Inertial Labs, a VIAVI Solutions Inc. Company, has introduced the M-AJ-QUATRO anti-jamming antenna system, designed to ensure assured positioning, navigation and timing (A-PNT) in GNSS-challenged environments. The system incorporates advanced Controlled Reception Pattern Antenna (CRPA) technology and digital processing capabilities, making it suitable for applications ranging from military operations to commercial aviation.

PNT services are increasingly critical for various sectors, including transportation, telecommunications, artificial intelligence, hyperscale data centers, energy, finance and defense. As GNSS jamming and spoofing threats grow, government agencies and industry leaders are working to address these challenges. For instance, the Federal Aviation Administration and Naval Air Warfare Center Aircraft Division are expediting approval processes for CRPA technology to enhance aviation safety and counter GPS interference.

The M-AJ-QUATRO supports the L1, L2, and L5 GNSS bands and offers robust interference suppression capabilities. Its adaptive digital nulling feature automatically mitigates jamming signals with over 34dB+ suppression in the export-free version and over 45dB+ suppression in the export-controlled version. Additionally, the system can identify and locate sources of interference through its jammer direction-finding capability, improving situational awareness.

It is compatible with multiple GNSS constellations to provide comprehensive global coverage. It employs dual FPGA-based encryption and anti-spoofing technologies for secure signal processing and data integrity. Built to meet stringent military standards like MIL-STD-810G and MIL-STD-461F, the M-AJ-QUATRO is engineered to withstand extreme conditions, making it an ideal solution for defense and aerospace applications.
