1. PSDS is the generic term for products like [XTRA assistance data]( ). • 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.

2. GPSTest lets you to compare this estimated accuracy to *actual* accuracy! • Inject PSDS Data - Injects Predicted Satellite Data Service (PSDS) assistance data for GNSS into the platform, using information from a PSDS server.

3. 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. • Various satellite-based augmentation systems SBAS (e. g. *Dual-frequency GNSS requires device hardware support and Android 8. 0 Oreo or higher.

4. 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".

5. 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.

6. No ads, and no trackers - GPSTest displays real-time information for GNSS and SBAS satellites in view of your device.

7. The "Accuracy" feature lets you measure the error in your device's position against your *actual* location (entered by you).

8. Other apps show you the *estimated* accuracy, which is generated by your device.

9. Don't have Google Play Services on your device?

10. Nostalgic for old releases?

11. If you want to see the map on the Map tab, you'll need to install Google Play Services.

1. Still, FOSS, ad free and with attention to detail, even supporting multi-frequency data, so definitely a recommendation.It doesn't have many features, which is fine because all the features it does have are more or less first rate and the primary ones you would want.

2. This app (and the "GNSS Logger" to which I suspect it is related) do a great job - but I have found that both apps randomly stop - but then restart - logging of data.

3. 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.

4. 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.

5. Plus it has no ads !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.

6. This probably wouldn't matter much if one weren't trying to build track logs for comparison with other GPS receivers (Garmin ones in my case) but it caused my to remove one star from what would otherwise have been a perfect score.Excellent app.

7. unlike many of the other GPS test apps, this doesn't require unnecessary access to phone data, camera etc, it just needs location.

8. First, a feature that causes the software to only use satellites that have dual-frequency signals? Would that help? Second, increase the displayed resolution (in each format) to 3 cm or smaller.

9. A detailed information screen toggled by activating a satellite that lists even more information, like the satellite's time or height, might be a useful addition.

10. Fourth, eventually RINEX support, for post-processing.I've been playing with a lot of GNSS application lately, primarily with the NMEA sentences they emit.

11. Should be great to be able to choose which data is shown in the notification area.fast, noninvasive, ad-free app.
