Differential Global Positioning Systems (DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS for GPS can increase accuracy by about a thousandfold, from approximately 15 metres (49 ft) to 1–3 centimetres (1⁄2–1+1⁄4 in). DGPSs consist of … See more When GPS was first being put into service, the US military was concerned about the possibility of enemy forces using the globally available GPS signals to guide their own weapon systems. Originally, the government … See more A reference station calculates differential corrections for its own location and time.

WebIt will post process GPS observations to calculate precise DGPS positions of antenna and rest of locations. Once the software has precise location it can calculate the baselines and actual elevation and azimuth at those points. The final output of the software is a correction horizontal plane and azimuth correction number. 3 FUNDAMENTALS OF DGPS WebDgps concept. 15-meter nominal GPS accuracy to about 10 cm in case of the best implementations. Differential Global Positioning System (DGPS) is a method of providing differential corrections to a Global Positioning System (GPS) receiver in order to improve the accuracy of the navigation solution.
