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.
