The Global Positioning System, or GPS, is a satellite-based navigation system that allows users to determine their exact location anywhere on Earth. It operates through a network of satellites that transmit signals to GPS receivers, which then calculate the user's position based on the time it takes for the signals to arrive. Originally developed for military purposes, GPS has become an essential tool for various applications, including driving, aviation, and outdoor activities. Its accuracy and reliability have transformed how we navigate and interact with our environment, making it a vital technology in today's world.
