全球定位系统中观测到的载波相位取决于发射机和接收机天线的方向以及视线的方向。根据圆极化波的特性，推导出两个等效的解析公式。用模拟来评估校正的幅度。最后给出了一个GPS实验的结果，说明了相位校正的效果。本文给出了一个用接收机和发射机在地心所对的立体角表示的差分测量值的定性计算公式。
The observed carrier phase in the Global Positioning System depends on the orientation of the antennas of the transmitter and the receiver as well as the direction of the line of sight. Two equivalent analytic formulas are derived for the correction based on the property of circularly polarized wave. The magnitude of the correction is evaluated with a simulation. Result from a GPS experiment is shown for the effect of the phase correction. A general formula useful for qualitative evaluation of the differenced measurements is given in terms of the solid angles subtended at the center of the earth by the receivers and transmitters involved.
