GPS (Global Positioning System)
Global Positioning System is a satellite based navigation system which consists of twenty four satellites. Twice a day they orbit the earth and as they are orbiting, they can locate where each GPS device is being used. This means that the satellites can actually find the location of the device anywhere in the world. This allows people to find other people as well as other objects.
GPS was first created by the United States Department of Defense back in the 1980′s. Originally used for military operations, over time, the Defense Department realized this Global Positioning System was much more valuable and could do much more than they first believed. Soon it was allowed to be used by civilians plus people could use it without paying for a subscription fee.
