The FrSky Smart Port GPS Sensor plugs into the Smart Port on your X series receiver and reports GPS location and speed data.
The Smart Port GPS (GPS V2) sensor is easy to use, just plug it into a Smart Port equipped receiver at one end, and position the sensor so the end marked "UP" has a clear view of the sky. This sensor does require an X series receiver. Early Taranis transmitter users may require a firmware update to take full advantage of this sensor.
Can report the following data to most devices: Altitude, position, speed, UTC time, etc. The Taranis transmitter can log this data for you.
