About this app

With this app, you can check the GPS reception in your area and update AGPS data for faster fix times, whilst being able to view other GPS and sensor data. The app acts as a one-stop place for viewing: your altitude, accurate UTC plus local time, your compass heading, the moon phase and daylight hours. It supports GPS, GLONASS, GALILEO, SBAS, BEIDOU and QZSS satellites. The app has various different colour schemes which can be changed according to your tastes, including a night mode. The colour schemes can also be used to match other instrumentation alongside the app.

GPS Test has six different screens:

•GPS signal (SNR) bar chart, showing the signal strength for each satellite, as well as the accuracy and status of the GNSS network

•Satellite positions in the sky (sky view) shown on a rotating compass

•Your current location on the earth shown as text and on a world map. The current position of the sun and the day/night transition curve is also shown

•Compass

•Your current speed, heading and altitude are shown as text

•The current time read from the GPS and the local time in your current time zone, as well as the sunrise and sunset times at your location

OSGB, UTM, MGRS, USNG, CH1903, Maidenhead

Ratings and reviews

This has been quite useful for doing coarse GPS surveys when I don't have anything but a phone available, and having control over the datum used is great (most consumer grade apps don't do this). The one thing that it is missing is the ability to get raw ECEF coordinates instead of LLA; when debugging geospatial algorithms the altitude can be confusing due to geoid corrections etc. and having ECEF coordinates gives an unambiguous description of position relative to the ellipsoid.

Great app that I've used for years, but really needs an update to display dual frequency satellites, whether you're getting l1 or l5 bands. First update in ages and the only thing that's changed is things that used to be free now require a premium subscription. Considering there are much better GPS test apps out there that I use for work and device testing, I don't see any reason why I would pay for this one. It's not expensive, but...

Great app, I just purchased the pro version. One feature request to the developer, can we please have an automatic location saving feature. A screen where we select how long we want to save the location (next 1,2, etc hours or unlimited), location file settings (name, folder, etc), and the frequency to capture the location (every 1/n seconds, minutes, hours etc). Txt file had 1 entry per line. This could be very useful.
