At the top of the Information page you can see the GPS Status (Last fix, 2D, 3D, Bad, None etc). Next to that some characters are listed. What do they mean?


They are the senteces which are being decoded from the GPS input stream.


Something like GTWAV may be listed after the GPS status message where

G = Groundspeed from GPS

T = Track heading from GPS

W = Vario from a pressure sensor source

A = Pressure Altitude from a pressure sensor source

V = True Airspeed from a pressure sensor source
