FrSKY GPS sensor

This is the FrSKY GPS sensor which enables position, altitude, speed and distance data on the Taranis. Cost about A$49.

The UP side must face upwards with a clear view of the sky, under foam may be OK.

Once connected it takes a few minutes for the sensor to acquire satellites. 

When it is ready the red led will change from fast to slow flashing and Lat and Long will appear on the telemetry screen 3.

This video covers connection and setup, how to enable spoken altitude, speed and distance values, telemetry logging and displaying flight tracks in Google Earth.
