摘要： 摘要：针对多颗MEO导航卫星太阳翼展开后产生比较明显的干扰力矩，对卫星稳定控制产生了一定影响的现象，本文根据动力学模型、姿态、角速度和飞轮转速变化，给出了干扰力矩计算方法，并结合多颗卫星在轨遥测数据进行计算，得出放气期间产生的干扰力矩.通过使用此干扰力矩进行仿真得出，卫星模拟器结果和在轨表现基本一致.此研究有助于优化卫星飞控流程，并指导卫星放气孔设计.

Abstract: Abstract： In view of the phenomenon that the solar wings of multiple MEO navigation satellites have obvious interference torque after deployment, which has certain influence on the stability control of the satellite, this paper presents the calculation method of interference torque according to the dynamic model, attitude, angular velocity and the change of reaction wheel speed. According to the telemetry data of several satellites in orbit, the interference moment produced during deflation is obtained. Using this interference moment for simulation, the results of the satellite simulator are basically the same as those in orbit. This study is helpful for optimizing the process of satellite flight control and guiding the design of satellite exhaust hole.
