Advanced Anti-Jamming GNSS Systems
Control the RF environment. Maintain positioning.
GNSS signals are increasingly vulnerable to jamming, spoofing, and unintentional interference. In mission-critical operations, even a brief disruption can compromise navigation, coordination, and operational effectiveness.
Maxtena's anti-jamming solutions help protect GNSS availability and integrity by detecting interference, suppressing disruptive signals, and adapting to changing RF conditions. This supports more resilient positioning, navigation, and timing (PNT) in mission-critical environments.
From Vulnerability to Control
Core Technologies
Controlled Radiation Pattern Antenna (CRPA)
Precisely controls antenna reception patterns to reject interference while preserving desired satellite signals.
Adaptive Nulling Algorithms
Continuously mitigate multiple jamming sources by dynamically adjusting the antenna pattern in real time.
Digital Beamforming
Enhances signal directionality and clarity, improving performance in complex RF environments.
INS Integration
Maintains positioning continuity when satellite signals are degraded or temporarily unavailable.
Secure FPGA Processing
Provides secure FPGA-based processing engineered for resilient anti-jamming performance.
Integrated System Architecture
Combines antenna hardware, signal processing, and streamlined interfaces in one compact, deployable system, reducing integration complexity and potential failure points.
Built for Demanding Operational Environments
What Sets Maxtena Quatro Prime Apart
Adaptive Real-Time Interference Suppression
Quatro Prime continuously detects and suppresses interference to protect positioning accuracy and maintain reliable GNSS performance in contested environments.
Integrated Design - No External Controller Required
All critical components are integrated into a single compact system, simplifying installation, reducing external hardware requirements, and minimizing potential failure points.
High Performance in a Compact Four-Element Architecture
Advanced CRPA technology in a compact four-element architecture delivers exceptional performance while minimizing size, weight, and power requirements.
Traditional Systems Fall Short. Maxtena Outperforms
Traditional systems are often bulky, heavy, power-hungry, and complex, which can limit performance and increase operational risk. Quatro Prime delivers a more compact, efficient, and resilient alternative.
Rapid Integration Across Defense and Autonomous Platforms
Quatro Prime is designed for seamless integration across a wide range of modern mission platforms, enabling faster deployment and reliable performance in demanding environments.
