卫星编队飞行具有广阔的应用前景,为此应用轨道根数研究卫星编队飞行的相对运动,得到了精确的相对运动轨迹。对轨道共面、轨道不共面,小偏心率椭圆轨道(包括圆轨道)、大偏心率椭圆轨道等情况进行了对比,对各种可能出现的轨道构形进行了归类。研究表明:卫星编队的条件是轨道半长轴相等,相对轨道构形依赖于中心卫星与伴随卫星的相对轨道根数,而与中心卫星的轨道根数无关。这些结论为编队飞行的任务设计提供了理论依据。
Satellite formation flying has broad application prospects. Therefore, using the number of orbital roots to study the relative motion of satellite formation flying, accurate relative motion trajectories are obtained. Comparisons are made between the orbital coplanar, the orbital non-coplanar, the small eccentricity elliptical orbit (including the circular orbit) and the large eccentricity elliptical orbit, and the various possible orbital configurations are classified. The results show that the conditions of satellite formation are that the orbital semi-major axes are equal, and the relative orbital configuration depends on the relative orbital root number of the central satellite and the accompanying satellite, but independent of the orbital root number of the central satellite. These conclusions provide theoretical basis for the mission design of formation flight.
