Satellite-Based Navigation refers to the use of satellites to determine the precise location of a receiver on Earth. This technology is widely used in various applications, including GPS for personal navigation, aviation for flight tracking, and maritime navigation for ships. By receiving signals from multiple satellites, devices can calculate their exact position, speed, and direction. The most well-known system is the Global Positioning System, which consists of a network of satellites orbiting the Earth. These satellites transmit signals that are picked up by receivers, allowing users to navigate accurately in real-time, making it an essential tool for travelers and professionals alike.
