GPS stands for global positioning system, and DGPS stands for differential global positioning system. Both GPS and DGPS are used for satellite-based navigation systems. The main difference between GPS and DGPS is the GPS has a worldwide coverage area for its equipment, while the DGPS instruments range is local. Let us discuss some more differences between GPS and DGPS with the help of the comparison given below.
GPS Vs DGPS | Difference between GPS and DGPS
