| 摘 要： | 提出一种利用重力异常信息校正惯导系统的方法按照一定方法将重力实测数据和数字重力图进行相关分析和匹配以得到最优路径,再用位置误差对惯性器件误差进行扩展Kalman滤波估计,最后对惯导系统的导航状态进行修正,得到最优导航状态。

| Abstract: | A method of revising inertial navigation system by using gravity abnormal information is introduced.Actual gravity data and digital gravity map were analyzed correlatively and matched by certain method in order to get optimal route.Inertial equip error was estimated by extended Kalman filter through position error.In the end ,the navigation status of inertial navigation system was revised so that optimal navigation status was acquired. |

| Keywords: | inertial navigation matching extended Kalman filter |
