Définition
GPS (Global Positioning System) is a satellite-based navigation system that allows us to pinpoint our location on Earth. It has revolutionized the way we travel, explore and do business. GPS was originally developed in the 1970s by the U.S. Department of Defense to provide navigation and timing services. Over time, GPS technology has been improved and adapted to many other uses.
Today, GPS is used in a wide variety of applications, from tracking freight shipments to finding your way around a new city.GPS is based on a network of 24 satellites orbiting the Earth. Each satellite transmits a signal that is picked up by GPS receivers. By using the signals from at least four satellites, the receiver can calculate its exact position on the Earth.GPS technology has advanced significantly over the years, and it is now used for a variety of applications.
For instance, it is used for navigation in cars, boats, and airplanes, for tracking animals, for accurately measuring distances in sports, and for finding your way around a city. GPS is also used to locate and map natural resources, and to assist police and emergency personnel in responding quickly to incidents.GPS technology has become an essential part of our lives and has changed the way we live and work. We can now explore the world with confidence, and easily make our way to our destination.
