摘要
提出一种组合应用三轴磁强计信号与太阳电池阵列信号,在双矢量定姿的基础上,结合样点卡尔曼滤波(UKF)估计算法,连续输出六维姿态信息的姿态估计方法。数值仿真结果表明:两种测量信息有效组合时,精度水平可以满足皮卫星任务要求。
A method of integrating the measurements of a three-axis magnetometer and the body-mounted solar panel array is introduced in this paper. The unscented Kalman filtering (UKF) , which is a nonlinear state estimating algorithm, is selected to fuse two kinds of measurements. Both precisions can meet the requirements of pico-satellite.
