针对国内外临近空间大气特性研究的迫切需求,对临近空间大气研究卫星的星座构型进行了分析与研究,采用STK对全球区域进行了仿真设计,解决了以临边探测为观测方式的载荷探测可行性分析论证问题。采用对覆盖性能评价指标作定性不定量加权的方法,研究了星座构型对临近空间大气探测的探测点覆盖和地方时覆盖的影响;并以单星方案覆盖性能为参考目标对同轨道面星座和玫瑰星座进行性能评价及对比分析,仿真结果表明同轨道面星座和玫瑰星座对临近空间大气探测的探测点覆盖都能有明显的优化作用,而只有玫瑰星座对临近空间大气探测的地方时覆盖有显著的提升,最终得出以玫瑰星座为优选构型的结论,为临近空间大气研究卫星的设计提供有力的技术支撑。
In view of the urgent need of researching the atmospheric characteristics of the space near home and abroad, the constellation configurations of the near-space atmospheric research satellites are analyzed and studied. The global regions are simulated by using STK to solve the load detection Feasibility analysis demonstration problem. The method of qualitative and quantitative weighting of the index of coverage performance was used to study the influence of the constellation configuration on the detection point coverage and the local time coverage of the near-space atmospheric exploration. Based on the coverage performance of the single-star scheme, And Rose Constellation for performance evaluation and comparative analysis. The simulation results show that the orbital constellation and Rose Constellation can significantly optimize the detection coverage of the near-space atmospheric exploration, while only Rose Constellation covers the local space exploration near space The conclusion is that the Rose Constellation is the best configuration, which provides a strong technical support for the design of the satellite near space atmosphere.
