摘要

接收天线与卫星天线的极化不匹配会导致测量误差，需要对误差进行已知和补偿。分析了极化失配对全球卫星导航系统(GNSS)高精度应用性能的影响。通过对来自卫星天线的接收信号进行仿真，结果表明极化失配会导致功率损失和相位误差，对于高精度GNSS应用，相位误差在毫米级，高于可容忍残差。

Impact of Antenna Polarization Mismatch on High-precision GNSS Application

The polarization mismatch between receiver antenna and satellite antenna causes measurement errors, and the errors should be known and compensated. In this paper, the effect of polarization mismatch on the performance of global navigation satellite system (GNSS) high-precision application is analyzed. Through simulations of the receiving signals by receiver antenna that comes from the satellites antenna, it is shown that the polarization mismatch arise power loss and phase errors, for high-precision GNSS application, the phase errors is at millimeter level, which is higher than the tolerable residual.
