The Global Positioning System is a system for determining the position on the earth’s surface with the help of satellite signal synchronization. This system uses 24 satellites that send microwave signals to Earth. This signal is received by the receiver on the surface, and is used to determine the location, speed, direction and time. Systems similar to GPS include Russian GLONASS, European Union Galileo, India’s IRNSS.
This system was developed by the United States Department of Defense, with the full name being NAVSTAR GPS (a common mistake is that NAVSTAR is an acronym, this is wrong, NAVSTAR is the name given to it by John Walsh, an important policymaker in the GPS program). This collection of satellites is maintained by the United States Space Force’s 50th Space Wing. Maintenance costs for this system are approximately US $ 750 million per year, including replacement of old satellites, as well as research and development.
GPS Tracker or often referred to as GPS Tracking is an AVL (Automated Vehicle Locator) technology that allows users to track the position of vehicles, fleets, or cars in Real-Time. GPS Tracking utilizes a combination of GSM and GPS technology to determine the coordinates of an object, then translate it into a digital map.
