Design and Realization of the Ultra-violet Imager Communication and Control System Based on Packet Utilization Standard

For conventional satellites in China, telemetry and tele-command system has limitations due to the format inconsistency. As the payload becomes more complex, the format of the communication system requires rebuiltion and many constraints in operation will be produced due to the lack of flexibility. For Ultra-violet Imager (UVI) instrument in SMILE mission, a new strategy for the communication system derived from PUS (Packet Utilization Standard) is used for the efficiency of data handling. In this paper, principle of the communication system and the description of PUS standard used are presented. Then each section of the communication system is described in detail. Finally, the integrated test of the completed system is carried out. The test results show that the system is stable and could meet the requirements. This system can be used as a reference for the engineering application of the PUS in other satellites in China.
