说明：  文针对 INS/ GPS舰船用组合导航系统进行 研究,为提高 INS 误差的修正精度,采用高精度 GPS姿态测量系统为 INS提供外部修正信息,以增 强系统的观测量.在对自适应卡尔曼滤波器分析的 基础上,提出了一种新的基于新息估计的自适应卡 尔曼滤波算法,以解决外部量测噪声出现不确定强 度变化问题.
(Text for the INS/GPS navigation system for ships to study, to improve the accuracy of INS error correction, using high-precision GPS attitude measurement system for the INS amended to provide external information to enhance the system of observations. In the adaptive Kalman filter Based on the analysis, a new interest rate is estimated based on the new adaptive Kalman filter algorithm to solve the external uncertainties, the measurement noise intensity change.)
