The Global Positioning System or GPS have been discovered by the U.S. Department of Defense (D.O.D) and Ivan Getting. GPS is a satellite-based navigation system that is made up of 24 satellites. It was originally made for military applications, however in the 1980s, the Government made it available even for civilian use. GPS provides its services in any weather conditions, 24 hours a day and from anywhere in the world. The technology makes use of a satellite to track your whereabouts on the earth. You do not have to pay any setup charges or subscription fees to use GPS.
GPS technology can be divided into two groups. They are:
- Tracking device
- Navigation system
GPS tracking device – The GPS tracking device is the simplest type of technology. You can use them in combination with the communication technologies such as telephony and radio transmission. With the help of tracking device, a tracking center can watch the movements of various vehicles or people. These may be military-men, police, criminals or young children whose parents want to watch them when they’re away. The tracking device has GPS software, GPS receiver and a device to broadcast the resulting co-ordinates like cell phones or GPS watches that send out radio waves.
GPS navigation system – When any user is located through GPS, the location can be recognized on a map. This is helpful for the tasks such as looking for a route, locating a unit or choosing a suitable route. However, navigation requires map work and this is not at all a part of the GPS system. As such, mapping needs to be done by using associated technologies which often requires the usage of movable computers and gadgets.
