GNSS

Global Navigation Satellite System (GNSS) is a collective term for satellite-based systems that provide accurate positioning and timing data worldwide. The best-known GNSS systems include the United States’ GPS, Russia’s GLONASS, the EU’s Galileo, and China’s BeiDou.

GNSS relies on satellites orbiting the Earth that transmit radio signals to ground-based receivers. These receivers—found in smartphones, car navigation systems, and surveying equipment—use the signals to determine precise location. GNSS technology is widely used across industries such as logistics, aviation, maritime, agriculture, and scientific research. It supports activities like vehicle tracking, aircraft navigation, ocean mapping, and precision farming.

The accuracy and reliability of GNSS systems have significantly improved in recent decades, making them an integral part of modern society.
