The Global Navigation Satellite System (GNSS)

The Global Navigation Satellite System (GNSS) is a network of satellites orbiting Earth that provide precise location and timing information worldwide. Devices like GPS receivers communicate with these satellites to determine their exact position, speed, and direction. GNSS is used in navigation, mapping, agriculture, and emergency services, enabling accurate positioning regardless of where you are. It relies on multiple satellites transmitting signals, which receivers interpret to calculate location through complex algorithms. Overall, GNSS is a critical infrastructure that supports numerous everyday applications by offering reliable, real-time geographic positioning globally.
