The TUALAJ 8300-D CRPA GNSS anti-jamming system from TUALCOM provides jam-free GNSS performance and resilient PNT for critical operations in harsh environments. Equipped with an 8-element CRPA, an advanced digital controller, and adaptive beamforming algorithms, it eliminates interference from up to seven jamming sources across three frequency bands. The protected active bands are pre-selectable from available configurations to meet mission-specific requirements.
Designed for military and maritime use, the TUALAJ 8300-D integrates seamlessly with civil and defense GNSS receivers installed on land, sea, and fixed platforms. It features optional embedded GNSS capability with SBAS support for improved positioning accuracy and reliability. Encased in ruggedized housing built for severe environmental conditions, the system enhances protection through adaptive notch filtering and pulse blanking. Compliant with MIL-STD-810G and MIL-STD-461F standards, it ensures assured navigation for naval, armored, and communications applications.
