The ATJ-301 anti-jamming integrated unit supports reception, down-conversion, and amplification for 7 channels of BDS_B1, GPS_L1, GALILEO_E1, and GLO_G1 signals. It can combine and forward the radio frequency signals—after interference filtering—to the receiver. The unit is equipped with adaptive anti-jamming processing capabilities and can be widely applied to mobile vehicles, aircraft, and unmanned platforms. It delivers excellent navigation anti-jamming performance.
