Precise Positioning for Unmanned Vehicles: GPS & GNSS Receivers, Antennas & Inertial Systems

New GNSS Anti-Jamming & Spoofing Technology Released

By Mike Ball / 10 Nov 2020

NovAtel OEM7 GNSS ReceiversHexagon | NovAtel has introduced GRIT (GNSS Resilience and Integrity Technology), the company’s new suite of firmware features that enables users to protect position, navigation and timing (PNT) measurements from interference, jamming and spoofing. The new solution provides reliability, resilience and advanced situational awareness for a wide range of applications, including UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles) and other robotic platforms.

GRIT is available as an option with NovAtel’s latest 7.08.00 firmware release, and combines NovAtel’s successful Interference Toolkit (ITK) with advanced spoofing detection. Optional GRIT capabilities include enabling time-tagged snapshots of analog to digital samples. The time-tagged digitized RF data allows users to characterize the RF environment and develop their own interference location algorithms.

Through spoofing detection, time-tagged data and interference mitigation such as anti-jam technology and digital filters, GRIT builds GNSS resiliency and integrity to better protect position, navigation and timing measurements. GRIT complements NovAtel’s GAJT anti-jam technology in providing resilient, robust and trustworthy PNT protection.

GRIT is a non-controlled firmware-only solution and can be easily installed without the need for specific export licensing. It is available as a firmware upgrade for all NovAtel OEM7 receivers and ensures trustworthy position, navigation and time measurements through proven situational awareness and interference mitigation.

Sandy Kennedy, VP of Innovation at Hexagon’s Autonomy & Positioning division, commented: “We’ve combined our world-class Interference Toolkit with new functionalities like time-tagged snapshots and spoofing detection to provide users with a comprehensive suite of mitigation tools. Expanding our protection portfolio through this firmware suite to prioritize situational awareness and mitigation for anti-jam and anti-spoofing techniques makes it easier than ever for users across any industry to achieve assured PNT. With GRIT’s spoofing detection, opponents could try to spoof us. But, fool us? Not a chance.”
