Introduction to GPS

The video tutorial explains the Global Positioning System (GPS), a satellite-based navigation system providing location and time information globally. Initially developed by the U.S. Department of Defense for military purposes, it became available for civilian use in the 1980s. GPS operates with a network of satellites orbiting the Earth, transmitting signals to receivers that calculate precise locations. The system is free to use, with no subscription fees. Modern GPS devices are highly accurate, functioning well even in challenging environments, and are crucial for navigation and emergency services.
