GPS stands for "The Global Positioning System". It is a satellite controlled navigation system made up of a network of multiple satellites placed into orbit. Initially GPS was only for military applications but latter on the system was made available to general public as well. The Global Positioning System works un-intrupted in all weather conditions and it serves round the clock.
Working of GPS: GPS satellites are rotating the earth in a specified orbit and they transmit signal information to earth. Signals sent by GPS satellites are recieved by GPS reciever which calculate the difference of signal timing sent and recived. The precise calculation determines the distance of reciever from the satellite. The user's position is obtained by a comparison of distance measurment with few more satellite. Electronic mapping reflects the user position which is displayed at the GPS device.
