Description
Today anti-jamming solutions become critical for the various applications. Unmanned vehicles, automated robotic platforms, time synchronization systems, various special and military vehicles have been endangered the impossibility of receiving GNSS signals. Rapid development of jammers along with industrial noise forced to make increased demands for the interference immunity for reliable functioning. It concerns both, the design of the new products and the modernization of existing by replacing antenna to anti-jam CRPA.
Interference mitigation is achieved by applying digital null-steering algorithms to the signals, creating dynamic nulls in the antenna gain pattern to the direction of jammers. The system provides significant jamming protection even in dynamic multi-jammer scenarios both under narrowband and broadband interferences. Anti-jamming GNSS receivers are designated for the navigation data (positioning, velocity, time) determination using GNSS signals (GPS, GLONASS, Galileo, BeiDou)* in the L1, L2, L5, E1, E5a, E5b, B1, B2 bands* under intentional and unintentional interferences.
