Navigation and positioning are important but cumbersome activities, which GPS makes it easier.
GPS or Global Positioning Systems are computer systems that use satellites in orbit around the globe to provide exact longitudinal and latitudinal position of the user.
The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of about 18-24 satellites placed into orbit.
Navigation and maps are vital to these activities.
GPS satellites circle the earth twice a day in the same orbit and transmit signal information to down to mother earth.
For most of us, GPS has revolutionized the navigation world in a way that few could have predicted.
These satellites send radio signals from space which are received by the GPS receiver.
Along with knowing the distance, you also need to know exactly the position of the satellites in space.
