Global Navigation Satellite System (GNSS)

Global Navigation Satellite System (GNSS) is a technology that uses a network of satellites orbiting Earth to provide precise location information anywhere on the planet. By communicating with multiple satellites, a GNSS receiver—like those in smartphones and vehicles—calculates its exact position (latitude, longitude, and altitude) through a process called trilateration. GNSS helps with navigation, mapping, and timing for various applications, from everyday travel to global logistics and scientific research. Common examples of GNSS include GPS (U.S.), GLONASS (Russia), Galileo (EU), and BeiDou (China).
