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


•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

I like this app for getting some idea of altitude. When you're looking at homes and trying to determine flooding potential. Sure, there's some variation in the altitude but at least you get some idea. Maidenhead coordinates are used by ham radio operators. Unfortunately, the Maidenhead coordinates are coming out backwards. Once you know that, you can work around it but prior versions didn't have that problem.

Maidenhead is fixed. Version 1.6.2 is now fully released please give it a try.

I'll start off with a "back handed compliment"... I've given up looking for reasons to like this app and I'm now searching for reasons to dislike it -- and so far I am unsuccessful. I really like the simple, logical layout and feature offerings from simple Long/Lat to GPS time to location mapping on a world map (showing daylight and nighttime regions). I was also offered 4 hours of full features (i.e., the upgrade version). Near as I can tell, the benefits are modest, but I be paying anyhow.
