The anti-interference system is designed to receive, amplify, down-convert, filter and perform anti-interference processing on 4 channels of Beidou BDS B1 , GPS L1 , Galileo and GLONASS L1 frequency signals.
It operates at a power supply voltage of +1 2V to +32V. It consists of four main components: antenna array, RF component, anti-interference processing component and receiver.
It is able to counter three broadband interference sources and provide high-precision positioning and precise timing under strong interference conditions.
