The ground station is connected to a tracking turret providing the data link with the vehicle: it tracks it in real time.

To control a remote operated system's vehicle without a wire connection i.e. no umbilical cord, a transmission device is used with a transmitter and a receiver. This device enables command sending, acknowledgement feedback, and sending of the data acquired by the payload to the ground station, plus all vehicle data required to ensure proper mission tracking and control.

Depending on the system and the mission, more or less powerful transmissions are used, and in the case of a very fast vehicle in large 3D spaces the HF transmitter is built into a tracking turret, which automatically tracks the vehicle. Depending on the end requirements, digital or analogic transmissions may be developed.
