4 Element CRPA Antenna Array
Compact 4-array CRPA antenna GPS/GNSS anti-jamming system
TUALCOM Anti-Jam GNSS CRPA System supports critical missions by providing jam free GNSS signals.
The system eliminates interference by applying novel beamforming techniques. With a 4-array CRPA antenna, the system can assure the normal operation of GNSS receiver in presence of multiple jamming sources.
TUALCOM Anti-Jam GNSS CRPA System 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. The product has an embedded GNSS receiver. Wide bandwidth of the system also enables the SBAS signals to GNSS receiver.
TUALAJ 4200-mini has separate anti jamming channels which support GPS L1 L2 or GPS L1 Glonass L1 bands simultaneously. Wide bandwidth of each channel also enables the M-Code and SBAS signals to GNSS receiver.
The system can be provided with various types of antennas. Physical solutions for further suppression performance such as elevation masking can also be provided as antenna option.
Supporting simultaneous GPS L1, GALILEO E1, BEIDOU B1C, SBAS, and either GPS L2 or GLONASS G1, the system can perform 40 dB wideband jamming suppression.
The unit can be provided with a variety of antennas and can be easily installed into a variety of fixed-wing and rotary UAVs as well as UGVs and USVs
