摘要
GPS天线相位中心改正是GPS精密定位的一个误差源,本文对GPS天线相位中心的相对、绝对天线相位中心改正模型进行了分析,同时研究了天线相位中心相对、绝对天线相位中心改正对精密单点定位的影响,研究发现二者对精密单点定位在平面方向吻合的很好,但高程方向上具有较大的差异,建议采用IGS正在使用的绝对天线相位中心改正模型。
GPS antenna phase center is an error source of GPS precision positioning.This article has analyzed the relative and absolute correction model of GPS antenna phase center and its effect on Precise Point Positioning accuracy.The result showed that both were in good agreement with Precise Point Positioning in horizontal direction,but there was a big difference in elevation direction.The paper suggested to adopt the absolute correction model of antenna phase center being used by IGS.
