| 摘 要： | 为了尽可能估计出捷联惯导系统中惯性仪表的误差,建立捷联惯导系统误差方程和量测方程,运用传递对准技术,构建了速度匹配方式下的Kalman滤波器模型,研究了线加速和拐弯机动下对惯性仪表误差估计的影响,并对计算机仿真结果进行比较分析,仿真结果表明:线加速情况下可以提高陀螺漂移误差的估计精度,拐弯情况下可以提高加速度计偏置误差的估计精度。

| Abstract: | In order to estimate inertial instrument errors of SINS, dynamic and measure equations of SINS are established .The Kalman filter model of transfer alignment using velocity matching method is given in the paper. A study on inertial instrument errors estimation with axial acceleration and circular maneuvers and analysis of simulations are carried out .The simulation results show that axial acceleration maneuver enhance the estimation performance of the gyro drift rate errors and circular maneuver enhance that of the accelerometer bias errors. |
