TUALCOM CRPA Anti-Jam GNSS Systems support critical missions by providing jam free GNSS signals and resilient PNT.

With its 4-element CRPA Antenna, state-of-art digital controller and novel beamforming techniques TUALAJ 4500-D eliminates interference to ensure uninterrupted operation of GNSS Receivers in the presence of up to 3 jamming sources in 5 different frequency bands. The set of protected active bands is pre-selectable amongst available options.

TUALAJ 4500-D supports various messaging formats and integrates seamlessly with civil and military GNSS receivers deployed on land/sea platforms and fixed installations. TUALAJ 4500-D also offers embedded high performance GNSS receiver as an option and allows SBAS signals to be utilized for increased accuracy and reliability.

TUALAJ 4500-D is encapsulated in specifically designed housing to withstand the harshest environmental conditions and therefore is especially suitable for maritime platforms. In addition to CRPA, protection performance is further improved using adaptive notch filtering and pulse blanking.
