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)
• IRNSS (India) (L5, S)
• 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.

    Five stars. It would be easier for users if some setting options can be given as toggle buttons on home screen such as compass rotation. A great utility.

  2. Snow Vise-avatar

    Developer of the app is very good at what he is doing. And especially a person who is listening user's on what could be done better.

  3. Martin Hogg-avatar

    Excellent maps function

  4. R Imhoff-avatar

    Terrific test tool for inspecting the gps accuracy. Clean stable interface, and it shows the whether the “dual-frequency” GNSS feature is functioning. Additionally the "accuracy" test allows one to compare the device's gps reading with one's actual physical position on an arial photo. Plus it has no ads !

  5. Rick Loughman-avatar

    overall v.good. many issues on an aging galaxy s4 lollipop such as gps time is 20 years and 1 hour off (search: gps rollover bug 19th april 2019) and also niggly UI inconsistencies such as this same app on an s8 on android 9 has different column headers. still... gets a fix and injecting and resetting xtra data can be handy. map view is nice when you don't want the bloat of google maps. free and no ads. 5 stars on newer devices, 1 star on old ones

  6. Jeremy Comer-avatar

    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!!

  7. Joop Reijenga-avatar

    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 :)

  8. Refqah D.-avatar

    Best app for this purpose. However, 1 less star because its name is confusing when someone search for it the store shows other apps with similar name.. I suggest renaming the app to "GNSS Tester" it'll be unique which makes users find it faster and can recognize it easier.

  9. Thomas Polder-avatar

    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.

    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.

  11. Pedro Matos Rito-avatar

    Pedro Matos Rito


    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!

  12. Csaba Gombos-avatar

    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

  13. partha halder-avatar

    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..

  14. Luis Ferreira-avatar

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

  26. bandrec-avatar

    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.)

    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.

  91. Haeddy Wibawa-avatar

    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

  92. Michele Bavaro-avatar

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

  93. Anton K-avatar

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

  94. Hari Nair-avatar

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

  95. Ahmed Elassal-avatar

  99. A Google user-avatar

    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.
