摘　　要：分析了中国境内IGS跟踪站磁偏角大小;并按最大磁偏角对具有代表性的GPS接收机天线的天线相位中心偏差计算了对应的偏移量。结果表明,天线指北偏差对定位结果的影响达到了亚mm级。This paper analyzed the size of the magnetic declination of the international global navigation satellite system in China.And then,according the maximum magnetic declination of the typical GPS receiver antenna phase center deviation,the paper calculated the corresponding offset.The result shows that the antenna refers to the north deviation on the result of positioning has reached the sub millimeter level.

关 键 词：磁偏角 系统差 GPS 高精度
