The M-AJ-QUATRO PRIME from Inertial Labs, a subsidiary of VIAVI Solutions Inc., is a next-generation Controlled Radiation Pattern Antenna (CRPA) system engineered to provide robust GNSS signal integrity in environments where jamming, spoofing, or signal denial is prevalent.
Purpose-built for assured Positioning, Navigation, and Timing (A-PNT), it operates across all L1, L2, and L5 GNSS bands, supporting multi-constellation compatibility including GPS, GLONASS, GALILEO, BEIDOU, and QZSS. Adaptive digital nulling, secure FPGA-based processing, and precision jammer direction-finding capabilities enable exceptional interference suppression exceeding 34dB in the export-free model, with enhanced options for export-controlled variants.
The M-AJ-QUATRO PRIME delivers optimized performance for unmanned platforms, with FPGA-secured anti-spoofing encryption and multipath mitigation ensuring accuracy in GPS-denied scenarios. Built for seamless integration with Inertial Labs navigation systems and commercial GNSS receivers, its radiation pattern control dynamically enhances signal fidelity.
With MIL-STD-810G and MIL-STD-461F compliance, this ruggedized antenna system maintains reliable operation from -40°C to +80°C and altitudes beyond 18,000 feet, making it ideal for mission-critical unmanned platforms requiring uncompromising navigation continuity.
