Global Positioning System
A series of twenty-four geosynchronous earth-orbiting satellites. The satellites continually transmit signals that help people determine their actual, geographic (3-D) position. This satellite-based navigation technology works 24/7, in all kinds of weather, anywhere in the world, and is accurate within 30 meters.
GPS technology has been available since 1995 through the U.S. Department of Defense's Global Positioning Satellite system and is used by millions of people (including hikers, divers, and pilots, and it is now being embedded in some automobiles). Computer scientists and Internet technologists are coupling GPS technology with wireless services so no matter where you are, you can use a handheld device to locate a coffeehouse near you.
A growing number of businesses are now beginning to track their workers and vehicles using GPS technology. This monitoring system allows the employer to keep close tabs on productivity and customer service. At any given time, the employer may zero in on a driver of a particular truck and can verify their speed and positioning.
