北斗/INS组合导航在某型装备中的应用设计

摘要

According to analysis advantages and disadvantages of BeiDou satellite positioning navigation system and INS system, design system mathematical model based on BeiDou/INS integrated navigation system. Carry out composition complementary of BeiDou satellite positioning navigation system and INS information, use Kalman filter as information blend algorithm, choose indirect method to feedback correct mode and design integration system, deduce state equation and measurement equation of integrated navigation system. According to mathematical model of integrated navigation system, carry out running test of navigation system. The test results show that the BeiDou/INS integrated navigation is higher precision than independent navigation system.%通过分析北斗卫星定位导航系统和惯性导航系统的优缺点，设计一种基于北斗/INS组合导航的系统数学模型。将北斗卫星定位导航系统和 INS的信息进行组合互补，以卡尔曼滤波作为信息融合算法，选择间接法反馈校正模式设计组合系统，推导出组合导航系统的状态方程和量测方程，并根据组合导航系统的数学模型，对组合系统进行了跑车试验。试验结果表明，北斗/INS组合后的导航系统相对独立导航系统具有更高的精度。
