| 摘 要： | GPS天线存在相位中心偏差,在高精度测量中必须对其进行补偿改正。本文针对GPS天线的两种改正模型:相对改正模型和绝对改正模型,在讨论了它们所具有的相同改正办法的基础上,分析了它们在测定方法上存在区别,最后通过一个算例分别研究了这两种模型对GPS测量解算精度的影响,得出了一些有意义的结论。

| Abstract: | GPS antenna exists phase center deviation, it must be corrected in high-precision GPS survey. There are two models used in antenna phase center offset: relative phase center model and absolute phase center model. Based on the same geometrical models , the paper analyzes their difference on metrical and corrective methods and a practical example was given to research the influence of model change on GPS data processing precision, some helpful conclusions were given in the end. |
