摘要
在分析INS、GPS、CNS导航系统特点的基础上,建立了组合导航系统的误差模型,提出了一种基于联邦滤波器的INS/GPS/CNS的组合导航算法,采用平台失准角、INS与GPS的位置之差和速度之差作为观测量,对算法进行了仿真研究。仿真结果表明:通过校正惯导平台、消除导航参数误差,可以大大提高系统的导航精度。
By analyzing the characteristics of INS, GPS and CNS navigation systems, we construct an error model of integrated navigation system and propose a INS/GPS/CNS integrated navigation method based on federated filter, with platform error-angle as well as differences of position and velocity between INS and GPS as measurement. The simulation manifests the accuracy can be dramatically improved by rectifying inertial navigation platform and eliminating the error of navigation parameters.
