GNSS anti-jam/anti-spoof for autonomous mobility
Protecting autonomous mobility applications with GNSS anti-jam/anti-spoof technology.
Protection from radio frequency interference
Anti-jamming and anti-spoofing through Hexagon's GNSS Resilience and Integrity Technology (GRIT) firmware suite.
Intentional and unintentional interference disrupts GNSS positioning within an autonomous system.
When that disruption results in being completely jammed or using spoofed/falsified measurements, your operational safety and reliability are threatened.
Overview
What causes jamming or spoofing?
Jamming describes when radio frequency interference completely overpowers your GNSS system. Spoofing is when jamming is done intentionally and falsified GNSS/GPS measurements are provided to your system, putting overall safety at risk.
The best way to ensure your autonomous application is protected from jamming and spoofing is through building resiliency and redundancy against interference.
Resilience against interference requires GRIT
GNSS Resilience and Integrity Technology (GRIT) is a firmware suite that installs into your existing Hexagon GNSS hardware and builds protection against unintentional and intentional interference.
There are other methods to protect your GNSS systems from interference, including using anti-jam/anti-jam hardware or building system redundancy with global correction services.

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.
