摘要
分析了GPS和北斗区域系统在(55°S^55°N,55°E^180°E)区域内DOP值和RDOP值的分布特点,探讨了可见卫星数、基准卫星变化、基线长度和基线方向对两类精度因子值一致性的影响关系。实验结果表明:北斗系统在中长基线相对定位中应使用RDOP值进行预报和精度分析。
This paper analyzes the distribution features of GPS and BDS DOP and RDOP within the region （55°S-55°N,55°E-180°E）, and discusses the influence for the consisten- cy of double precision factor with the number of visible satellites, the changes of reference satellite, the baseline direction and baseline length. The experiment results show that it should use the RDOP to forecast and analysis the long baseline relative positioning with BDS.
