Overview

BTSTC-AT028 Anti-Jamming CRPA System supports critical missions by providing jam free GNSS signals.
With an 8-array CRPA antenna, the system can assure the normal operation of GNSS receiver in presence of multiple jamming sources.

It 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.

It 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.
