| 摘 要： | 通过对SINS/OD组合系统和SINS/MM组合系统的可观测性进行初步的定性分析。利用可观测分析的基本方法对SINS/MM/OD组合导航系统在不同机动条件下的可观测性进行了详细的分析。仿真结果表明:SINS/OD/MM组合导航系统的姿态、位置、速度均可观测;系统各状态可观测程度与载车行驶轨迹有很大关系。当载车做大的机动转弯时,能有效地提高系统方位误差角的可观测性。

| Abstract: | This article through to the SINS/OD system and SINS/MM system observability is preliminary qualitative analysis, using the observed the basic analysis method of the SINS/MM/OD integrated navigation system in different maneuver under conditions of observability is analyzed in detail. The simulation results show that: the SINS/OD/MM integrated navigation system attitude position speed can be observed; the observable degree and loading vehicle running track has the very big relations, when the car carrying big motor turning, can effectively improve the system position error angle observability. |
