GPSTest displays real-time information for satellites in view of your device. A vital open-source testing tool for platform engineers, developers, and power users, GPSTest can also assist in understanding why your GPS/GNSS is or isn't working.

Supports dual-frequency* GNSS for:
• GPS (USA Navstar) (L1, L2, L3, L4, L5)
• Galileo (European Union) (E1, E5, E5a, E5b, E6)
• GLONASS (Russia) (L1, L2, L3, L5)
• QZSS (Japan) (L1, L2, L5, L6)
• BeiDou/COMPASS (China) (B1, B1-2, B2, B2a, B3)
• Various satellite-based augmentation systems SBAS (e.g., GAGAN, Anik F1, Galaxy 15, Inmarsat 3-F2, Inmarsat 4-F3, SES-5) (L1, L5)

*Dual-frequency GNSS requires device hardware support and Android 8.0 Oreo or higher. More at

The "Accuracy" feature lets you measure the error in your device's position against your *actual* location (entered by you). Other apps show you the *estimated* accuracy, which is generated by your device. GPSTest lets you to compare this estimated accuracy to *actual* accuracy!

Menu options:
• Inject Time Data - Injects Time assistance data for GPS into the platform, using information from a Network Time Protocol (NTP) server
• Inject XTRA Data - Injects XTRA assistance data for GPS into the platform, using information from a XTRA server (see for details on gpsOneXTRA)
• Clear Assist Data - Clears all assistance data used for GPS, including NTP and XTRA data (Note: if you select this option to fix broken GPS on your device, for GPS to work again you may need to ‘Inject Time’ and ‘Inject XTRA’ data)
• Settings - Switch between light and dark themes, change map tile type, auto-start GPS on startup, minimum time and distance between GPS updates, keep screen on.

Reviews From google play store

Does what it says on the tin. Not all carrier frequencies for the E5 bands are properly labelled, likely due to dev being in the US where Gallileo isn't operating yet, but just keep in mind anything much closer to 1600MHz than to 1100MHz is an E5/L5 or similar frequency band (so on the new, dual frequency GNSS bands) and you'll be set.

Does it calibrate the GPS? There isn't a option for it when others provide that. Awsome application. I'm very impressed with everything so far and considering it's free and without adds! Amazing!

Small, precise, fast, ad-free, works nicely. What else could I need?

would be a 5 for me if it showed the list of satelites grouped by types like GPS,Glonass,Beidou. other than that, one of the best for app so far I have seen! grat Update: by default the short is by constellation, that is sorting, not grouping

Suck it polaris this is ad free and actually works

the BEST GPS~test and FREE! 5 STARS FROM ME!

fast, noninvasive, ad-free app. unlike many of the other GPS test apps, this doesn't require unnecessary access to phone data, camera etc, it just needs location. app is quick to locate satellites and provides good info. interface is basic, but is clear and easy to understand. and no ads!! its like it was built by people who just care about making a good tool. good app!!

Helpful app, useful for getting detailed technical info about GPS and diagnosing issues with your device.

GREAT!! Very good app!! Found the link on Github. Helped me finally figure out why I got no TTFF reported with several GPS apps I use. All worked on older phones/tablets but not on Android 7.0. TTFF first didn't show up in this one too till I turned off the "use GNSS APIs" in the provided settings options. Then TTFF showed up correctly when letting it use the legacy GPSStatus.Listener. Searching on internet didn't give me a hit on a bug in these APIs but as it seems there is? I've turned GNSS usage back on again, being more accurate as I understood. Anyway, thnx dev for this great app. Love the map future too BTW :)

Works great! Does exactly what it says. 100% open source app and great fix to update GPS location / toggle phone to reset the GPS and refix your location.

Unlike many, many other apps out there this one actually does what it's supposed to! With no ads!

very good app,but i have a few questions why there is two altitudes? first one is in (-)tive always,what it is??.. second one is MSL altitude this one is correct..

fixed i think, no more freeze, just a delay when switch to map.

This cannot be anything but 5 star. Great satelite, freq, ss info, a lot of derails on the fix and no ads. Great thanks to the developer.

Excelent. In English and many other languages ! The language depends on the current phone language.

Clear and informative app, very useful as a sanity check when used with Viewranger. Open source too.

Great app. Simple to use, does the jod well, immediate gps fix with all the info, free, no adds or payed content, even has a datk theme.

First I had another "GPS Test" app (the one with the colorful icon), but that was just a toy. Now this looks interesting.

Nice overview of GPS constellation and phone capabilities. Very handy utility.

Hello! Great app! I see Indian SBAS in the list. Does it mean my device only supports Indian SBAS? (I can't see any SBAS satellite @ "Sky" view.)

only app i found to display gps time and location. perfect for astronomers who need it for telescope alignment.

Excellent app. Really useful. Simple but informative interface.

Excellent ! Precise, free and open-source.

Great! works better than the ad infested app alternatives I've tried

Ad free and works, unlike every other GPS test app out there.

no ads, does what it says. :). happy user this side!

The image is always shaking....and I cannot stabilize it.

For free and no ads this app is awesome! 👍

Can they please add to the map were to and were go to on the map..

finally a good gps info tool!

Simple app that do what I want. Nothing else. Thank you!

Can they please add to the map were to and were go..

Can include support for Huawei mate20 Pro? I suspect my GPS is not dualband as advertised, please help

Excellent app. Does what it say.

no ads nice

very useful application

App is quite good compared with other apps

fantastic app!!!!! so cool

it's a good proper app


Great application!


awesome app

Best GPS tester

instant response to my location great look and graphics

Good app.


Pretty cool


Great replacement for "GPS Status" which seems dead or dying. A few minor issues but nothing major (like sky view being oversized in landscape mode).

Excelent app




Developer is definitely has good knowledge of Navigation

Works perfect


Great app! Could you provide an info page? I know that "acc" is accuracy but I don't know other labels' meaning...

Brilliant, does exactly what it says on the tin.

As good as it gets! Kudos!

No ads or analytical trackers in their app code. Kudos to the developers! Very rare find these days

No ads , very stable , feature rich. Just hope that the google map will be replaced by a offline map and it will be perfect.

Excellent app! ps. Please consider adding sat with ID38 in sat list. Thank you.

Great app and no ads. Very good developer that keeps the app as updated as possible.



Good app, but I really dislike a map that doesn't stand still facing up north. The tilted map style is for programmer's amusement only, to look cool, it is mostly irritating and annoying for user who really use map for guidance.

Please use white text on black not grey text on black. Grey is much more difficult to see in the bring sunshine. Thank you.

Very Helpful

Best GPS Tester - I tried a lot. Reset GPS Data fix slow lock!

gpstest really a great open source app for exploring GPS information on Android device!

Excellent! But with hi-res icon will be better :)

GPS fixes really fast with this! Just need Internet connection once after clicking the two inject buttons, then you're set to go! :)

Many big big thanks for developer who build this app... about 2 weeks my GPS won't fix at all and I totally can't use my navigation app, then after installing this app everything works flawlessly and fast... thank you

Only lacks NMEA logging but that's totally acceptable as the app work super well, fast and reliable.

Requires Google Maps, which take extra 50+ MB of space... If you need pure GPS test, use another app.

Excellent functionality, simple to use, minimalistic and simply does what it states!!!

Thanks developer for that app it helped me a lot fast and reliable accuracy .. really helpful

Guides me to accuracy

Not working..

Some instructions would be nice

GPS Test is a very handy app to quickly check your GPS, get a GPS fix quickly by injecting time and to quickly see where you are because it include a Google map. The only issue I have is the reported altitude, it does not take geoid altitude into account. I'll give 5 stars when that is implemented.

Superb app. Thanks for make.

Весьма увеличивает количество спутников на связи, повышая точность позиционирования.

It does not work......

Use this app to help jump start the gps signal. Works consistently.

Saw both Navstar and GLONASS sats, lots of useful diagnostics for us spatial data geeks, in my permanent arsenal.

Don't even consider trying anything else.

Super simple and efficient tool!

D old version work great on me.. Can i have d old version back???


Thanks a lot

I currently have alpha and beta tester roms running ics on desire z and tf101 and no other program would allow my gps to lock after replacing some system files, this little baby kicked it back into action. Thanks a lot i was going to have to revert back to GB and HC =[ but now i dont have to. :-) ..smooth..

Great geeky app for pure GPS. About 1/10 file size over almost anyother GPS app. Clean skyview(but not quite sure what the colours mean) Main issue is Not properly Closing upon exit. Has to be Forced-Close. If not for that, 5 star rating.

I've been downloading crap and flashing and reflashing roms for days for nothing! turns out, all I had to do was download this app and....tadaa good as new thank you so much for a minute I thought I was gonna have to go back to stock rooted but now I get to keep my rom the way I like it ....YOU ROCK!

My GPS was useless until I tried the Clear Aiding Data option this application has. It is a great app., i recomend if your gps can't lock satellites.

OK, but still runs on the background after exiting and leaves GPS active. Had to FC to stop it. Not good. Uninstalled.

GPS had stopped working...always searching never solid green. Installed this APP and ran test ... Back in business. Also has sky view...really cool!

I think this is the best gps test after the other gps test failed to detect satellites and lock gps.. this app lock gps in just within 1min compare to other that took forever! -samsung galaxy ace

Tried to "adjust" GPS function on my Gio. With all other apps it was an neverending story - 5-10 min every time to GPS lock, EVERY time - not only when starting "from cold". But this little app is really wonderful tool, just because it WORKS! Less than a minute, and I can see the sky full of satellites! ))) Thank you, Mike!
