4-array CRPA GPS/GNSS interference suppression system

The TUALAJ 4300 GPS/GNSS anti-jamming system is designed to maintain reliable GNSS functionality in challenging RF environments where interference is present. Utilizing a 4-array CRPA and advanced beamforming techniques, the system suppresses multiple jamming sources to ensure continuous GNSS receiver operation during mission-critical activities.

Supporting a wide range of frequency combinations, including GPS L1/L2/L5, GLONASS G1/G2, Galileo E1/E5a/E5b, and Beidou B1, the system delivers up to 40 dB of wideband jamming suppression. This multi-frequency capability enhances PNT performance across complex operational scenarios.

Designed for operational flexibility, the TUALAJ 4300 can be configured for use with both civil and military GPS receivers across land, maritime, and air-based defense platforms, as well as fixed infrastructure. It also includes an optional embedded GNSS receiver, enabling adaptable deployment depending on system requirements.

The system is engineered for straightforward integration with both new and legacy platforms, supporting deployment across a range of defense applications including armored vehicles, airborne systems, naval platforms, and wider tactical operations. Built to MIL-STD-810G and MIL-STD-461F standards, it ensures dependable performance and assured PNT in demanding operational conditions.
