摘　　要：本文首先分析了采用卫星位置速度和姿态测量矩阵两种方法进行天线相位中心偏差改正的差异；然后运用2006年1月4日的GRACE—A卫星实测数据，计算了两种方法对改正值和定轨结果的影响。结果表明：（1）两种方法对改正值和定轨结果的影响与天线在星体坐标系中的位置有关；（2）利用两种方法计算的角度之差互检，可以探测姿态测量粗差。Firstly, the differences of two methods for antenna phase center offset correction, one using position and velocity and the other using attitude measurement matrix are analyzed. Secondly, the influences of the two methods on the corrections and orbit determination are calculated with measured data of satellite GRACE-A on January 4, 2006. The results show that the influ- ence of the two methods on the corrections and orbit determination has relation to the location of antenna in the satellite coordinate system, and the differences of the angles computed with the two methods can detect the gross error of the attitude measurement.
