摘　　要：载波相位差分GPS动态测量是近几年发展起来的定位新技术，可用于大比例尺测图、港口和航运测量、道路施工测量等精密定位中。文中就载波相位差分GPS定位中的几个问题进行了论述。它们是：差分GPS定位技术的比较，准载波相位差分与载波相位差分的性能与比较。最后，为用户选购和应用提出了参考意见。DGPS positioning is a new technology developed in the recent years. It can be used in the area of surveying and mapping, such as large scale mapping, harbor and channel surveying, high-way constructions etc. Some knowledges in using DGPS are described in this paper. They are: the comparison among DGPSs, the performances of carrier phase DGPS and psudo-carrier phase DGPS. Finally, some suggestions for user to purchase and apply the DGPS are given.
