Check your GPS reception and save your tracks

Satellite displays global navigation satellite system (GNSS: that's GPS, Galileo, Glonass etc.) data obtained from an NMEA source in your device.
Currently the ModemManager and gnss-share APIs are supported.
You can use it to check the navigation satellite signal strength and see your speed, coordinates and other parameters once a fix is obtained.
It can also save GPX-tracks of your travels.
