摘　　要：针对常规旋转天线法中旋转角度不准确以及天线相位中心具有随机性的情况,提出了利用均值法进行GPS接收机天线相位中心水平方向上偏差的检测和校正.该方法是将两台接收机安置在超短基线两端,固定其中一台接收机,将另外一台接收机天线均匀旋转,基线解算,计算旋转的接收机天线相位中心水平方向偏差大小.结合实例证明:新的检测方法快捷、简便,适合野外利用超短基线进行天线相位中心水平方向偏差的检测.In view of the inaccurate rotation angle of the conventional rotation antenna method and the random of the antenna phase center, the averaging method for detecting and correcting the horizontal deviation of antenna phase center of GPS receiver is proposed. The method is to place two receivers on both ends of ultra-short baseline, one receiver is fixed, and the other is rotated uniformly, then the baseline and the horizontal deviation of antenna phase center of the rotating receiver are calculated. Combined with the instance, it is proved that the new detection method is quick and simple, and suitable for the detection of horizontal deviation of the antenna phase center with the outdoor ultra-short baseline.
