DGPS
Description:
“Differential Global Positioning System (DGPS) is an enhancement to the Global Positioning System that provides improved location accuracy, from the 15-meter nominal GPS accuracy to about 10 cm in case of the best implementations.
DGPS refers to using a combination of receivers and satellites for reducing/eliminating the common receiver based and satellite based errors reduce orbit errors reduce ionospheric and tropospheric errors reduce effects of SA eliminate satellite and receiver clock errors improve accuracy significantly 100’s of metres to metres to centimetres to millimetres.”
