Safeguard your operations against GNSS jamming & spoofing attacks
The world has come to rely on GNSS... but it's vulnerable

Global Navigation Satellite Systems (GNSS) such as GPS and Galileo have become ubiquitous in modern life; most of us use it every day without a second thought and global economies depend on it.
GNSS signals though are inherently weak, and easily overpowered by strong RF signals emitted by attackers intent on causing disruption.
Such jamming attacks have the effect of degrading positional accuracy whilst more sophisticated spoofing attacks fool the receiver into believing it's somewhere that it's not.
GNSS attacks reaching epidemic proportions
GNSS signals easily jammed or spoofed
More than 800 flights being disrupted daily
All main shipping corridors now experiencing disruption

Combating GNSS interference using a CRPA anti-jamming antenna without sacrificing GNSS performance is challenging
A controlled reception pattern antenna (CRPA) is the gold standard for combatting GNSS jamming and spoofing attacks.
But developing one that is effective against inadvertent and malicious GNSS interference whilst retaining antenna performance for high positional accuracy (RTK) is far from simple, and especially so if the solution must be compact and fit within stringent size, weight and power (SWaP) constraints to support a wide range of applications.
Our CRPxTM technology delivers unrivalled GNSS protection
Helix Geospace set out to address this challenge with the CRPx GNSS Anti-Jamming System
Our CRPx is an integrated CRPA (antenna array + processing) that delivers military-grade jamming suppression, whilst maintaining GNSS signal linearity for universal GNSS receiver compatibility and high-precision positioning (RTK), and in a compact and lightweight form factor and price point that allows these advanced capabilities to be accessible to a wide range of defence and commercial applications across land, sea and air.
