The M-AJ-QUATRO from Inertial Labs is an Anti-Jamming Antenna Solution that can be used to protect GPS L1, L2, L5, GLONASS, GALILEO, BDS, and QZSS bands. It incorporates Controlled Radiation Pattern Antenna (CRPA) technology alongside state-of-the-art signal processing capabilities that ensure that the antenna's radiation pattern is precisely controlled, optimizing both signal reception and transmission. This allows the system to focus on desired signals while minimizing interference from unwanted sources.
The CRPA technology also minimizes signal distortions, resulting in superior GNSS positioning accuracy, and also significantly improves the system's resistance to interference and jamming. By dynamically adjusting the radiation pattern, it can nullify or reduce the impact of interfering signals, maintaining high signal quality. CRPA technology mitigates multipath effects, ensuring that the strongest, most direct signal is used for positioning, thus enhancing overall signal integrity and accuracy.
The M-AJ-QUATRO is engineered for Assured Positioning, Navigation, & Timing (APNT) across diverse GNSS jammed, spoofed and denied environments and has low latency, high interference suppression, adaptive nulling & jammer direction-finding features. It has a gain of 2 dBic at over 15 degree elevation, RHCP polarization and a suppression of over 34 dB. This solution also has built-in security features that protect against signal tampering and unauthorized access. It utilizes FPGA-based secure signal processing to implement advanced encryption and anti-spoofing features, ensuring the integrity and security of GNSS signals.
This anti-jamming solution requires a DC supply of 12 to 28 V and consumes less than 10 W of power. It is available in a module that measures 132 x 132 x 19 mm and has MCX connectors. This solution is ideal for defense and sensitive commercial applications.
