What Is GPS?

A cellular GPS phone will be able to know the physical location of any person who makes an incoming call to the cell. This is possible, wherever in the world the caller may be.The GPS actually stands for Global Positioning System. This is a system that involves radio navigation through the use of the satellites that orbit the globe. GPS first started as a system developed by the Department of Defense of the United States. They first called it the Navigation Satellite Training and Ranging or the NAVSTAR.
This venture started sometime in the 1960's but it was only formally initiated in 1978. The endeavor developed and improved. In 1995, it became operational.
GPS operates today using three main components. These are the satellites, the earth monitoring stations and the receivers. At the moment, 24 satellites are orbiting the earth. They reach thousands of miles of distance from the surface of the earth to be able to pick signals from a large geographical area.

These satellites will then send out signals back to the earth. These signals can be received by a cellular phone with a GPS system. These signals will be processed to provide a report on a particular location. The more signals that a unit will receive from the satellites, the more accurate the report will be with regard to the position.
