Dual-frequency Four-channel Global Navigation Satellite System GNSS Anti-Jamming System Anti Jammer GPS

The anti-jam system is designed to receive, amplify, down-convert, filter, and perform anti-jam processing on BeiDou BDSB1 , GPS L1 , and GPS L2 ,GALILEO E1 frequency signals.

It operates on a supply voltage of +1 2V to +32V. It consists of four main components: antenna array, RF components, anti jammer processing components, and receiver.

It is able to counter three broadband interference sources,providing high-precision positioning and precise timing under strong interference conditions.
