GS-97TA ANTI-JAM RECEIVER
Joint Direct Attack Munitions (JDAM) receiver
Key Features
- + Affordable protection for position, velocity and time at anti-jamming proposal
- + High anti-jamming immunity
- + Simultaneous GPS-L1, GLONASS-G1 and BD2-B1
- + Compatible with legacy GPS receivers with quick unlock recapture
- + 7-element antenna units with adaptive digital nulling, provides 6 independent nulls
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.
