微纳卫星测控通信统一系统的研究与实现

Research and Implementation of TT&C and Communication Integrated System for Micro-satellites and Nano-satellites

与微纳卫星特点匹配的测控和通信已经成为了一项重要的研究课题。本文从微纳卫星体积小、重量轻、成本低、研制周期短和功耗低等特点出发,参考统一S波段测控通信系统及CCSDS“高级在轨系统”建议的虚拟通道概念,提出了一种适用于微纳卫星测控与通信的测控通信统一系统,介绍了星上及地面模块的设计,并就此系统对微纳卫星的适应性进行了分析。最后,通过其在我国微纳卫星上的实现,验证了此系统的有效性及可靠性。

A TF＆C （Tracking, Telemetry and Command） and Communication Integrated System was developed especially for microsatellites （about 100kg） and nano-satellites （about 10kg）. Some methods of Unified S-band System （USB） and Virtual Channel （VC） in Consultative Committee for Space Data Systems （CCSDS） were taken to accommodate the traits of these satellites which were little- size ＆ light-weight, low-cost, short-period of development and low-power, and to solve the pioblem how TF＆C could be integrated with Communication in one system. Celestial and terrestrial structures of this system were designed with modularization, and then its applicability for the satellites was analysised. The implementation of the system in micro-satellite TH-1 and nano-satellite THNS-1 validate the effectivity and reliability.
