摘　　要：静止轨道共位卫星相对轨道的确定,对于多星共位任务是十分重要的。根据静止轨道的特性,推导了标准静止轨道定点经度坐标系下共位卫星的相对运动状态方程,提出了采用微波测距和比相测角法获取多颗共位卫星星间测量信息;利用自适应Kalman滤波进行了相对轨道估计。仿真结果表明,利用该算法能够获得较理想的相对位置精度,且自适应滤波解好于标准滤波解。The relative orbit determination of Collocation satellites is very important for geostationary collocation mission. The relative orbit motion equation in geostationary orbit coordinates were derived based on the charac- teristic of the geostationary from using microwave radar and angle measurement with wireless phase discrimination to measure the relative information. The adaptive Kalman filter was utilized for the estimation of relative orbit. The simulation results showed that the method in this paper would acquire high accuracy, and the result of adaptive Kalman would be better than standard Kalman filter.
