摘要： 针对已知推力器在地球静止轨道卫星上的安装信息和已知推力器的工作信息,对推力器作用力进行建模,分析计算推力器在不同工况下工作对卫星轨道的影响;统计在轨卫星推力器工作对轨道的影响效果,并与计算结果分析进行比较,说明在轨道外推模型中加入推力器作用力的修正,可以有效地改善轨道外推的精度。

Abstract: The analytical model of the thrusts was built based on its assembly and the operation information in geosynchronous orbit.The impact of the thrust to the operating orbit in various conditions was analyzed.The impact effect of the thrust on the orbit was evaluated and the analytical results were compared.In addition,the thrust extrapolate modeling modification was also presented,which improved the orbital extrapolate precision.
