How Does a GPS Tracker Work

GPS is an acronym for global positioning system. It is a global radio-navigation system. It functions using data transmitted from about 24 satellites. These satellite systems are referred to as Global Navigation Satellite System (GNSS).

Prior to answering the question: how does a GPS tracker work, lets look at how it all started.

The GPS technology is owned by the United States Defense Department.

Back then, it was designed for use by the US military for their operations. However, its use has gained widespread application in even civilian use all over the world. This civilian use is limited, though.

The civilian application and use of GPS technology is restricted and constantly reviewed by the Department of Defense (DOD).

This GPS technology is also used by the military of other nations on the approval of the United States DOD. Such licenses are not available for civilian use and are subject to the laws of the United States.

The GPS tracking device is used as a location device. It is used to provide geographical location of any object on the earth surface using satellite data. It can be kept in a car, a phone or even on a person. It then provides information on the person’s exact location at any given time.

Its civilian application is broad. The use of GPS data, emanating from clock and positional synchronization, is used in the discovery of extrasolar planets. It is also extensively used in civilian and military cartography.

The application of GPS in clock synchronization also helps in cellular telephony. Automated vehicles use GPS for navigation through their designated routes.
