Global Positioning System is method of identifying location or position of any point or a person on earth using a system of 24 satellites, which are continuously orbiting, observing, monitoring and mapping the earth.
Working Principle:
Working Principle:
- The unique location of GPS user is determined by measuring its distance from at least three GPS satellites.
- Using these values of distances, obtained from three satellites, a microprocessor, fitted in GPS device, determines the exact location.
