The purpose of using the KV-AJx RAJA GNSS receiver is to ensure stable reception of the navigation signal, including S-band signal, in conditions of staged interference. The receiver must be used with the KV-AJAx phased antenna array (see the antenna array description page). Small-size case dimensions allow to implement high-performance systems in space-effective solutions.
Coupled with the use of a multi-band 4-element antenna array (the module can be provided by Kosminis Vytis), the tri-band solution allows to suppress interferences in up to 3 directions on 3 frequency plans simultaneously. This approach provides significantly higher protection against interference compared to single-frequency options. KV-AJx RAJA receiver contains a MEMS inertial sensor and thus allows to create the GNSS-aided INS (GNSS+INS) solutions for position, velocity, time, and attitude. The jamming-free cleared RF signal can also be delivered to external non-protected GNSS receivers to obtain position, velocity, and time.
