This article examines global navigation satellite system (GNSS) phase windup, which we define to be the combined effects of 3-D rotation and antenna phase patterns on carrier-phase measurements. Specifically, phase windup equations are presented for antennae with spatially varying phase patterns, for instance, phase patterns defined as a function of the satellite line-of-sight direction, as might be characterized by azimuth and zenith angles. We observe that a description both of the geometric rotation and, also, of the antenna phase pattern are needed to accurately evaluate phase windup for a general antenna. Furthermore, we show that there is not a unique approach for computing phase windup; in fact, correctly computing phase windup requires adjusting the model to match the calibration method used to obtain the antenna phase pattern.

几何旋转和天线校准模式对 GNSS 相位饱和的综合影响


本文研究了全球导航卫星系统 (GNSS) 相位饱和，我们将其定义为 3D 旋转和天线相位模式对载波相位测量的综合影响。具体而言，提出了具有空间变化相位图的天线的相位饱和方程，例如，相位图被定义为卫星视线方向的函数，可以通过方位角和天顶角来表征。我们观察到，为了准确评估一般天线的相位饱和，需要描述几何旋转和天线相位图。此外，我们表明没有一种独特的方法来计算相位饱和；事实上，正确计算相位饱和需要调整模型以匹配用于获取天线相位图的校准方法。
