摘要
在进行位置势导航滤波时 ,观测值的方差阵是影响导航滤波精度的重要因素。对于海上运动的舰船 ,由于观测值是动态变化的。提出了一种无需设置参考系统求解观测值方差阵的动态方法。
The observation covariance matrix is a important factor of influence on navigation precision in position potential navigation.As to the marine navigated vessel,observation value is dynamic and various.So the author give a dynamic way of solution to observation covariance,but also the way need not set up reference system.
