Abstract:

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.

Key words: low Earth orbit (LEO) constellation, configuration maintenance, revision on-orbit, perturbation compensation, differential drag, limit cycle
