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。
通過分析北鬥衛星定位導航繫統和慣性導航繫統的優缺點,設計一種基于北鬥/INS組閤導航的繫統數學模型。將北鬥衛星定位導航繫統和 INS的信息進行組閤互補,以卡爾曼濾波作為信息融閤算法,選擇間接法反饋校正模式設計組閤繫統,推導齣組閤導航繫統的狀態方程和量測方程,併根據組閤導航繫統的數學模型,對組閤繫統進行瞭跑車試驗。試驗結果錶明,北鬥/INS組閤後的導航繫統相對獨立導航繫統具有更高的精度。

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.
