DOT Report on Backup PNT Technologies Finds NextNav Performs Best, Calls for Synthesis and Synergy

The Department of Transportation (DOT) submitted its “National Timing Resilience and Security Act: Roadmap to Implementation” report to Congress in mid-January. Following a competitive application process, demonstrations and review of 11 candidate technologies to back up GPS capabilities, the DOT concluded that “none of the systems can universally backup the positioning and navigations capabilities provided byGPS and its augmentations.” However, “all vendors demonstrated some PNT performance of value, but only one vendor, NextNav, demonstrated in all applicable use case scenarios.”

CRPAs Protect Critical Infrastructure: How to Test

Since 2015, controlled reception pattern antennas (CRPAs) have come onto the market for civil applications where the need to counter increasing GNSS signal jamming and spoofing has grown exponentially. Highly classified and previously available only to authorized military users, these powerful — and unfamiliar — components expand protection for critical infrastructure. All systems incorporating them should be tested for revamped vulnerabilities. This is how.

A free webinar on Wednesday, March 25 from 1:00 PM – 2:30 PM Eastern Daylight Savings Time addresses the topic “GNSS Vulnerability Testing and the Controlled Reception Pattern Antenna (CRPA).”
