GPSTest vs GPX Viewer Usage & Stats

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.

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.
