Satellite Navigation
Satellite navigation uses signals from satellites orbiting Earth to determine precise locations on the planet's surface. By measuring the time it takes for signals from multiple satellites to reach a receiver, the receiver calculates its position in terms of latitude, longitude, and altitude. This system is critical for various applications, including mapping, transportation, and emergency services, providing accurate location information even in remote areas. In geodesy, it aids in Earth measurements and understanding its shape, size, and gravitational field, enhancing scientific research and practical applications in surveying and environmental monitoring.

Satellite navigation is a system that uses signals from satellites to determine the precise location of a receiver on Earth. It works by triangulating the receiver's position based on signals from multiple satellites, which orbit the Earth and continuously transmit their location and time data. This technology is widely used in devices like smartphones, cars, and aircraft, allowing users to find directions, mark waypoints, or track movements. Common examples include GPS (Global Positioning System), which is the most widely known satellite navigation system, providing accurate positioning anywhere on the planet.
