摘要
讨论了GPS单点伪距定位的特点 ,然后利用测距测向仪来弥补GPS导航的不足以及提高导航精度 ,并给出了确定初值的一种迭代算法 ,最后提出了八状态的卡尔曼滤波器。
The navigation via integrated GPS/direction and distance surver set is mainly discussed in this paper. An initial solution algorithm to reduce the possibility of diffusion of original Kalman filter and a 8 state extended Kalman filter have been proposed by the authors,and the linearized measurement and dynamic equation have been derived in this paper.
