一种新型陆标敏感器算法的研究

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。

A new Algorithm of Landmark Sensor

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.
