一种新型陆标敏感器算法的研究

A new Algorithm of Landmark Sensor

卫星姿态将直接影响卫星执行任务结果和在轨寿命,陆标敏感器可以从卫星遥感图像信息中获取卫星的姿态信息。提出一种新型陆标敏感器的算法,根据卫星计划拍摄的理论范围与实际图像范围的偏差,计算出卫星的侧滚、俯仰和偏航三种姿态偏差。该算法的优点在于能与实际任务相结合,在测量分析卫星姿态偏差的同时不影响卫星正常执行任务。

The attitude of a satellite has direct impact on tasks and life of the satellite. Landmark sensor acquires satellite attitude information from the remote sensing images. This paper presented an algorithm of a new landmark sensor. According to the warp between realtime images and planed extension, it can compute the satellite＇ s yaw angle, pitching angle, rolling angle. The advantage of the algorithm is that it can combine with the task of satellite without influence on the task.
