Global Positioning System (GPS) is a space based radio-navigation system owned by the United States government, and operated by the United States Air Force.
It is a global navigation satellite system that provides geo-location and time information to a GPS receiver on or near the earth where there is unobstructed line of sight to four or more GPS satellites. The American system has now been joined by GPS systems from Russia, the European Union, China, India and Japan.
The primary use is for navigation, allowing users to track their position on the earth's surface through sets of satellite measurements collected at different times.
GPS receivers include a display for providing location and speed information to the user. GPS has become a widely deployed tool for commerce, science, tracking and surveillance.
GPS is widely used in agriculture for sensing, monitoring and control systems used in planting and harvesting, and management of animals. GPS is used in automated vehicles applying location and route information for cars and trucks.
Mobile phones use GPS to manage the hand off from base station to base station as users move around. GPS is used in mining for drilling, vehicle tracking and surveying. GPS is also used in sport, utilities, tectonics and tourism.
GPS (global positioning system) plays a very important role in all of our lives. From allowing you to see where you are on the planet, to helping you get to destinations quickly, GPS has evolved the way in which we live our lives.
