摘　　要：为准确测出GNSS接收机天线相位中心垂向偏差,在超短基线静态相对定位的基础上,给出一种倾斜测量法。由卧轴多齿分度台提供标准的旋转角,将待测接收机天线倾斜多组角度,其余4台接收机进行同步静态观测,解算出待测天线的多组坐标;再根据几何关系得出绝对垂向偏差。该方法中配合的天线无需已知相位中心偏差。通过分析经不同的数据处理方法所得结果的差异,并与IGS发布的参考值进行比较,证实此方法测量精度较高,且有较好的可行性。On the basis of the relative positioning method,a new method is proposed to calibration the vertical offset of the antenna phase center.Field Tests were carried out.A Precise Angle Dividing Table with horizontal axis provides a standard angle to measure antenna tilted angles,with the remaining four receivers logging static observations simultaneously and finally get the coordinates of the antenna under test to fix the offset,then analyzed the different data processing methods and its differences,and compared with the IGS reference value,confirmed that this method has high accuracy and good practicability.
