What is GPS?
GPS or Global Positioning System is a satellite location system to determine the current
position on earth. It is a military system developed by the US Department of Defense
with approximately 30 GPS satellites circumnavigating the earth at an altitude of about
20,000 km, When signals from three or more satellites in space are received, the
current position information (longitude, latitude, altitude etc.) may be determined within
an accuracy of several meters. The accurate time can also be received from the atomic
clock built into the GPS satellite.
