The TUALAJ 4500-D GPS/GNSS anti-jamming system from TUALCOM provides jam-free GNSS signals and resilient PNT for mission-critical applications. Equipped with a 4-element CRPA, a high-performance digital controller, and advanced beamforming techniques, it eliminates interference and maintains uninterrupted GNSS receiver operation in the presence of up to three jamming sources across five frequency bands. The protected active bands can be pre-selected from available configuration options.
Designed for deployment on naval, land, and fixed installations, the TUALAJ 4500-D supports multiple messaging formats and integrates easily with both civil and military GNSS receivers. An embedded high-performance GNSS receiver is available as an option, supporting SBAS signals for enhanced precision and reliability. The system is enclosed in a rugged housing optimized for harsh environments, particularly maritime platforms, and incorporates adaptive notch filtering and pulse blanking for additional protection against interference.
