Abstract

S band is one of the main working frequency band used by aerospace TT&C (Tracking, Telemetry and Control) system. With TT&C network an increasing scale, the new demands on overall arrangement of TT&C ground station and surroundings of staff are generated. Therefore, the traditional RF signal transmission method has been not suitable. The RF TT&C signal transmitting method use of fiber instead of cable is proposed in this paper. With S band TT&C ground station as a platform, the model of optical transmission signal is established, and the optical transmission equipment is designed. Finally, the testing environment based on TT&C ground station is established, and the performance specifications of optical transmission equipment are tested. Testing results show: the RF TT&C signal can be transmitted 56km long by optical equipment in normal operation condition. The problem of RF TT&C signal long distance transmitting for large scale TT&C ground station is resolved effectively.
