摘要: 针对日本准天顶卫星系统（QZSS）对北斗二号（BDS-2）和北斗三号（BDS-3）短基线相对定位性能的影响,本文基于国际GNSS服务（IGS）跟踪站组成的5 km和10km两条短基线,分析了QZSS、BDS-2、BDS-3不同组合短基线相对定位精度．经研究发现,QZSS能有效改善BDS-2和BDS-3卫星可见数与卫星空间几何构型,而BDS-2／BDS-3组合下的卫星可见数与卫星空间几何构型优于任一单系统．在定位精度方面,QZSS与数据缺失情况下BDS-3组合定位精度与BDS-2相当,同时QZSS能有效提升BDS-2和BDS-2／BDS-3相对定位精度,而BDS-3对BDS-2定位精度的提升要优于QZSS．Abstract: In view of the impact of QZSS on the relative positioning performance of BDS-2 and BDS-3 short baselines,this paper analyzes the short baselines of different combinations of QZSS,BDS-2 and BDS-3 based on the 5km and 10km short baselines composed of IGS tracking stations relative positioning accuracy.It is found that QZSS can effectively improve the BDS-2 and BDS-3 satellite visibility and satellite space geometry,while the satellite visibility and satellite space geometry of BDS-2／BDS-3 combination is superior to any single system.In terms of positioning accuracy,the combined positioning accuracy of BDS-3 and QDSS is equivalent to BDS-2 in the case of missing data.At the same time.QZSS can effectively improve the relative positioning accuracy of BDS-2 and BDS-2／BDS-3.while BDS-3 shows better performance than QZSS in improvement of positioning accuracy of BDS-2.
