Differential GPS or DGPS

DGPS uses a ground station to correct the code received from the satellites for 5 meter accuracy. DGPS could be used for Precision approaches to any airport.

to determine their latitude, longitude, and altitude. The accuracy of the system can be further refined by using a ground receiver at a known location to calculate the error in the satellite range data. This is known as differential GPS (DGPS).
