| 摘 要： | 捷联惯导系统(SINS)在航空矢量重力测量中的基本功能是比力测量,但是纯惯导不能满足精度要求,因此通常采用卡尔曼滤波SINS/DGPS组合导航来提高比力测量的精度。通过误差状态可观性分析设计一种新的降阶滤波算法,该算法使得比力测量分系统的概念更加明晰,并通过仿真验证新算法的正确性。

| Abstract: | The function of SINS in airborne vector gravimetry is to measure the specific force,but standalone SINS can not satisfy the precision,so usually SINS/DGPS integrated navigation using Kalman Filtering is applied to improve the precision.In this article,a new reduced order filtering algorithm is designed through observability analysis,the algorithm makes the concept of specific force measurement more clearer,and the correctness of this new algorithm is validated through simulation. |
