GPS／DR组合测姿自适应算法研究

GPS/DR Integrated Attitude Determination Adaptive Filtering Algorithm

本文提出GPS位置误差估计算法及状态误差协方差阵和观测误差协方差阵自适应调节算法，有效地提高了GPS／DR组合导航测姿的精度。

In order to improve the precision of stance measure by GPS/DR integrated navigation effectively, the algorithm of estimating the GPS position error and the adaptive algorithm of regulating state error and observational error matrices is discussed in the paper.
