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 designed by NTLab. Signals acquired by Array Antenna are digitized and processed with NTL-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.
