Would be good to share some experience concerning GPS (location service).
Which Rom are you using?
Where is you location? (Asia, Europe, USA,...)
How fast is the Sat-Fix in minutes (only location service, without Gsm, WiFi)?
Sat-Fix indoors (only location service)?
GPS ist working stable?
You are overall satisified with GPS qualitiy?
GPS location service and your GPS program (i.e. OSMAnd+ from F-Droid Store) shouldn't be bBattery optimized.
Which Rom are you using?
International Rom L1657 6.03.02.00 / Kernel 4.9.112 / Security-Updates 2019/09 (incl. Gapps by Default)
Where is you location? (Asia, Europe, USA,...) Europe
How fast is the Sat-Fix in minutes (only location service, without Gsm, WiFi)? around 1 Minute
Sat-Fix indoors? Yes
GPS ist working stable? Yes
You are overall satisified with GPS qualitiy? superior

Hi all
Anyone knows how to enable the internal gps radio on a HTC raphael from Verizon. However i live outside of the verizon network Coverage, and i need to work with the gps. I think that is psooible to enable the garmin software to work with the GPS.
Thanks
I Tried and i'm using this rom, it's WM 6.1 and real GPS unlocked.
- Enable Location mode
- Run Quick GPS, download newest databage.
- Run MAP App (like Google MAP..)
- It's Very Fast conect with satellite.
used in Vietnam via EVDO Rev0 S-Fone Carrier
Goodluck.
Since enabling my vodafone SureSignal femtocell, I'm having trouble getting a GPS lock at home (even out of doors with only low rise buildings around and a clear view of the sky)
Normally this isn't an issue since
a) I know where my house is
b) wifi geolocation under android works fine (and saves power)
but if I'm about to start a long jorney and need satnav, first step is to set the destination before leaving.
My "3UK" phone (so no femtocell -- and awful reception) gets a quick gps lock
Away from home so does my vodafone handset (SGS2) - fw is KJ3 voda official, though I've tried with official, speedmod,siyh kernels - no difference. Furthermore a nexus s experienced the exact same issue.
I believe the cause is the interaction of AGPS with the SS. I do know the SS is registered to the correct postcode -- is this used with AGPS? Also my server is
supl.google.com:7276
Should I be using a vodafone AGPS server insted?
Does the SS play nicely with AGPS?
Thanks
The new update apparantly supports GLONASS, however I've read this:
To save power, the GLONASS receiver is only activated in problematic locations, such as in an urban environment with high rise buildings. Therefore, if you are in an open sky environment where there are enough GPS satellites available to calculate a good accuracy position, GLONASS will automatically be switched off temporarily to enhance the battery lifetime.
When using Endomondo the gps is even worse than my Galaxy S (which pretty much has a crappy GPS). I've tried this using my 2 devices side by side.
Is there a way to either improve the GPS or to forcefully enable GLONASS?
edit: i've analysed my GPX and it appears that about every 5 minutes the GPS signal is lost??? Anyone has any info on this (and maybe even a fix).
GLONASS is quite new, but nice to see it in Sony Ericsson.
GLONASS is automatic and it is not so popular, because only newest SE Xperia phones have its chip. So, there isn't any app yet about GLONASS, at least I haven't found.
I have used my phone's, SE Live with Walkman, GPS in a bigger city without problems. I used app GPS Test(from Market) to check, which GPS is being used. According to me, GLONASS is used only, if you see satellites numbers between 65 and 88.

As far as I know GLONASS is transparent accessible for any application through the android gps-api. So no need for special treadment of GLONASS for the applications.
My xperia active (firmware .42) use GLONASS all the time according to GPS TEST. It always show me satellites between 65 and 88.
GPS Fix is very fast (with mobile data enabled) and accurateness of the gps signal is the best I ever had.

I meant, that application about GLONASS, turning it on and so. I might have said incorrectly.
But indeed, all applications, which use GPS, have also access to GLONASS.
Yes, but according to SE, it seems to only use the GLONASS in urban environements. As I use this device for running, it would be nice to have an "always on" function. I don't really care about battery.
Also: anyone tried to use a tracking application to track the GPS (like mytracks, rungps, ...)? GPS test is a pretty static application and works fine to determine if you get a fast fix but not if there is a tracking issue.
i have the same problem to ..gps signal lost every 3-5 minutes in big city ..
even my x8 have better signal (never lost a signal) i'm using papago~
i just heard about GLONASS (recently on your thread that is)
and i don't even know that it have on our phone !
known issue apparantly since last update (for officials roms)

Greetings!
I am going to Turkey this Saturday with my school, and I am wondering if I am able to use my gps without huge costs?

Last time checking...
GPS is free,
As for data ,
It really depends on the App you are using.
For example :
Google maps requires you to download the maps which would require data.
Try Maverick GPS app
Try Maverick, a GPS app without the need of data or wifi.
You can d/l the lite version for free off the market.
Wont give you a great navigation but it will do the job for free
Also try Navfree.

You can pre-cache a 10milex10mile square in the google maps app but you'd have to know where you were going to go in advance to cache the areas but this can be done during a trip whenever you have wifi and know you're changing cities. No turn by turn or searching but at least you'd have a map you could plot your position on from the phone.
Well, most phones have A-gps, that stands for "assisted GPS": it is not the same as the common gps in Tom Tom devices and so on.
A-Gps has less power consumption, but a weaker receiver so, without the help of a data connection, it would turn to be quite useless, apart from the maps that should be loaded in advance.
GPS positioning data is always free..
You just need the right software to do turn by turn nav (Like Sygic or NavFree / etc)..
You can cache maps off of Google, but that won't give you turn by turn.
Sure GPS connection is free, but data run on 3g or 2g network to assist the GPS. May be it's not a big amount but, if you're travelling abroad, it won't be so cheap
I wonder if the main population will ever understand what a-gps are.
You can use iGO MyWay for android. Easy program and it dosn't connect to internet
Straight from Wikipedia. Now it'll be clear that a-gps needs data connection...
Standalone GPS provides first position in approximately 30-40 seconds. A Standalone GPS system needs orbital information of the satellites to calculate the current position. The data rate of the satellite signal is only 50 b/s, so downloading orbital information like ephemeris and almanac directly from satellites typically takes a long time, and if the satellite signals are lost during the acquisition of this information, it is discarded and the standalone system has to start from scratch. In AGPS, the Network Operator deploys an AGPS server. These AGPS servers download the orbital information from the satellite and store it in the database. An AGPS capable device can connect to these servers and download this information using Mobile Network radio bearers such as GSM, CDMA, WCDMA, LTE or even using other wireless radio bearers such as Wi-Fi. Usually the data rate of these bearers is high, hence downloading orbital information takes less time.
AGPS downloads very little data and it doesn't even require cell service. I have a non activated Android device and using GPS Status it will download AGPS data over wifi. This data is pretty small in size and you only need it to initially lock on satellites faster. Without AGPS data you'll just have to wait longer to get a lock.
For an offline GPS app, I use Sygic since it uses TomTom maps and I've owned a TomTom unit before. But there are other good ones out there.
Yes, there's no contraddiction between all that has been said by both of us. Not a huge data amount but if you are abroad and a roaming area it won't be cheap, because the data flows any time a fix is needed... Just think of tunnels and areas where the GPS signal is weak. I mean, the fix is not one only, it may be 20 or even 100 during an hour of navigation.
Hi guys, i just bought SGS3 in Australia. Everything is perfect and i notice that i can't find AGPS option in my setting ( i saw one picture online that with AGPS option). I reread what samsung said in SGS3 box, I can't find AGPS as well, but accidently, i find GLONASS/ How's ur devices, do they have AGPS or GLONASS?
hello,
On my, i have gps/glonass on writed on the box.
For an appli for AGPS , you can find it on the google play (like gps status).
For the glonass, i don't know if it's possible to connect on it.(i think it depend on the gps appli and maybe the country , only in Russia ?).
Bye
PS: After a little search, i found that the GPS and the GLONASS are active in same time .Now it seems you can find/use 55 active satellites instead of 31 with GPS alone and 24 with GLONASS alone

AGPS = settings Location Services Use Wireless Networks .
Glonass its built in to the cpu .

GPS (USA), Glonass (Russia) and the upcoming Galileo (EU) are different protocols provided by different satellites with different features.
But for everything you as a consumer and user care they are the same.
It's just that consumers are used to it being GPS so they call it that way even if it's incorrect.
If your boss,teacher,friend, ... tells you to google something he means to search on the net and (usually) does not actually enforce you to use the Google search.
In technical terms the app couldn't care less about what country and protocol provides the data, I don't think it even could see the difference (except when polling raw data)
It's very easy to check if Glonass works as expected; just fire up a GPS-Test app (e.g. 'GPS Test') and check the amount of satellites it uses.
GPS is designed with 24-30 satellites total in orbit and as such provides visibility to a mimumum of 4 and a maximum of 12 satellites in clear area.
Glonass has roughly the same amount. When holding my phone against the window I get a (more or less) immediate fix on 17 satellites which is impossible with only GPS.
AGPS is something totally different which regroups network-based GPS with satellite-based GPS, accelerometers and satellite trajectory prediction to allow you to get an approximate fix when it would otherwise not be possible (e.g. underground) and to accelerate the time-to-fix.
AGPS is a combination of gps + mobile network data. With the GS3 you get gps + glonas + mobile networks + wireless networks + sensors (I assume barometer + magnetometer) all working together. I get very good positioning even indoors.

Glonass satellites are detected automatically. I'm in nz and now pick up 17 sats rather than the 12 on previous devices using GPS sats only. TIFF is also excellent, a matter of seconds only for a cold start.

Im pretty sure all S3s have aGPS (Assisted GPS).
Its not really designed as an accurate positioning system on its own - it was originally designed as a clever means to get faster GPS fix by using cell network and/or WiFi provided time and location.
It can also be used to provide less accurate location data to mobile apps (eg GMaps), without GPS.
Per a previous post if you have
System Settings->Location Services->Use Wireless Networks
checked, then you have enabled aGPS
Its a pretty standard thing on most smartphones these days.
