摘要

提出了基于自适应滤波的天文/惯性/北斗组合导航算法。分析了卫星几何构型对北斗导航系统定位精度的影响,提出了基于卫星可见星数目及卫星几何构型的自适应滤波方案;针对卫星拒止情形,设计了天文辅助的惯性/北斗紧组合导航方案;基于树莓派3B,构建了组合导航系统样机,通过动态试验进行测试分析。结果表明,提出的自适应滤波算法整体性能优于单独采用北斗导航系统及非自适应滤波算法性能,导航结果验证了组合导航系统样机硬件平台及导航算法的正确性及工程实用性。
        Astronomical/SINS/BD integrated navigation algorithm with adaptive filtering is put forward.Firstly,we analyzed the influence of satellite geometry on the positioning accuracy of BeiDou Navigation satellite system.Based on this,an adaptive filtering scheme based on the number of visible stars and satellite geometry of BeiDou satellite is proposed.For the case of BeiDou navigation satellite rejection,we designed the astronomical aided SINS/BD tight combination navigation scheme.Finally,based on the Raspberry Pi 3 B embedded system,the prototype of the SINS/BD integrated navigation system based on astronomical aid was constructed,and real-time test analysis was carried out through dynamic experiments.The experimental results showed that the adaptive filtering algorithm studied in this paper has a good applicability to the hopping of the information of the Big Dipper.The hardware platform and navigation algorithm of the integrated navigation system was verified by the navigation results.
