The purpose of using the KV-4AJ4.x-RO-OEM module is to ensure stable reception of the navigation signal in
conditions of staged interference. The module should be used with the KV-AJAx phased antenna array (see the
antenna array description page), and can be separately integrated into a third-party device. This OEM module can
also be presented in the form of rugged enclosure version with external connectors to meet the requirements of
IP or MIL-STD (please see the KV-4AJ4.x-RO-R and KV-4AJ.x-RO-A series).
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).
