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.


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.
