It Takes Grit to Protect Your Position
GNSS Resilience and Integrity Technology (GRIT) is a firmware suite developed for our OEM7 receivers 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 analogue 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.
