低地轨道小卫星星座优化问题研究

Study on the optimization of the LEO small satellite constellation

以低地轨道小卫星星座为研究对象 ,着重从星座覆盖性能考虑出发 ,详细阐述了局部覆盖小卫星星座优化设计的一般方法与思路。针对某一类型任务对两轨道面和三轨道面星座进行了优化设计 ,阐述了在一定约束条件下星座优化设计的关键因素以及不同轨道面数目下星座优化的潜力和特点 ,并进行了仿真分析。

The low earth orbit satellite constellation is used for the discussed object in this paper. Regarding coverage performance as an important consideration, it states the general idea and method of the optimal design with the requirement of partial coverage for small satellite constellation in details. Based on the analysis of the key factors effect on the constellation performance, the optimal model is given by choosing the appropriate parameters with some constraints. For the design of different satellite planes, the potential and characteristic of constellation optimization are stated through the comparison between two orbit surface and three orbit surface constellation with some a specific task. Whereafter simulation and analysis is done. The result shows that the optimal model provided herein is of theoretical meaning and practical application.
