Leading edge technology

The GS-97TA ANTI-JAM RECEIVER mitigates interference by creating nulls in the antenna gain pattern in the direction of jammers, providing significant anti-jam protection even in dynamic multi-jammer scenarios. Interference mitigation is achieved by applying proprietary digital null forming algorithms to the signals, creating dynamic nulls to give protection against narrowband and broadband interference sources.

High anti-jamming immunity

The 7-element Array-ring antenna array allows gain pattern shapes to be changed in response to interference. Provides 6 independent nulls. The type of anti-jamming signal cover the entire bandwidth span of GNSS signal and include swept waveforms, pulsed waveforms, broadband noise and other multi-frequency and time-varing versions of most of the same methods.
