给出了利用星敏感器测量信息自主确定地球静止卫星位置的方法,利用不同精度的星敏感器测量数据和不同控制精度的卫星姿态测量数据,可以直接计算卫星位置。同时又对测量数据应用卡尔曼滤波进行卫星位置计算仿真,比较两种处理结果的精度。仿真结果表明,提出的方法可以实时自主获取静止卫星的轨道位置,满足静止卫星定点的不同精度需求。
The method to determine the position of the geostationary satellite autonomously by using the satellite sensor measurement information is given. The satellite position can be directly calculated by using the satellite sensor measurement data with different accuracy and the satellite attitude measurement data with different control accuracy. At the same time, the Kalman filter is applied to the measurement data to simulate the satellite position, and the accuracy of the two processing results is compared. The simulation results show that the proposed method can acquire the orbital positions of the stationary satellites in real time and satisfy the requirements of different precision of the stationary satellites.
