摘要(Abstract)：

针对天线相位中心改正影响GPS数据解算以及处理软件不能识别接收机天线类型的问题,该文提出了利用近似型号的天线进行数据处理的方法。首先利用IGS站精确确定天线相位中心改正对数据解算造成的影响,再利用IGMAS站验证方法的可靠性。该文选取部分IGS、IGMAS站的数据,利用GAMIT软件进行试验并分析。结果表明,当不使用天线相位改正模型时,增大了单天基线解的NRM_S值,并增加15.5%的基线误差,对精密定位能带来平均2cm的影响;当将处理软件不识别的天线换成近似能识别的天线时,基线解效果要比不使用天线改正效果好,水平和垂向的定位精度均在3.9mm左右,比使用原装能识别天线的定位精度稍差。该方法既保证了精度,也较为简单快捷。
