What is Global Positioning System (GPS)?









On this domain we will provide more information about the importance of GPS for road safety. We will discuss the benefits, risks and provide recommendations on how to use these devices.

It is perhaps most important to start from a very brief summary about what this technology:

  • The Global Positioning System (GPS) is the only fully functional Global Navigation Satellite System (GNSS). Utilizing a constellation of at least 24 Medium Earth Orbit satellites that transmit precise microwave signals, the system enables a GPS receiver to determine its location, speed, direction, and time.
  • The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use.
  • GPS works in any weather conditions, anywhere in the world, 24 hours a day.
  • It has been described as “The Most Precise Navigation System Ever Invented”
  • GPS is now a publicly available service which can be used by anyone.
