Webshore marks if visual fixing methods are to be employed. Decide on how and where the chosen navaids will be calibrated and whether re-calibration will be necessary during the course of the survey. Most modern surveys use some form of GPS for control ashore and afloat. Where DGPS is used for control afloat it must be validated. WebThe DGPS survey is a very critical element in this methodology. The high- resolution satellite imagery is geo-coded using precise ground control survey. The GPS coordinates for each ground control point (GCP) are collected and processed in a precise manner. The sequence of steps of the DGPS survey is given below: Webof the RTK method of Differential GPS (DGPS) operation using a local base station and a rover with an onsite radio frequency (RF) telemetry link (2). This report extends that concept using new GPS equipment, RF modems and a survey unit. Section 1 provides background information on DGPS and the application of RTK operation. fls alloc
