Inertial Labs, a VIAVI Solutions Company, Unveils Next-Generation Anti-Jamming CRPA System for Assured Navigation
Inertial Labs, a Viavi Solutions Inc. company, has launched its M-AJ-QUATRO anti-jamming antenna system. Equipped with advanced Controlled Reception Pattern Antenna (CRPA) and digital processing technologies, M-AJ-QUATRO establishes Assured Positioning, Navigation and Timing (A-PNT) in GPS/GNSS-challenged environments ranging from military operations to commercial aviation.
PNT services are becoming indispensable for the safe functioning of a wide variety of essential services ranging from transportation, artificial intelligence (AI) hyperscale data centres, and telecommunications to energy, finance and defence. Government agencies and industry leaders are intensifying efforts to combat GNSS jamming and spoofing threats. The U.S. Federal Aviation Administration (FAA) and Naval Air Warfare Centre Aircraft Division (NAWCAD) are accelerating the approval process for CRPA technology to enhance aviation safety and mitigate terrestrial-based GPS interference.
The M-AJ-QUATRO operates across the entire L1, L2 and L5 GNSS bands, delivering interference mitigation and secure signal processing. Featuring adaptive digital nulling, it automatically suppresses jamming signals with over 34dB+ interference suppression (export-free version) and over 45dB+ interference suppression (export-controlled version), ensuring reliable performance in contested environments. The system’s jammer direction-finding capability identifies and isolates interference sources, enhancing situational awareness and operational effectiveness.
