Q. How does the navigation system ‘Global Positioning System (GPS)’ work?
Ans. Global Positioning System (GPS) is a universal navigation system which consists of a constellation of about 24 satellites orbiting the earth and different tracking stations that are located across the globe. The satellites transmit the microwave signals to the specialized GPS devices on the ground. The various signals from the GPS satellites are controlled and monitored by the tracking stations to provide the exact position of GPS receivers.
