A-GPS on trinity ?

Hi !
I've tried a search on this forum but "no result for this search"
So is there a A-GPS functionnality and how can I use it ? with which soft ?
Thx for your answers (and sorry if it has already answered before )

No AGPS for this Qualcomm GPS.
Beware of placebo effect of avaricum QGPS that some guys are using

A-GPS is supported within the chipset, but there is not yet any software which can access it, and no-one appears to be developing any.

It is not true!
Qualcomm MSM6275 Chipset is A-GPS

So, no AGPS for this moment...
you're right, wait

To be honest, I don't quite think GpsOneXtra Assistance will really come to trinity.
The press release is even much later than its release, and probably even though the chipset supports it, there's still a need for OEM to support it either in the driver or the OS level.
To date, even Kaiser don't support this. So don't hold your breath....

Erm - no A-GPS is present. It is something that is network operator dependent - so to say no AGPS for the moment is not strictly true.
GpsOneXtra Assistance is not the same as A-GPS. A-GPS means that the network operator must implement a dedicated server on their netowrks to manage this and it would not work with roaming.
GpsOneXtra Assistance uses an internet connection to connect to a non network operator dependent server on the internet to get information.
So, we don't necessarily have to wait for GpsOneXtra Assistance and there is, at the moment A-GPS on the Trinity - but perhaps not your network operator.

Yes, you are correct that A-GPS is present in Trinity - but seems that there are few operator (about 50) which actually supports the GPSOne platform in their stations.
See http://www.cdmatech.com/locationservicesshowcase/highlights.jsp
And before every operator supports this crap, I guess the best way to get a quick fix is to have a software solution to download the pre-made ephemeris data and almanac data to the GPS chipset.

Or just go outside for 3 minutes, and get a proper fix!
HTC do support the A-GPS on the P3300 with a dedicated server, but fix times are only a few seconds faster than with GPS alone in many circumstances.

Approximately from 15 seconds to 45 secs...

This is maybe a stupid question! but if my operator supports gpsone platform, then how does it work? is there a software to activate this?

AFAIK there is not yet any software to activate the GPSOne facilities on WM devices.

Something new today ?....
I think that Orange France support this...

...any news?

Still nothing new on this matter?
In finland a lot of people have Nokias phones wich uses AGPS, so I think that its wery well supported by the local operators. But I didnt understand from the messages that is there any software to download from anywhere? Or do we still have to wait? Does anyone know anything more about this matter now?

In Germany O2 sends a cell brodcast on channel 221 giving the coordinates of the next cellphone tower in Gauß-Küger-Notation format (Can be converted to WGS84 gps coordinates easily).
Allso google maps mobile can use a similar system to determine your position when not using GPS (the funny thing about that: people with gps buildin help google maps determine where the cellphone towers are located.)
Now somehow feeding these coordinates + downloaded almanach into the chip sould decrease TTFF + TTF sicnificantly.
But since nobody really knows the functions of the qualcomm chip/driver this is pretty far away from us right now.
My dream would be:
Since I will recieve a Cell Broadcast massage every time i change my cellphone tower a nifty little program will load the Position into the chip (or every time I turn on GPS it loads them in, since I don`t know if the chip can be accessed when GPS turned off [won´t bet on that])
besides of that the same application sould download updated almanach-data and allso load them in on gps startup.
But I think this will stay a dream

Internal GPS

Does Anyone knows how to get the Internal GPS to work with Windows Live Map?
Thanks,

gpsone isn't in standalone mode so it cannot be accessed by applications

There are rumors that it'll be activated in the EVDO Rev A update this fall.

so wait... mogul has a gps?

it's built into the qualcomm cpu like the kaiser. it's assumed the gps shares the cell antenna since there's no gps antenna on board and the documentation states this is possible. the kaiser has the 7200 the mogul has the 7500. kaiser w/ test rom allows for the gpsone to run in standalone mode and the kaiser seems to have an antenna so it works.
as of right now it's assumed gps will work when unlocked but it's still a gray area; there may or may not be an antenna

The FCC application describes the Mogul as
"a CDMA850/CDMA1900 (1XEVDO / 1XRTT / IS-95A/B) Pocket PC Phone with wireless LAN, bluetooth, and GPS functions."
https://gullfoss2.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=391628&fcc_id='NM8TITA100'

the listing of gps functionality is ambiguous; all cellphones are required to have agps for e911 emergency in the usa as mandated by the fcc. gpsone is in quite a few htc devices but only a handful have antennas attached

how accurate is agps? versus standalone gps?

someone on PPCgeeks reported that Live Search was working on Sprint Moguls using tower triangulation. I'm not sure if this is different than AGPS, but it sure it neat to have location based services, even if accurate only to a few hundred yards...

A-GPS = tower assisted GPS.

i had my telenav rep confirm when the rev a patch is released that the GPS will be unlocked as well.

All cell phones certainly DO NOT have aGPS. Please do not confuse aGPS for tower triangulation.
aGPS is assisted GPS meaning it uses the cell phone towers to assist an existing GPS chipset.
So if the Mogul has aGPS, then it has to have GPS by definition.

he is right though. FCC does now require that ALL new phones in the united states have GPS (to an extent) for at least e911.

Yes, I'm aware of the definition.
The way AGPS is described is similar to how articles are describing the technology Sprint and MS are using... and since every Sprint phone is mandated by the FCC to have 911 AGPS capabilities, I'm wondering if this is the same thing.

The Kaiser has a big "GPS" on the back where you can hook up an external antenna. No such luck with the Mogul.
But I still can hope that _some_ kind of GPS would come with Rev.A. Sucky GPS is better than no GPS...

I think you guys know as well as I do, that even if the phone has a functional gps and a antenna sprint will still never unlock it. Its not that they dont want to, they are lazy. There have been lots of firmware "updates" I have been waiting for on other sprint phones that they were going to release and never did.
As for external GPS recievers what do you guys think of this one?
http://www.semsons.com/wo44chawaauo.html
That supports A-GPS you think that would work?

if you are going to go with an external BT reciever any should work, since its not using the phones GPS at all

If you want an external, get a Holux M-1200. Tiny, cheap, and works amazing. I love mine!

ok, so any external gps will work? some of them say A-GPS compatible and others dont. Does that matter at all?

agps rogers

how do i enable agps on my rogers elf plz help

Sadly Rogers touch Elf does not have GPS capabilities. The Vogue is the one with GPS. See Bell CDMA Touch otherwise known as the Vogue.

i know they dont have gps but i heard with 6.1 its to have agps
assisted gps ... which uses gprs not sat

Yes It Does

replay if u have another channel where i can send u the specs of the program and the posibility of sending u the program it self.
Good Luck.

If agps uses gprs not sat then would you incur heavy data use charges? I don't have any type of data plan (they are rediculous in price) besides, where I live, there is pretty much an open wifi hotspot anywhere I go so I have just been using the WIFI whenever I need to. I am interested in learning more. I did some googling and my understanding was that AGPS still required GPS. IF AGPS can work using GPRS Only, what can you do with that? Can you still use navigation software on the device and have turn by turn directions etc..., Can you use it to tell your speed altitude etc.. while driving? If you drive through a zone with no coverage, then AGPS would not work? There are several of these "Dead Zones" in my area in the North of Ontario Canada. (Dead zones for all cell phones no matter who your carrier is)
From what I have read there are a lot of phones that have AGPS however, most have it completely locked up so that there is no way to use it though. (Providers use it for their own purposes I guess - TO SPY ON US) I don't know about the Elf though. Haven't done that much research on it yet. Since there is no official WM 6.1 Rom release (For the Elf) to release the AGPS capabilities, maybe one of the custom roms from this site can do it. If it can be opened up for use with a ROM that is.

Assisted GPS, generally abbreviated as A-GPS, enhances the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones..... Taken from WIKI
http://en.wikipedia.org/wiki/Assisted_GPS

Funnily enough, A-GPS did actually come out as a data based gps solution back when EDGE came to the scene.
But suddenly phones started coming out with their own GPS units installed. UH OH, the carriers said. This imense source of data revenue, is now going to go away.
What to do? What to do?
I GOT IT! We redefine what A-GPS is. Instead of being simply data capable phone tracking system, we take phones with existing, and fully functioning GPS units, convince people that we are actually "helping" the performance of the GPS units with our networks and VOILA, we make even more money than before.
FYI, A-GPS was actually basically the same technology that Google Maps now uses for their "My Location" which is to normalize or coordinate, your location from several cell towers, and have a pretty good approximation of where you are.
All that was required was software (ie MAPS) that could take advantage of this technology that existed from when cell phones came into being.
That is why if you were one of the early adopters of set technology (originally came out with CDMA 2000) companies, you would have noticed that your so called "A-GPS" was as good as your reception was.
So really the more modern A-GPS, should be called GPS-A-CellCOMPANIESmakeMONEY.
But my suggested name did not fly so they decided to stick with A-GPS.

Does Universal Have build in GPS Chip?

Well, was talking to a friend earlier, and she told me government started to ask phone companies to put in GPS chips into cell phones and 99% phones after 2005 have GPS chip build in, so when we call 911, the government can know where we are... at first I though it's not possible, because if is it so, then there won't be phones that actually said "Build in GPS" ? so she said the phone companies just want to earn more$... and yeah I knew how cheap a GPS chips are nowadays... anyway even I though it was a joke or something, I look into it more, and GPS chips build into a cell phone by factory, required by law, seems to be true...
Read it on few other web page saying "Cell phone companies didn't originally want to put GPS receivers into cell phones. But several years ago, the Federal Communications Commission required them to come up with a way to locate their customers for rescue workers and 911 calls."
and "There is a small GPS unit built into the phone, This unit uses the GPS system to determine you location. When you call the cellular 911 operator this information is sent to the 911 system. Below is an Excerpt from the Nov 19th 2005 Milwaukee Journal that dedscribes the system and it's limitations.
Even in counties that will be able to locate cell phone callers to 911, a variety of factors, including the location of wireless towers, tall buildings, bad weather and even sunspots, can affect the system's accuracy, said Richard Tuma, director of emergency preparedness for Waukesha County, the first county in the state to implement the technology.
Two technologies, which work together in most areas, are used to notify 911 call centers of the location of cell phone callers.
One uses global positioning system technology, in which GPS-equipped phones receive satellite signals and relay the location coordinates to the 911 center receiving the call.
The other technology uses three cell towers to "triangulate" the coordinates of the 911 caller.
The GPS system is more accurate, Tuma said, and is capable of locating a caller within 50 meters (about 165 feet) 67% of the time. The triangulation technology can locate a caller within 150 meters 67% of the time, he said. Those standards have been mandated by the Federal Communications Commission.
But each system has its flaws, Tuma said.
To get an accurate GPS location, a caller needs to have a properly equipped cell phone and be standing outside. Being inside any structure, to some degree even a car, can skew the coordinates being picked up from the satellites, he said.
"The GPS system needs a line of sight to the satellites," he said.
Cloudy, rainy and snowy weather also can interfere with both technologies, and nearby tall buildings can throw off the triangulation system, Tuma said."
And I also see this software mologogo can unlock some of the GPS in phones in order to use it as a tracking device...
But since the Universal is made in the middle of 2005, it doesn't have the hidden GPS build in Chip, right?
Thanks

I think the triangulation method is more common for locating callers. The Uni doesn't have built in GPS, if it did they'd certainly advertise it as an additional feature!

Bad news for you - your parents fooled you when they told you Santa is bringing the gifts on xmas.
Don't believe in anything what's written in the web.

there is a slot but no radio rom
Hi SOG,
the Universal hardware has a slot free were you could solder in a GPS chip. The missing chip is a RFR6250. This builds up the GPS backend for MSM6250 chipset.
But there will be no chance to use it, even with the chip soldered.
What is missing, is an ugly hacked radio rom to access the hardware in a proper way.
Regards
Highc

I see! thanks for all the input guys~ I am gonna try to install trackme and see how it goes with my Universal and BT GPS

I use Google Maps
on a few devices. Universal is the only one that does not provide the current location, reads 'feature is unavailable for your device' or something along those lines. So current location has to be entered manually if one wants to get directions to and fro.

I have no problem with google maps and my GPS (although I have sto set manually)

I have no complaints with my gps. I have tomtom. I only need to start my tomtom software and take out my gps device out of my glovebox and press on. They connect automaticly with each other (eg turning on bt and connecting). Im only using gps in my car. So really i maybe only waste 10 seconds out of my life with my jasjar not having gps...

"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.

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.

I can get a lock on 6-7 Sat no problem inside.... and so can lots of others.. don't know what your doing wrong but its not hard to get a lock inside.

Pics or it didnt happen

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.

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.

Most of Tomtom devices got a SiRFstarIII™ GPS chipset
If the GS got such one the amount of GPS threads in this Forum would be reduced considerably
What is your awareness based on?

No, you're missing the point, you don't need any kind of data connection to use GPS, you can use it offline

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.

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
