摘要(Abstract)：

为了减小当前北斗坐标参考框架基线解算中部分接收机天线相位中心未知对定位精度的影响，在天线相位中心偏差和天线相位中心变化定量分析的基础上，设计了采用天线实际GPS PCC改正模型或相似BDS PCC改正模型进行替代的解算策略。通过国家卫星导航定位基准站框架网实测解算验证，结果表明：两种方案基线解算时NRMS值均低于0.25,基线相对重复率达到10~(-8);以GPS天线相位改正模型替代方案与已知的BDS天线相位改正模型解算结果比较，N、E、U方向差值分别为3、5、5 mm;采用近似BDS模型替代方案与已知的BDS天线相位改正模型解算结果比较分析，N、E、U方向差值分别为3 mm、7 mm、2 cm。在北斗接收机天线相位中心改正模型未知时，使用GPS天线模型进行替代具有一定的可行性。
