Product details

GENERAL DESCRIPTION 

TX18 Anti-Jam CRPA System supports critical missions by providing jam free GNSS signals. With an 11-array CRPA antenna( 7 + 4 ), the system can assure the normal operation of GNSS  receiver in presence of multiple jamming sources. TX18 Anti-Jam CRPA System can be employed using various configuration 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 that supports  all satellite constellations. 

How it works 

TX18 mitigates interference by creating nulls in the antenna gain pattern in the direction of  jammers, providing significant anti‑jam protection even in dynamic multi‑jammer scenarios.  The output is a protected standard Radio Frequency (RF) signal, free from jamming and  suitable for input to modern and legacy GNSS receivers.
