| 摘 要： | 提出了一种差分GPS定向校准方法，即利用差分GPS测得固定站和运动站的坐标（WGS-84），应用计算模型求出运动站相对固定站的大地方位角，再与由一等天文点计算给出的大地方位角进行比对。给出了计算模型，试验设备，试验方法和试验数据，验证了思路的正确性和可行性。

| Abstract: | A calibration method for the difference GPS direction is proposed. The coordinates（WGS - 84） of the fixed station and the floating station are measured by using of difference GPS. The earth azimuth of the floating station opposite to the fixed station is computed by the computational model. The earth azimuths computed are compared with the high-class astronomical station. The computational model, the experimental equipments, the experimental method and the experimental data are given. The correctness and the feasibility are verified. |
