The FrSky GPS Sensor feeds variable directional information such as altitude, position, speed, and UTC time, which is displayed in real time on FrSky's Taranis transmitter or telemetry dashboard (DHT-U/FLD-02/FSD etc.) This sensor will only work with the FrSky Smart Port enabled receivers, such as X8R, X6R, X4R, etc. This is a great addition to your Taranis setup.
