Technical Abstract

This proposal supports F20 A3.01 - Advanced Air Traffic Management Systems Concepts; Technology Area TA15 : Aeronautics - specifically, independent verification and validation of Aircraft ADS-B transmissions.

Safely achieving full autonomy and higher density in the NAS requires that the position of every aircraft in a given airspace be known to all participants in that airspace with a very high level of integrity.  GNSS  (including GPS) and ADS-B can provide sufficient aircraft-to-aircraft accuracy, but the inherent vulnerabilities of GNSS and ADS-B  to interference, jamming and spoofing require  that GNSS and ADS-B systems be independently validated for accuracy.  The ATCRBS (Air Traffic Control Radar Beacon System), based on ground-based radar interrogation of transponders, provides redundant position information in many situations.  Where position information from both ADS-B and ATCRBS exists, it can be compared for purposes of verification and validation.)  Valid position information needs to be available real time for an autonomous system to provide safe navigation, particularly for collision avoidance.  .  This proposal will develop a flexible, multi-lateration system that easily integrates the ATCRBS capability of position information into modern avionics designed for ADS-B as well as transponders.  This allows redundant independent verification of the location all equipped aircraft in all airspace.   The proposed approach can effectively provide high integrity aircraft location information that can be used for navigation and T-CAS safety functions based on aircraft-to-aircraft ADS-B data, significantly reducing usage of the transponder spectrum.


Potential NASA Applications

Independent Validation of GPS and ADS-B will enable trusted use of  ADS-B and allow much higher density use of all airspace for UAS and  air transport vehicles.  The same techniques can be applied to ground based and space based vehicles for other applications. 

Potential Non-NASA Applications

Virtually all air vehicles worldwide can make use of this approach to validation of an aircraft position.  It is a needed capability for the military and DHS  for validation that vehicles in the airspace are where they say they are.  Important for police and all emergency vehicles in the airspace as well.
