摘要
为分析GPS与QZSS重叠频率间组合定位的兼容性,文中基于自测试5 km短基线实测数据,分析了QZSS系统对GPS重叠频率短基线相对定位精度的影响。经研究发现,QZSS能有效增加GPS的卫星可见数和改善卫星空间几何构型,QZSS能一定程度上提升GPS重叠频率短基线相对定位精度,对3D方向定位精度提升量在10%~15%之间。
In order to analyze the compatibility of the combined positioning between GPS and QZSS overlapping frequency,in this paper,based on self-tested 5 km short baseline measured data,the influence of the QZSS system on the relative positioning accuracy of GPS overlapping frequency short baseline was analyzed.Research found that the visible number of GPS satellites could be increased effectively by QZSS and the spatial geometric configuration of the satellite was improved.Relative positioning accuracy of GPS overlapping frequency short baseline could be improved by QZSS to a certain extent,and 3D orientation positioning accuracy was improved by 10%to 15%.
