Framework and rebooted and location is working.
I will edit this note if anything changes.
Update: Looks like clearing the framework loses your history of free downloads from the Market ... the paid items are still there.

Oops.. But try this, launch AppBrain, sync, then exit Appbrain and try the market again. I noticed by accident once after restoring all apps using Titanium Backup that before I went into Appbrain the Market didn't know about my installed apps and afterwords it did.

If you restart again, the Market will work correctly again, but the location services will break.
Same issue here on stock FRG83D since November 15.
I've tried both Rogers and Fido SIM cards. I've also done a factory reset and rolled google maps back. Nothing seems to resolve the issue so I've resorted to enabling GPS when it's available.
The same thing started happening to a friend's Acer Liquid E running 2.2 earlier this week. After clearing the maps data on their phone the positioning worked as expected once again but latitude isn't providing the correct location.
Today my N1 refused to update its position. After clearing the maps data it started to work properly.
Both phones are on Rogers and being used from Hamilton to Toronto...
Quick update. As I mentioned on post #11, I had to clear the Google Services Framework cache this morning before the N1 recognized I have left Markham and arrived in Toronto. I am in Markham now, and the N1 automatically recognized I am back in Markham now. Honestly, I have no clue what the problem is. As I stated, I have reset to factory setting a couple times the past week. I would tend to believe by reseting to factory setting is equivalent to clearing the cache. However it did not work then. So I dont know how by clearing the Google Services cache would work today. May be it is just a coincident. I will post again tomorrow when I am back in Toronto and see if the N1 recognizes the location by itself. Oh right, another thing tried was putting my friend's SIM card (he has a iPhone 3GS) into my phone, but no luck. I didn't bother giving him my SIM card to try since another poster on here said his SIM card works on his XPERIA.
beermike: Location services wasn't working for me on November 16th. Right before Eric Schmidt made his Gingerbread comment actually. I wish this hinted that Gingerbread was coming but then it's only us Rogers/Fido users having the problem.
P.S. This is probably not a Rogers issue. But I have to say, Rogers sucks. Too bad I'm on a corporate plan with them.
EDIT: I found another thread that some AT&T folks had this same issue back in May http://forum.xda-developers.com/showthread.php?t=679636
Restarted phone yesterday night and location services is not working today again.
I believe the correct term all of you gentlemen are looking for is "A-GPS" or "Assisted GPS".
Per the issue, are these results being achieved with the GPS hardware setting turned OFF, and the mobile network/AGPS turned ON, or are both of these settings turned on and still unable to find an accurate position?

No, it's NOT assisted GPS as that includes the GPS, yes? As mentioned, it's more of this nature: http://en.wikipedia.org/wiki/Multilateration
A-GPS is when your cellular provider offers the phone ephemeris data which reduces the amount of time the phone has to calculate the satellite positions and improves accuracy and the ability to maintain a fix because the phone already knows where the satellites are without downloading such data directly from the sats themselves. And in this case of course you're using the GPS, not an estimated location based on your nearby cell towers.
Assuming tower location is correct (and KNOWN...), if you only have one visible tower you should basically show up as being at or near that tower. If there are multiple towers, some set of parameters allows some estimation or predetermined location based on the results. I've read multiple times in the past that when the GPS is in use on a cellphone and My Location (what Google calls the cell tower location stuff of course) is in use, it will upload anonymous data to improve their database. There are multiple such databases, although most of them would only place you at the known location of the tower and not take into account multiple 'visible' towers.
Here's an OpenCellID lookup: http://www.opencellid.org/cell/get?mcc=310&mnc=410&lac=15913&cellid=50762 If you look closely, directly east, across the shopping center there and just into what looks like a bit of an industrial work area there's a square patch with a shadowy place; that's the tower it's referring to.
My old phone could not run GPS without a data connection and that sucked, massively when I was overseas.
Does anyone know if the Nexus 4 is the same way, or if there is a way to run GPS without a data connection?
Thanks!
I've never heard of a phone that didn't have a separate GPS radio. If like you say your old phone needed a data connection then that wouldn't have been true GPS and was probably using triangulation between cell towers for location and that's a different beast all together. On every android device I've owned since 2010, including the Nexus 4, GPS is a standalone feature.
Your question is confusing. If you're asking if you can use all GPS features without data, in other words navigation/etc the answer is yes. However, Google Maps does not support those features without an active connection, you will need to purchase or obtain a standalone GPS application for Android (Garmin for example has one).
GPS will return location data, but Google requires a data connection for directions. You can download maps for offline use in My Places, but you will still need data for routes and directions. You can buy offline Nav apps for total offline use (CoPilot is one of them).
You might want to check into Backcountry Pro if you're looking for 'offline' GPS support that also has to support things like topographic maps and way points (primarily for backpacking, hiking, and camping). You should check into something like Garmin's app if you need directions and road maps offline.
So basically, if I use gmaps on my Sony Z Ultra, it's shows an accurate location of where I am.
If I use phone tracking or locating software, it shows my phone in a location a several miles away. Totally not useful if I really lose my phone.
I've tried different program, like Wheres My Droid, Locate My Droid, Avast mobile, Norton, Mcafee mobile security, MyXperia service, and even Google's own phone locator under device manager (yes, I really tried them all). They all show the exact same location too.
I've tried using only GPS, using only WiFi, letting google using location access, denying location access, using GPS Test Plus to clear AGPS, update AGPS, tried it when phone was stock, with a flashed newer radio, old firmware, newest firmware, changing GPS settings to China (where I live) via GPS Status and Toolbox, FasterFix, ActiveGPS, all individually of course and then a couple together as I read in other forums around the interweb with users having GPS problems, but still nothing.
Why the heck would gps maps on my phone, using google maps for example, be perfect, yet when using google maps (or the plethora of other phone tracking programs, some which utilize google maps, other which use their own) on my PC to track my phone, they ALL show a location several miles away?
How does Google Navigation work? Does it depend on GPS or cellular network or both?
I have a Tmobile Note 3 and sometimes, when my mobile data is showing "E" the Google Maps app can't even get a GPS lock?
Is it the phone? Do I have a lemon?
My friend has a Galaxy Note 3 on Verizon and her Google Maps worked just fine. Her data was showing 4G LTE.
Is anyone here an expert on how Google Maps works? I thought it only needed GPS? I tried all the different GPS settings ("full", power save, GPS only, etc) and none of them made any difference.
I m not an expert, just sharing with you what i know, Google maps can work only on gps but with data pcg locking to gps & loading of maps will be much faster, navigation is a feature now built inside Google maps required internet for navigat to certain destination.

you can use Google Maps without GPS also, its gets location from the cellular towers around you. but its not always perfect as towers can be near you or far away
So for perfect accuracy GPS is required. GPS lock depends on many reason.
Thanks! Is anyone else using Google Maps/Navigation on a Note 3 with Tmobile?
How good does it do GPS lock?
You know one thing? If your maps are cached, you don't even need internet to get a GPS lock......

"E" mean edge which is 2.4g network and slower internet. with "E" the maps slower to download map images, sometime very slower it cant load the full map and it stuck. as the map not loaded the gps doesnt work.
I'm not on Tmobile but whenever I'm traveling on rural areas out of the city, it doesnt work properly until it get a HSPDA network. and for this situation its better to keep it in high accuracy mode, but without gps the navigation doesnt give proper location.
Google maps can work only with gps & data/wifi...But i think if you search on the internet, there is a way to work gMaps and navigate offline!!
google maps uses your data and GPS.
you can 'download' areas to make it work without data and only on GPS.

When I'm on "E," it says "Searching for GPS" like forever and never locks. It's quite frustrating.

Try do the same thing on a high speed network like wifi, hspds. If that doesnt work go to app, clear all google map app data and cache and then try again.
Please make sure if you have the issue with the GPS hardware then it will does same on highspeed network too. Mine does something same, but i forgot how it does on Edge.
Also what type of cover you're using, if any. magnets of cover sometime malfunction hardware, like compass spen etc, mine effect on spen. So if you're using any cover with magnet the try with removing it.
According to me this phone could malfunction any hardware, its nothing weird, mine vibration doesnt working these days, its a 6month new phone and never dropped.

The GPS lock works fine when I have LTE. But, the arrow thing looks like it's drifting when I'm driving sometimes. For example, it sometimes doesn't point in the same direction that I'm driving. I tried resetting my compass with the figure 8 trick already, doesn't help.
I have a TPU cover.
Let's start from the beginning:
You can set what is used for your location:
under KK my phone has following options:
1 High accuracy - uses GPS, wifi and cell network
2 power save - uses wifi and mobile network only
3 gps only
So the question is not "what is used for location", but "how is your phone set up?"
Any other setting but 1st, will have issues.
if settings are proper then try using GPS test or gps status program to see if hardware is working properly. if that's ok, maybe need to clear cache or reinstall program.
