TUALAJ 4500-D

The TUALAJ 4500-D from TUALCOM is a Multi-band CRPA GNSS Anti-Jam System. This system utilizes a 4-element CRPA antenna, a state-of-the-art digital controller, and novel beamforming techniques to eliminate interference and ensure uninterrupted operation of GNSS receivers in the presence of up to 3 jamming sources in 5 different frequency bands. It supports customizable active band selection and is suitable for critical missions by providing jam-free GNSS signals and resilient PNT. In addition to CRPA, protection performance is further improved using adaptive notch filtering and pulse blanking techniques and this system is also compatible with all types of external GPS receivers and vehicle navigation systems.

The TUALAJ 4500-D supports various messaging formats and integrates seamlessly with civil and military GNSS receivers deployed on land/sea platforms and fixed installations. It also offers an optional embedded high-performance GNSS receiver and allows SBAS signals to be utilized for increased accuracy and reliability. This active anti-jam system is encapsulated in specifically designed housing to withstand the harshest environmental conditions and therefore is especially suitable for maritime platforms.
