  DGPS What is DGPS? DGPS (Differential Global Positioning System) survey is a surveying method that uses a combination of GPS and a reference station to improve the accuracy of GPS data. In a DGPS survey, a reference station is set up at a known location and the GPS receiver at the survey location takes measurements from both the GPS satellites and the reference station. The reference station then uses these measurements to calculate and transmit correction factors to the GPS receiver, which are used to improve the accuracy of the GPS data. Why does it required ? DGPS survey is required in a variety of applications such as mapping, navigation, and land surveying. It is particularly useful in cases where high accuracy is required, such as in construction and engineering projects, where even small errors in position can result in significant cost or safety issues. It is also used in marine navigation, where safety and navigation accuracy is critical. In addition, DGPS survey is also...
