No ads, and no trackers - GPSTest displays real-time information for GNSS and SBAS 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 GPSGNSS 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)
   • BeiDouCOMPASS (China) (B1, B1-2, B2, B2a, B3)
   • IRNSSNavIC (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 https:[email protected]826e1c.
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 PSDS Data - Injects Predicted Satellite Data Service (PSDS) assistance data for GNSS into the platform, using information from a PSDS server.  Note that some devices don't use PSDS for assistance data - if this is your device, you'll see a message saying "Platform does not support injecting PSDS data". PSDS is the generic term for products like [XTRA assistance data](http:goo.gl3RjWX).
   • Clear Assist Data - Clears all assistance data used for GNSS, including NTP and XTRA data (Note: if you select this option to fix broken GNSS on your device, for GPS to work again you may need to ‘Inject Time’ and ‘Inject PSDS’ data. You may also see a large delay until your device acquires a fix again, so please use this feature with caution.)
   • 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.

    Couldn't fix my GPS issues when they reoccured so a useless app when really needed.

    Sometimes it takes too long to get GPS fix. Otherwise it's nice.

    Lightweight, straightforward GPS app.

    Excellent tool, with a succinct and useful set of data - the best tool for understanding GPS/GNSS issues. Logging is hidden in the settings page.

    Very handy. Installed to see if my GPS works correctly on a custom ROM. The city map and sat radar are very nice touches. Would recommend!

    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!!

    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 :)

    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 !
