| 摘 要： | 在简要介绍了DGPS基准站控制网建立的特点及作业流程后，着重讨论了此类GPS控制网建立过程中几个主要技术问题的解决方法，即用坐标转移法进行偏心观测、用尺度强制约束法或投影面重新选择法处理投影变形和内业平差。工程实践表明，上述问题的有效解决对DGPS基准站坐标的准确测定发挥了良好的技术支撑作用。

| Abstract: | The features and operation procedures in establishing DGPS datum stations framework are briefly introduced at first. Then some technical questions are discussed in detail, such as the reduction procedure of GPS offset observation, the processing of projective deformation and the adjustment optimal process. The engineering practice indicates that the research can effectively support the determining of DGPS datum station. |
