摘要： 给出一种选择双自旋通信卫星在任意轨道飞行时最佳通信姿态的计算方法。根据测得的轨道平根数及姿态值,应用微机可对卫星轨道参数、星下点轨迹、地面站跟踪条件、姿态测量参数、卫星的太阳角、对应于各测控站的卫星测控天线增益、对应于各通信站的通信天线增益和波束中心地面轨迹进行快速计算,给出飞行试验需要的全部卫星飞行参数。根据飞行试验中对卫星姿态选择的附加限制,可以选择出最佳通信姿态,保证获得最长的通信时间。

Abstract: This paper gives a way to select the optimum attitude of dualspin communication satellite in any operation orbit.Based on the measuredorbit elements and attitude all the parameters needed to flight test could becomputed sapidly by using a microcomputer.According to the additionalrestriction on the selection of the attitude a optimum attitude could becomputed to ensure longer communication duration.
