The anti-jamming system is designed to receive, amplify, down-convert, filter, and perform anti-jamming processing for multi channels of BDS_B1，BDS_B2，GPS_L1 ，GPS_L2 ，GPS_L5，GLONASS_L1，GLONASS_L2，GALILEO L1，GALILEO E5A，QZSS L1，QZSS L2，QZSS L5，IRNSS L5 and IRNSS S 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.
