The anti-jamming system is designed to receive, amplify, down-convert, filter, and perform anti-jamming processing for 8 channels of BDS_B1 and GPS_L1 frequency signals. It operates on a power supply voltage of +12V to +32V. It is composed of composed of four main components: antenna array, RF component, anti-jamming processing component, and receiver. It can counteract three broadband jamming sources, providing high-precision positioning and accurate timing even under strong interference conditions.
