KV-AJA3-OEM
Tri-band antenna array

Category:
  • Three band multi constellation anti-jamming phase antenna array
  • 4-element for each band
  • 4 receive channels for each frequency band
  • Three band protection combined with Anti-Jamming GNSS Receiver (KV-AJ3-OEM)
  • Easy to integrate, ideal for retrofitting

 

This is 4-elements Phased Array Antenna with frequency filtering at the antenna inputs and LNA on-board. The Anti-Jamming function is achieved by using it together with Anti-Jamming GNSS receiver which includes an Anti-Jamming GNSS processor. Signals acquired by Array Antenna are digitized and processed with KV-AJ3 high dynamic range receiver after which the navigation solution is resistant to jammers.

A 4-element antenna array with Anti-Jamming GNSS receiver allow gain pattern shapes to be changed in response to interference. Provides up to 3 independent nulls.
