This is 4-elements Phased Array Antenna with frequency filtering at the antenna inputs and LNA on-board. Antenna Array forms the core of the system, providing exceptional signal reception and transmission capabilities.

The Anti-Jamming function is achieved by using it combined with Kosminis Vytis Anti-Jamming GNSS receiver which includes an Anti-Jamming GNSS processor. Signals acquired by Array Antenna are digitized and processed with KV-AJ1.1 (KV-AJ1.1-OEM) high dynamic range receiver after which the navigation signals or solution is resistant to jammers.

The antenna is designed for future upgrades, including the potential addition of coverage in S – band frequency, as per user requirements.
