Innovation: Mode N provides alternative PNT for aviation
Mode N could meet the need for a reliable alternative PNT system for aircraft navigation. It builds on aspects of existing navigation systems and aviation-certified signals not originally intended for navigation, including some used for communications and surveillance. In this article, a team of researchers from the German Aerospace Center describe Mode N, looking at its signal format, required ground infrastructure, aircraft avionics and the potential position accuracy this system could offer.

Answering the Military’s Need for Assured Positioning, Navigation and Timing (A-PNT), Which is Ready Today
Date: Thursday, December 9, 2021
Time: 1pm EST
Duration: 60 minutes + extra time for Q&A
Sponsored Content by: Leondardo DRS
Summary: U.S. military positioning technology relies heavily on the Global Positioning System (GPS). Yet, in recent years jamming, spoofing, and other forms of interference have grown in frequency and severity. This creates risks for military forces when encountering technologies that degrade the GPS capability on combat vehicles. The solution to this challenge is Assured Positioning, Navigation, and Timing (A-PNT) – a way to provide accurate PNT information at all times under all conditions. Given this threat, Combatant Commanders are requesting alternate PNT systems to GPS for their maneuver formations.
In this webcast you will learn about a variety of technologies and tiered solutions that can ensure our forces are able to win in a contested GPS environment for all ground vehicle platforms that are ready today and that can be fielded quickly and affordably.
Speakers:
Dr. Kevin Betts, Position, Navigation, and Timing Director. Leidos Innovation Center
Mike Stucki, Business Development Director, Mission Systems Campaign
