静止轨道卫星远程交会策略设计

Far-Range Rendezvous Strategy Planning for Geostationary Orbit Satellites

针对静止轨道卫星在轨服务任务,提出一种4脉冲远程快速交会规划方法,可在5圈内完成远程交会。调相策略设计中,通过对基于近圆偏差方程的变轨规划策略进行改进,设计得到了3脉冲调相方案。首先,固定第1和第2调相脉冲执行位置,对3个调相脉冲的速度增量及第3调相脉冲的执行位置进行设计优化;再固定第1调相脉冲,对第2和第3调相脉冲的速度增量和执行位置进行再次优化。轨道面调整设计中,通过求解轨道面节线位置,采用单一法向脉冲进行轨道面修正。数学仿真校验了所提出方法的有效性。

A four-impulse far-range rendezvous strategy for an on-orbit servicing mission of geostationary orbit satellites is proposed, which ensures the far-range rendezvous can be completed within 5 revolutions. A three-impulse phasing scheme is designed by an optimal algorithms, which is based on the near-circular deviation equations. Firstly, using the fixed positions of the first and second phasing impulses, the velocity increments of the three phasing impulses and the position of the third one are optimized. Then, fixing the first phasing impulse,the velocity increments and positions of the second and third phasing impulses are optimized again. Through improving the classical optimal scheme based on the near-circular deviation equations, an excellent phasing performance is achieved. In order to modify the orbit plane, a vertical impulse is executed on the cross line between the two orbits. Finally, the efficiency of the far-range maneuver strategy is validated by a simulation.
