GNSS anti-jam, anti-spoof for defence
GNSS anti-jam/anti-spoof technology to protect against interference, jamming and spoofing.
What is anti-jamming?
GPS/GNSS signals are susceptible to interference and jamming. Learn why and how you can protect your signals.
The GPS Anti-jam Technology (GAJT) portfolio of anti-jam solutions
Protect your positioning, navigation and timing from interference, jamming and spoofing attempts.
Anti-jam for offshore and in the littoral
If their positioning system is jammed, vessels have no geographic landmarks to navigate by, threatening operations.
What it means for your GNSS position to be jammed or spoofed
Our 'Introduction to GNSS' series explains interference, jamming and spoofing, including what it means to be GNSS-denied.
Interference, both intentional and benign, is increasing worldwide due to a crowded radio frequency spectrum and the availability of low-cost GPS jamming devices. You need a layer of protection to ensure your positioning, navigation and timing (PNT) remains reliable, available and accurate.

Anti-jam for vehicles and fixed installations
Interference, jamming and spoofing can occur anywhere and anytime. Land vehicles and fixed installations rely on assured positioning, navigation and timing information. Your operations, people and assets come under threat if this information is no longer reliable or accurate.
GPS Anti-jam Technology (GAJT) provides a layer of protection and resiliency against the growing threat of interference, jamming and spoofing to military vehicles and platforms, networks and timing infrastructure. With jammer direction-finding capabilities, GAJT provides situational awareness for users to better characterise their RF environment. A silent mode feature reduces its thermal signature to aid in avoiding detection.
With simple integration into new and legacy GNSS receivers, as well as compatibility with M-code, GAJT identifies, mitigates and protects against jamming and spoofing attempts.
Jamming and spoofing protection at sea
When there are no geographic landmarks to navigate by, GNSS/GPS positioning solutions become even more vital. Whether offshore or in the littoral, marine vessels rely upon their positioning, navigation and timing measurements to ensure continuous and safe operations for crew, vessels and cargo.
The 2017 spoofing event in the Black Sea revealed how vulnerable marine vessels are to radio frequency interference and jamming. Whether in defence, commercial shipping, nearshore piloting, hydrographic or seismic survey, or offshore energy and construction, vessels require assured positioning, navigation and timing.
GPS Anti-jam Technology (GAJT) delivers protection against unintentional and intentional interference, including jamming and spoofing attacks, ensuring an assured positioning solution anywhere at sea.
Unmanned and autonomous platforms
Anti-jam capabilities are vital for unmanned and autonomous platforms, as interference can overpower positioning systems to the point of total GNSS denial. This situation leaves the platform vulnerable.
Further, unmanned and autonomous platforms, including aerial vehicles or marine vessels, require low size, weight and power (SWaP) jamming protection.
The GPS Anti-jam Technology (GAJT) portfolio includes low-SWaP options for land platforms, marine vessels and aerial vehicles, providing assured positioning, navigation and timing for mission-critical operations.

We’re climbing the automation curve
Our transition to Intelligent automation is accelerating. Ultimately, our innovations will give rise to new technologies and applications - many of which we’ve yet to imagine. Today, every Hexagon solution is mapped and tagged according to its level of automation, so customers can clearly track our progress towards the freedom of autonomy.
Human-driven
All tasks completed by human labour; no data is leveraged across the operation.
Human-assisted
Labour is primarily conducted by a human workforce. Some functions have been automated to simplify control.
Partial automation
Some tasks are automated for short periods of time, accompanied by occasional human intervention.
Conditional automation
Human workforce is used for intervention as autonomous operations begin to increase productivity.
Highly autonomous
Autonomous systems complete required tasks within specific bounds, unleashing data and building smart digital realities.
Full autonomy
A smart digital reality™ enables autonomous systems to complete all tasks without human intervention.
Land
Products that make an environmental impact in forest monitoring, material reusability, farming or water usage.
Air
Products that make an environmental impact in renewable energy, noise pollution elimination and e-mobility.
Water
Products that make an environmental impact in saving our oceans, reducing pollution and increasing access to clean water.
