摘要(Abstract)：

针对全球卫星导航系统(GNSS)卫星端相位小数周偏差(FCB)难以有效分离而导致模糊度固定较为困难的问题，该文通过构建基于原始频率观测值上的双频非组合FCB估计模型，实现了全球定位系统(GPS)、北斗二号(Beidou-2,BDS-2)和北斗三号(Beidou-3,BDS-3)卫星端FCB精确估计，并在此基础上实现了GPS、GPS/BDS-2和GPS/BDS-2/BDS-3不同系统融合的静态和动态非组合精密单点定位(PPP)模糊度固定解。结果表明，GPS FCB稳定性最优，BDS-3 FCB稳定性略差于BDS-2;相对于单GPS和GPS/BDS-2系统，GPS/BDS-2/BDS-3融合的PPP固定解在定位精度、收敛时间和模糊度固定率等方面得到显著改善。
