用于对地观测定位的编队飞行卫星群轨道构形设计

编队飞行卫星群是一组小卫星,它们具有短的相对距离、相等的轨道半长轴和微小差别的其它轨道要素,它们形成相互伴随运动,并且具有一定的构形。提出将编队飞行卫星群的轨道设计技术应用于对地观测定位卫星系统中。根据设想的要求,针对由四颗伴随卫星围绕基准卫星(或一个虚拟的中心)飞行的轨道设计案例,初步分析了编队飞行卫星群的构形保持,地球引力和大气阻力的摄动影响等问题。

Orbit configuration design of formation flying satellites to be used for earth observing and positioning

Formation Flying Satellites is a team of small satellites.They share short relative distance,equal semi-major axis of orbit and other orbital elements with tiny differences.They keep accompanying flight mutually with a certain configuration.The relative trajectory with respect to the "core satellite" is an ellipse in datum orbit coordinate frame.This paper presents application of the technology of formation flying satellites into the Earth observing and positioning satellite system,and analysis of perturbation effects of Earth gravitation and atmospheric drag etc.generally based on the case of orbit design of four accompanying satellites flying around the reference one or a virtual center according to the assumed requirement.
