摘　　要：稳定的构型是星座发挥其正常功能的基础。首先结合卫星在轨运行动力学环境,回顾了地球重力场模型、日月引力模型、大气模型与太阳光压模型的发展,在此基础上介绍了大气模型和太阳光压模型的在轨修正技术。其次,阐述了星座构型保持的必要性与可行性,总结归纳了摄动补偿法、预先设计法、全局优化法、阻力差分法与极限环保持法等构型保持方法,对比了绝对保持与相对保持的控制基准与方法特点。最后,展望了针对不同高度的低轨(low Earth orbit,LEO)星座构型保持,旨在为LEO星座的构型保持策略设计提供参考。Stable configuration is the basis for constellation to perform its normal function.Firstly,combined with the dynamic environment of satellites on-orbit,the development of Earth gravitational field model,lunisolar attraction model,atmospheric model,and solar radiation pressure model are reviewed.On this basis,the on-orbit revision techniques of atmospheric model and solar radiation pressure model are introduced.Secondly,the necessity and feasibility of constellation configuration maintenance are illustrated,and the configuration maintenance methods such as perturbation compensation method,pre-design method,global optimization method,differential drag method,and limit cycle keeping method are summarized.Thirdly,absolute maintenance and relative maintenance are compared from control reference and method characteristics.Finally,the configuration maintenance of low Earth orbit(LEO)constellation for different orbital height is prospected,which provides a reference for the configuration maintenance of LEO constellation.
