The purpose of using the KV-4AJ4.x-RO-A GNSS jamming suppressor is to ensure stable reception of the navigation signal in conditions of staged interference. The jamming suppressor should be used with the KV-AJAx phased antenna array (see the antenna array description page). The rugged A-type enclosure is designed to work at the harsh environment and to meet requirements MIL-STD 810G and MIL-STD 461G.

Coupled with the use of a multi-band 4-element antenna array (the antenna can be provided by Kosminis Vytis), the quad-band solution allows to suppress interferences in up to 3 directions on 4 frequency plans simultaneously. This approach provides significantly higher protection against interference compared to single-frequency options.

The RF up-converter outputs the jamming-free cleared RF signal to external non-protected GNSS receiver to obtain Position, Velocity and Time (PVT).
