To make sure that the antenna points to the right direction is the basis of effective work of telemetry and telecommand system of a helicopter. The accuracy, reliability and tracking mode of an antenna tracking system are discussed, and specific problems associated with its application to the helicopter are solved. Comparing with normal angular tracking system, this system is demonstrated to be simple, effective, reliability, low cost and feasible for mobile base station. Now this system is going to be put into practical use.
