A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time. If such a satellite 's orbit lies over the equator and the orbit is circular, it is called a geostationary satellite.A polar satellite is one which passes through poles (polar regions).Posted by Pradeep Rout (student) on 4/11/09. geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time.

The GPS and DGPS are the satellite-based navigation systems. The basic difference between GPS and DGPS lies on their accuracy, DGPS is more accurate than GPS. DGPS was intentionally designed to reduce the signal degradation. GPS provides the accuracy about 10 meters, but DGPS can provide accuracy around 1 meter, even beyond that 10 cm.
