GPS, or Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on Earth. Developed by the United States Department of Defense, GPS consists of a network of satellites orbiting the planet. These satellites transmit signals that are received by GPS receivers, such as those found in smartphones, vehicles, and specialized devices.
GPS technology enables accurate positioning and navigation by calculating the receiver's distance from multiple satellites. By triangulating signals from at least four satellites, a GPS receiver can determine its precise latitude, longitude, altitude, and velocity. GPS is widely used for navigation, mapping, surveying, geolocation services, emergency response, and in various industries, including aviation, agriculture, logistics, and outdoor recreation.
