摘要
针对高动态 GPS 导航不易确定系统噪声和观测噪声的特点和在实际应用 Sage 算法估计噪声一阶矩时出现一个小误差影响结果准确度的问题,提出了基于 Sage 自适应卡尔曼滤波算法的改进方法和同步并行Sage 自适应滤波结构,大大提高了滤波的精确度和准确度.
It is difficult to know noise of system and espial when kalman filter in GPS dynamic navigation,and it results in accuracy of navigation result when Sage filter is used in normal work.So a adaptive kalman filter based on Sage filter and a method of parallel filter structure of adding a concomitant filter is present in the paper,which makes accuracy and adaptive capability of filtering result improved.
