[tel-01513077] Modèles Électromagnétiques pour les Systèmes et les Canaux de Transmission de l’Aéronautique

Publications ENAC - Jeudi, 27 avril 2017 - 00:40:17
es travaux de recherche visent au développement de modèles électromagnétiques pour les systèmes et les canaux de transmission de l'aéronautique. Une des originalités est l'utilisation d'ondes élémentaires pour lesquelles existent des formulations analytiques et des décompositions. Les modèles développés reposent également sur des approximations physiques pertinentes et ils tiennent compte des spécificités de domaines d'applications souvent en lien avec l'aéronautique. Cette présentation fera une synthèse de ces activités en partant des modèles les plus généraux pour arriver à ceux tenant compte de la configuration et du système étudié. Cette démarche permettra également...

[hal-01511343] Human Factors and Neurophysiological Metrics in Air Traffic Control: a Critical Review

Publications ENAC - Jeudi, 27 avril 2017 - 00:39:13
This article provides the reader a focused and organised review of the research progresses on neurophysiological indicators, also called “neurometrics”, to show how neurometrics could effectively address some of the most important Human Factors (HFs) needs in the Air Traffic Management (ATM) field. The state of the art on the most involved HFs and related cognitive processes (e.g. mental workload, cognitive training) is presented together with examples of possible applications in the current and future ATM scenarios, in order to better understand and highlight the available opportunities of such neuroscientific applications. Furthermore, the paper will discuss the...

[hal-01225197] Air Traffic Complexity Map based on Non Linear Dynamical System

Publications ENAC - Mercredi, 26 avril 2017 - 03:03:17
This paper presents a new air traffic complexity metric based on non-linear dynamical systems. Previous work has shown that the structure and organization of traffic are important factors in the perception of the complexity of an air traffic situation. The new metric captures these important aspects of complexity by identifying the organization of trajectories in a traffic pattern. This paper investigates only the features of this new metric without quantifying directly the connection between complexity and the metric. Authors of previous work in this area have proposed metrics that generally have not explicitly addressed the effects of organization in the traffic flow...

[hal-01503222] Optimizing the Design of a Route in Terminal Maneuvering Area Using Branch and Bound

Publications ENAC - Mardi, 25 avril 2017 - 22:28:30
The sharp increase in air traffic flow causes traffic congestion in airspaces near airports, called Terminal Maneuvering Areas (TMA). The departure and arrival traffic of airports follow predesigned routes named standard instrument departure (SID) routes and standard terminal arrival routes (STAR). Optimizing these routes is crucial to regulate air traffic. Currently, SIDs and STARs are designed manually, based on the airport layout and nearby constraints. The objective of this research is to propose a methodology for designing an arrival/departure route in TMA, taking into account some constraints including obstacle avoidance. The shape of a route in horizontal plan is...

[hal-01004143] Air traffic complexity map based on non linear dynamical systems

Publications ENAC - Mardi, 25 avril 2017 - 22:26:50
This paper presents a new air traffic complexity metric based on non-linear dynamical systems. The goal of this metric is to identify any trajectory organisation in the traffic pattern in order to quantify the associated control difficulty. Many others works have proposed metrics in the past, but they usually identify one feature of the complexity and were not able to address any pattern organization. A full vector field can be summarized by the equation of a dynamical system which describe and control the evolution of a given state vector (~X = [x; y; z]T ). The key idea of our work is to find a dynamical system which modelizes a vector field as close as possible to the...

[hal-01511758] Optimal conflict resolution using B-splines and Semi-Infinite Programming

Publications ENAC - Mardi, 25 avril 2017 - 19:16:14
Our methodology aims to generate optimal conflict-free trajectories for an en-route conflict situation. Our optimization method pilots the B-splines through their control points. Consequently, trajectories are directly monitored by the semi-infinite programming method which handles both deconfliction and optimization.

[hal-01511749] Harmonic and Biharmonic Navigation Functions for Conflict-free Trajectory Planning

Publications ENAC - Lundi, 24 avril 2017 - 17:46:30
Compute a trajectory for one aircraft with theoretical proof of static obstacle avoidance.

[hal-01511688] TAROT: a network for space surveillance and tracking operations

Publications ENAC - Lundi, 24 avril 2017 - 17:46:08
TAROT: a network for space surveillance and tracking operations The TAROT (Télescope à Action Rapide pour les Objets Transitoires – Rapid Action Telescope for Transient Objects) network of telescopes consists of two 25cm aperture telescopes located at the Calern Observatory (TCA, OCA, France), the La Silla Observatory (TCH, ESO, Chile), and a 18cm telescope at Les Makes Observatory, (TRE, France). In addition we use the Zadko 1m telescope at the Gingin Observatory (ZDK, UWA, Australia). A central service in France, called CADOR (Centre d’Analyse des Données des Observatoires Robotiques, Centre for the Data Analysis of Robotic Observatories), acts as an interface for...

[hal-01511769] Formalisation des raisonnements des contrôleurs aériens dans la résolution de conflits

Publications ENAC - Lundi, 24 avril 2017 - 12:56:51
Le contrôle du trafic aérien d’un pays gère tous les avions qui volent dans son espace aérien. Il décide de la géométrie des secteurs de contrôle, gère les flux entre les aéroports et les balises, assure la sécurité´ en maintenant la séparation entre les avions, du décollage jusqu’a` l’atterrissage. Il intervient donc a` plusieurs niveaux différents. La continuelle augmentation du trafic aérien constatée et prévue rend indispensable l’étude d’amélioration, de modernisation et de redéfinition du système de contrôle actuel. Dans le cadre de l’automatisation partielle, ou` l’on prévoit de maintenir l’opérateur humain, nous proposons un système de maintien de séparation...
