SINGULAR VALUE DECOMPOSITION-BASED ROBUST CUBATURE KALMAN FILTER FOR AN INTEGRATED GPS/SINS NAVIGATION SYSTEM
Singular Value Decomposition Cubature Kalman Filter Integrated GNSS/SINS Navigation System Nonlinear Filter
2014/4/21
A new nonlinear robust filter is proposed in this paper to deal with the outliers of an integrated GPS/SINS navigation system. The influence of different design parameters for H∞ cubature Kalman filte...
INS/GPS 组合导航系统的本质是非线性的, 为改善非线性下INS/GPS 组合导航精度, 提出将一种新的非线性滤波cubature Kalman filter(CKF) 应用于INS/GPS 组合导航中. 为此, 建立了基于平台失准角的非线性状态模型和以速度误差及位置误差描述的观测模型, 分析了CKF 滤波原理, 设计了INS/GPS 组合滤波器, 对组合导航非线性模型进行了仿真. 仿真结果显...
