Sage_Husa自适应滤波算法在捷联组合导航系统中的应用
Application of Sage _ Husa Adaptive Filter to Integrated Navigation System
摘要
Abstract
In view of the application of integrated navigation system, the paper presents a Sage _ Husa adaptive filter algorithm based on the existing methods. The pre-knowledge of system mathematic model and noise statistic was required when using Kalman filter, but they were unknown, approximate or known partly in actual system. The estimated error value of system state was increased when an inaccurate model and statistic of noise were applied. The simulation results show that the Sage _ Husa adaptive filter has high convergence speed, high effectiveness and accuracy and its precision is similar to that of conventional Kalman filter.关键词
