Miniaturized 7-Element Multi-System GNSS Anti-Jamming Terminal for UAVs

Miniaturized 7-Element Multi-System GNSS Anti-Jamming Terminal for UAVs

This miniaturized integrated anti-jamming unit is designed for civil UAVs and industrial applications, supporting BDS, GPS, GLONASS, and GALILEO systems. It provides anti-wideband jamming capability with resistance to up to six simultaneous interference sources. The device integrates an antenna array, anti-jamming module, and a GNSS receiver into a single compact unit, offering miniaturization, light weight, and low cost.
