GPS Tracking

Global Positioning Systems or GPS are satellite navigational systems made-up of 24 satellites revolving round the earth. Each satellite has a corresponding receiver on the earth. The satellites orbit the earth at a height of about 12,000 miles. It makes two complete orbits everyday. The GPS satellites continuously transmit digital radio signals that contain data on the location of the satellites and the time taken for signal transmission.
