一种考虑摄动影响的星座构型稳定性设计方法

研究了星座构型稳定性设计方法,通过分析在长期摄动因素影响下星座各卫星轨迹偏移量,采用卫星初始参数偏置补偿原理,提出星座整体偏移思想。结合数据拟合方法,对多种摄动整体影响结果进行拟合调整,设计相应的调整方案,以消除卫星轨道在长期摄动因素下产生的偏差,保持了星座构型稳定性。在获得相应的参数调整量后,选取最为合理的设计方案,使卫星构型因摄动影响而调整所需要的能量尽可能小。

A Novel Design Method for the Constellation Configuration Stability Considering the Perturbation Influence

The design method for the constellation configuration stability is studied. By analyzing the satellite trajectory offsets under the effects of long-term perturbation factors, the idea of overall constellation offset is proposed by adopting the principle of satellite initial parameter offset compensation. Combined with the data fitting method, the overall affected results of various perturbations are fitted and adjusted, and the corresponding adjustment scheme is designed, so that the deviation of the satellite orbit under long-term perturbation factors can be eliminated and the constellation configuration stability can be maintained. After the corresponding parameters have been adjusted, the most reasonable design scheme is selected, so that the energy required for the satellite configuration adjustment due to the perturbation effects could be as small as possible.
