摘要
为提高天体参数测量和计算的精度,尽可能地减小误差。应用卡尔曼滤波稳健估计的原理与方法,在自适应卡尔曼滤波器的基础上进行加权运算。计算机仿真结果表明,同其它卡尔曼滤波方法相比较,该方法较好地抑制了参数计算中的误差,提高了天文导航定位数据的可信度。
In order to improve the precise of the measurement and calculation of celestial parameters,theory and method of Kalman filter solidity estimate was introduced.Based on the adaptable Kalman filter,this method decreased the error of celestial parameter,and improved the reliability of data of celestial navigation and position,compared with general Kalman filter and adaptive filter.
