WebIn Section 2, the global DGPS positioning and current systems are described. Sections 3 and 4 provide two different global DGPS processing methods based on code and carrier phase observations along with numerical results. The conclusions are given in Section 5.

WebIn static GPS/GNSS surveying, the receivers is motionless for a time, usually a relatively long occupation. If a static GPS/GNSS control survey is carefully planned, it usually progresses smoothly. The technology has … Web4.0. OBSERVATION GUIDELINES FOR ESTABLISHMENT OF BASE POINT / POINTS 4.1. The PCPs or Base points will be established by simultaneous observation along with two reference points provided by CGSAC by trilateration method in Static mode of observation. The DGPS observation on PCP will be undertaken at 05 seconds epoch 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).
