The TUALAJ 4300 from TUALCOM is a GNSS Anti-Jam CRPA System that supports critical missions by providing jam free GNSS signals. It eliminates interference by applying novel beamforming techniques. The system has an embedded GNSS receiver (BeiDou (B1C)/Galileo (E1, E5a, E5b)/SBAS GLONASS (L1, L2)/GPS (L1, L2)/QZSS (L1)) and can have 3 simultaneous active bands. It has an internal GNSS tracking sensitivity of -164 dBm and provides a nominal wideband suppression of more than 40 dB. The system requires a DC supply voltage from 12 to 36 V and consumes less than 18 W of power.
With a 4-array Controlled Reception Pattern Antenna (CRPA) antenna, the system can assure the normal operation of GNSS receiver in presence of multiple jamming sources. It can be employed using various configurations and operates with civil and military GPS receivers for the land, sea, air platforms (including unmanned aerial systems) and fixed installations. Wide bandwidth of the system also enables the SBAS signals to GNSS receiver.
The TUALAJ 4300 is available in a module that measures 11.0 x 10.0 x 2.7 cm with 5 x SMA-female connectors and supports Ethernet and Serial data interfaces. It is suitable for use in Fixed Winged Aircraft, Rotary Wing Aircraft, Guided Munitions, Unmanned Autonomous Systems, Armored Vehicles, Naval Platforms, Coast Guard Platforms, Maritime Cybersecurity, Advanced Transportation Systems, Military Communications, Armored Trucks and Critical Asset Tracking.
