低轨卫星倾斜轨道设计及优化

根据有效载荷性能和任务需求对低轨卫星的倾斜回归圆轨道设计进行了研究,以升交点赤经为参数,对1个回归周期内特定目标的覆盖性能指标进行了优化。算例表明:卫星对地面目标点的覆盖率可达0.977 5。如需对多个目标点或目标区域进行观测,可在此基础上增加目标点再作优化设计,以获得最佳覆盖性能。

The Orbit Design and Optimazation for Low Earth Orbit Satellite

According to the performance of the payload and mission requirement,the inclination regression circular orbit design of lower earth orbit satellite was studied in this paper.The coverage for certain object in one regression cycle was optimized when the longitude of ascending node optimal was served as the parameter.The example showed that the coverage of the satellite to the ground point of the target was 0.977 5.If the observation to the several target points or target area was required,the optimization would be done to gain the optimal coverage while the target points were added in the optimization.
