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.

WebOct 13, 2024 · Using SBAS services improves the accuracy of receivers, but not to the same degree as a local base station. When using DGPS, the accuracy of position measurements often improves to tens of centimetres, say around 40 cm. DGPS that is achieved through SABS is often sub-metre accurate, somewhere in the range of 50–60 cm.
