提出了一种基于扩展卡尔曼滤波(EKF)和增广量测的捷联惯导系统(SINS)自对准改进方案。蒙特卡罗仿真表明，该方法具有良好的方位对准效果，提高了方位姿态误差的收敛速度，降低了对陀螺偏差的敏感度。(C)2010年爱思唯尔·马森公司。版权所有。
An improved self-alignment scheme for strapdown Inertial Navigation System (SINS) based on the extended Kalman filter (EKF) and augmented measurements is proposed. Monte Carlo simulations show that the method provides good azimuth alignment, improved rate of convergence of azimuth attitude error and reduction in sensitivity to gyro biases.
