摘　　要：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。Based on the urgent needs of knowledge on characteristics of near-space atmosphere, the analysis and research on the constellation configuration of satellites, which detected atmosphere in the near-space, were carried out through a simulation design of global area by STK in the present study, and this solved the problem to evaluate the feasibility of sensor detection in the way of limb sounding. Taking qualitative but not quantitative weighting method to evaluate the coverage performance, the study focused on the influence of constellation configuration on the detection coverage and local time coverage of near-space atmosphere. Then, the performance of one-orbit-surface constellation and rosette constellation was analyzed using the coverage performance of single satellite as a reference target. The result shows that both the one-orbit-surface constellation and rosette constellation have obvious action on the detection coverage, but rosette constellation can make significant effect in local time coverage only, so it can be conclude that the rosette constellation has a relatively better performance, and this provides a strong technical support to the design of near-space atmosphere research satellites.
