Accurate prediction of aircraft trajectories is an important part of decision support and automated tools in air traffic management. By combining information from multiple aircraft at different locations and time instants, one can provide improved trajectory prediction accuracy. It is shown how this multi-aircraft sensor fusion problem can be formulated as a high dimensional state estimation problem. The high dimensionality of the problem and nonlinearities in aircraft dynamics and control prohibit the use of common filtering methods. A novel particle filtering algorithm is deployed to solve it in realistic scale situations. By exploiting the structure of the problem, one can address the technical challenges that arise in the process: handling efficiently the information, dealing with the estimation of a very high dimensional state and dealing with the non-linear dynamics of aircraft motion and control. Wind forecast error, a core source of trajectory prediction uncertainty is also greatly reduced, while the algorithm can handle, with slight modifications, joint state and parameter estimation problems, such as identifying airspeed and estimating position. The effectiveness of the algorithm is demonstrated on feasibility studies involving multiple aircraft (from one to several hundred).

Yannis Lymperopoulos is an Electrical and Computer Engineer. He was granted his diploma in Engineering from the University of Patras and has finished his PhD studies at the Swiss Federal Institute of Technology (ETH Zurich). During his academic years he has collaborated with groups in Cambridge, Linkoping, Honeywell and Eurocontrol working on European funded research projects focusing on new concepts in air traffic control. He continued with his military service at the Division of Surveillance and Informatics, while also a scientific advisor to the Army Rotary-Wing Full Flight Simulator committee. This last year he has been exploiting business opportunities in his home country, with his start-up “TE-L” that designs and constructs solar power stations at the most sunny (and beautiful) locations in Southern Greece.
