Security and Hyper-accurate Positioning Monitoring with Automatic Dependent Surveillance-Broadcast (ADS-B), Phase II

Completed Technology Project

Project Introduction

Security and Hyper-accurate Positioning Monitoring with Automatic Dependent Surveillance-Broadcast (ADS-B), Phase II
Lightning Ridge Technologies, LLC, working in collaboration with The Innovation Laboratory, Inc., extend Automatic Dependent Surveillance -- Broadcast (ADS-B) into a safe, secure, authenticated system. Historically, ADS-B has been criticized for its inability to guarantee safe and secure surveillance in all operational conditions. The technology presented provides an integrity check on all ADS-B data that is independent of all primary surveillance modes and is 100% robust to all Global Positioning System (GPS) spoofing attacks. An important by-product of that integrity check provides us with the further ability to do aircraft-to-aircraft relative positioning that is more accurate and more reliable than any civilian system in existence today. The ADS-B integrity check and the aircraft-to-aircraft positioning can provide a further basis on which to enhance the safety of the National Airspace System (NAS). Our innovation extends ADS-B into a new standard for providing safe, secure, and authentic surveillance, which is required for Separation Assurance (SA) and Traffic Flow Management (TFM) in the Next Generation Air Transportation System (NextGen).
