星间链路关键性能指标评估的方案设计

Evaluation Scheme Design for the Key Performance of Inter-Satellite Link

星间链路分系统作为组网星座卫星系统的核心之一,是实现星间测量和星间数据传输的关键。针对星间链路系统星间测量和测控传输误码率两项关键指标,结合星座组网卫星单星和星座状态条件,引入信道静态和动态工作模式,对两项关键指标提出一套全面的评估方案,给出基于该方案的评估系统的实测情况,通过实测数据的比对分析,针对被测系统的星间测量和测控传输误码率指标性能,能够直观地给出综合评定结果,设计方案可以正确、有效地用于星间链路的系统评估,具有较高可行性。

As one of the focuses in constellation satellite networks system,inter-satellite links are the critical function in measurenlents and eomnmnieation of Inter-Satellites. In this paper, attention is paid to measurenlents and eomnmnieation er- ror rate of Inter-Satellites. A comprehensive evaluation scheme is proposed based on this two key perfomlanee indicators by integrating single satellite and constellation conditions, importing channel static and dynamic work mode. Comparative analysis on the real data is conducted from the evaluating system based on this design, which can directly show the assessment result of system performance indicators. The design is feasible, and can be eon＇eetly and effectively adopted to evaluate the performance of the Inter-Satellite Link system.
