TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Lightning Ridge Technologies, 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 in this proposal provides an integrity check on all ADS-B data that is independent of all primary surveillance modes and is 100% robust to all 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).

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Traffic Flow Management (TFM), Separation Assurance (SA), Super Dense Operations (SDO) and Unmanned Aerial Vehicles (UAV) in the National Airspace all make heavy use of Automatic Dependent Surveillance Broadcast (ADS-B). This proposal presents technology that brings extra capability to ADS-B in the form of unspoofable authentication and a method called differential co-processing that can calculate the relative position between aircraft more accurately than any civilian method today.
The potential impact of these capabilities on NASA's NextGen requirements ranges from ADS-B authentication, detection and identification of attacks; to using better relative positions to determine more accurate wind-shear models and enabling precise trajectory modeling during Very Closely Spaced Parallel Approaches (VCSPA). In short, the GPS Based Location Authentication and Differential Co-Processing could change and accelerate the course of NextGen development.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
ADS-B is a public interface, an easy target for attack. The US Air Force is actively studying how to add security to ADS-B to ensure that attempts to disrupt military missions are identified and counter attacked. In particular the Air Force is concerned that enemies could add ghost aircraft to congested airspace for the purpose of disrupting C17, C130 and C5 flights that supply troops overseas. The GPS Location Based Authentication (GBLA) technology presented in this document can solve that concern. In addition the Differential Co-Processing techniques to calculate relative position between aircraft can act as a backup to the air-to-air radars currently deployed for operations such as formation flying.
The largest military application of GBLA may not be in aviation. GBLA provides military quality GPS authentication without needing a reference copy of the secret military GPS codes. GBLA embedded into a handheld GPS receiver allows that receiver to be built entirely with civilian hardware, drastically reducing the cost of the receivers.
