In order to ensure the precision and reliability, this paper designs the GPS/Loran C/SINS/AHRS integrated system. In this integrated system, the self-adaptive federated Kalman filter is introduced to revise strap-down inertial navigation system; the heading angle attitude and heading reference system is used to ensure the convergence of heading angle; and the coordination transformation for Loran C is applied to eliminate the constant error of Loran C.
针对导航精度及可靠性,设计了GPS/罗兰C/SINS/AHRS组合导航系统,该组合导航采用了自适应联邦卡尔曼滤波的方法,通过闭环形式校正SINS,并用姿态航向参考系统代替捷联惯性导航系统输出的航向角以保证航向角的收敛,同时对罗兰C的测量值进行坐标变换以消除由于坐标系不同而带来的常值误差。
