What is GNSS?

 

GNSS (Global Navigation Satellite System) refers to satellite-based positioning systems consisting of multiple orbiting satellites. Satellites continuously transmit RF signals. Terminals equipped with GNSS antennas receive these signals and calculate precise position, velocity and time data via multi-satellite computation.

 

GNSS covers four major navigation constellations: Beidou, GPS, GLONASS and Galileo. Corresponding GNSS antennas mostly adopt right-hand circularly polarized ceramic design with high receiving sensitivity and support multi-constellation joint positioning.

 

Independent of terrestrial cellular base stations, it works even in remote field and sea areas without mobile coverage. Widely used in vehicle terminals, drones, asset trackers, construction machinery and outdoor IoT devices.
