The TUALAJ 4300 GPS/GNSS anti-jamming system from TUALCOM provides jam-free GNSS operation for critical missions in demanding RF environments. Using advanced beamforming techniques and a 4-array CRPA, the system eliminates interference and ensures normal GNSS receiver functionality in the presence of multiple jamming sources. It can be configured for use with civil and military GPS receivers across land, sea, and air platforms, including unmanned systems and fixed installations.
Supporting multiple frequency combinations such as GPS L1/L2/L5, GLONASS G1/G2, Galileo E1/E5a/E5b, and Beidou B1, the TUALAJ 4300 delivers up to 40 dB of wideband jamming suppression. Designed for high performance and operational flexibility, it integrates easily with new or legacy platforms and includes optional embedded GNSS receiver capability. Built to MIL-STD-810G and MIL-STD-461F standards, it ensures assured PNT for UAVs, UGVs, USVs, armored vehicles, and airborne or naval systems.
