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。
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 helpfitl conclusions were given in the end.
