摘要
提出了一种基于信息融合的姿态确定方法用于姿态确定。利用星上的GPS接收机和磁强计两种敏感器的测量 ,基于广义卡尔曼滤波理论及信息融合理论 ,发展了基于此两种敏感器的全局最优融合估计算法 ,来确定卫星的姿态和姿态角速度。并对算法进行了设计和仿真 ,通过与单独使用 GPS确定姿态的算法进行对比分析 。
An attitude determination approach based on information fusion for attitude determination is presented. Using the two sensors of on board GPS receiver and magnetometer and based on extended Kalman filtering and information fusion theory, the global optimal fusion estimating algorithm which determinates the attitude and rate of satellites is developed. Designs and simulations are processed and contrasted to the algorithm using GPS only. Results show the advantage of this algorithm.
