GPSTest Description

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 GPS/GNSS 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/NavIC (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://medium.com/@sjbarbeau/dual-frequency-gnss-on-android-devices-152b8826e1c.

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.gl/3RjWX).
• 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.

What is an XAPK file, and what should I do if the GPSTest I downloaded is an XAPK file?

Open up

A file with .xapk extension is a compressed package file. It is a container file format that incorporates APK and additional associated files required for the installation. The XAPK format was introduced to package the APK file and OBB file together for a seamless delivery and installation process. XAPK format can help reduce the package size of application. On mobile phones, users need to install the XAPK installer first, and then install XAPK files through that installer. You can find the installer here:https://apkcombo.com/how-to-install/. But on PC client, you just need to put the file on LDPlayer.

Can I play GPSTest on my computer?

Open up

Yes, you can play GPSTest on your computer by installing LDPlayer, an Android emulator. After installing LDPlayer, simply drag and drop the downloaded APK file into the emulator to start playing GPSTest on PC. Alternatively, you can open the emulator, search for the game or app you want to play, and install it from there.
