| 摘 要： | 利用厂商模型、MGEX模型和ESA模型对BDS卫星天线相位中心偏差进行改正，结果表明，3种模型对BDS精密单点定位精度均有所提升，其中，水平方向提升1～2 cm，高程方向定位精度由1 dm提升为厘米级，ESA模型优于另外两种模型。利用GPS接收机天线相位中心偏差改正值对BDS接收机天线相位中心偏差进行改正，其精度改善情况随天线类型的不同而存在差异，水平方向精度影响为毫米级，高程方向与天线类型有关，精度影响最大可达厘米级。

| Abstract: | In this paper, the manufacturer's model, MGEX model and ESA model are used to correct the antenna phase center offsets and variations of BDS satellites in precise point positioning. The results show that the three models improve the accuracy of BDS precise point positioning, with an improvement of 1~2 cm and from 1 dm to centimeter level in the horizontal and vertical directions. Meanwhile, the ESA model is better than the other two models. For the receiver phase center offsets and variations, the BDS is corrected by the GPS correction model. Compared with the uncorrected model, the accuracy improvement varies with antenna types, which can be millimeter level in the horizontal direction, whereas it can be centimeter level in the vertical direction. |
