GNSS Resilience and Integrity Technology (GRIT) is a firmware suite developed to expand situational awareness and interference mitigation tools across applications and environments to protect against global navigation satellite system (GNSS) interference.
To protect your position, navigation and timing measurements, users must be able to identify when something is amiss in their environment. GRIT includes NovAtel’s successful Interference Toolkit (ITK) and spoofing detection to identify when your GNSS signal is under threat. Detailed situational awareness is the first step to building resiliency and integrity of a user’s position.
Once a user’s environment is characterized, GRIT enables interference mitigation through anti-jam technology and digital filters. Also included in GRIT is the optional functionality enabling time-tagged snapshots of analog to digital samples so users can characterize jamming signals and develop their own interference location algorithms. This comprehensive approach to awareness and mitigation builds GNSS resiliency and integrity.
GRIT enables spoofing detection for a comprehensive understanding of your RF environment to identify when your position, navigation and timing is at risk.
A resilient signal requires protection. ITK identifies and characterizes interference frequencies in your area, protecting you from unintentional and malicious interference.
Time-tagged snapshots of analog to digital data samples allow users to characterize the RF environment and develop their own interference location algorithms.
