Single band antenna array for Anti-Jamming (small size)

  • 4 element array
  • Using for the simultaneous anti-jamming protection from multiple directions (up to 3)
  • L1 band protection combined with AJ1.1 AntiJamming GNSS receiver
  • Single enclosure system
  • Easy and rapid to integrate in the unit
  • Reduced size and weight


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 high dynamic range receiver after which the navigation signals or solution is resistant
to jammers.
The antenna is built to withstand harsh environmental conditions and vibrations, ensuring reliable performance in various scenarios.
The antenna supports complex and separate use of GNSS systems, making it versatile in different operational contexts. The antenna is designed for future upgrades, including the potential addition of coverage in S – band frequency, as per user requirements.
