Description

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)1 in the L1, L2, L5, E1BC, E5a, E5b, B1, B2 bands1 under intentional and unintentional interferences.
