DGPS surveying is a relative positioning technique which employs two (or more) receivers simultaneously tracking the common satellites to provide positional corrections to GPS signals. It uses known position of Ground Network and adjust GPS signals in real time to eliminate errors. The base receiver, is set up over a point with precisely known coordinates such as a survey monument (Benchmark). The remote receiver, is set up over a point whose coordinates are unknown. This type of survey is primarily used to create control point where no control exists to very high accuracies.
