As an official partner and distributor of Inertial Labs (VIAVI Solutions) technologies, General Guidance is pleased to announce the launch of the new M-AJ-QUATRO Anti-Jamming CRPA Antenna System — an advanced Assured Positioning, Navigation, and Timing (A-PNT) solution designed to deliver secure and reliable GNSS performance in contested and interference-prone environments.
Developed using advanced Controlled Reception Pattern Antenna (CRPA) and digital signal processing technologies, the M-AJ-QUATRO is engineered to mitigate GNSS jamming and spoofing threats across military, aerospace, and commercial applications where uninterrupted navigation performance is mission-critical.
Addressing Growing GNSS Interference Threats
As positioning, navigation, and timing (PNT) services become increasingly essential across sectors such as defense, aviation, telecommunications, energy, transportation, and critical infrastructure, protection against GNSS interference has become a strategic priority worldwide.
The launch of the M-AJ-QUATRO comes at a time when organizations such as the U.S. Federal Aviation Administration (FAA) and Naval Air Warfare Center Aircraft Division (NAWCAD) are accelerating CRPA technology adoption to improve navigation resilience and aviation safety.
Advanced Anti-Jamming and Anti-Spoofing Capabilities
The M-AJ-QUATRO operates across the full L1, L2, and L5 GNSS frequency bands, delivering advanced interference mitigation and secure signal processing capabilities.
Key system features include:
- Adaptive digital nulling technology for automatic jammer suppression
- More than 34 dB+ interference suppression in export-free configurations
- More than 45 dB+ interference suppression in export-controlled versions
- Jammer direction-finding capability for enhanced situational awareness
- Secure FPGA-based encryption and anti-spoofing protection
- Reliable operation in highly contested electromagnetic environments
The system is designed to identify, isolate, and suppress interference sources while maintaining continuous navigation performance for mission-critical operations.
Multi-Constellation Global Coverage
The M-AJ-QUATRO supports multiple global navigation satellite constellations, including:
- GPS
- GLONASS
- GALILEO
- BEIDOU
- QZSS
This multi-constellation compatibility provides enhanced positioning resilience and robust global operational coverage.
Rugged Design for Defense and Aerospace Applications
Built for harsh operational conditions, the M-AJ-QUATRO complies with stringent MIL-STD-810G and MIL-STD-461F standards, making it suitable for demanding defense, aerospace, and government applications where reliability and survivability are essential.
The solution is ideally suited for:
- Defense and tactical operations
- Military aviation platforms
- Unmanned aerial systems (UAS/UAV)
- Critical infrastructure protection
- Commercial aviation navigation resilience
- Secure autonomous platform operations
Supporting the Future of Assured Navigation
The introduction of the M-AJ-QUATRO represents another important step in the evolution of Assured PNT technologies, helping operators maintain secure and interference-resistant navigation capabilities in increasingly complex operational environments.
