GPS is basically a global positioning system used to locate a GPS receiver, which will receive in three-dimensional space anywhere you might be on earth. GPS is controlled by 21 active orbiting satellites at almost 12000 miles above the Earth. The GPS nav

How does a GPS unit work?

The GPS navigation unit is all based on precise time measurement. All satellites that are used for GPS positioning and tracking have several atomic clocks on boar
