A collisi on avoidance concept for VDL mode 2
2007 IEEE/AIAA 26th Digital Avionics Systems Conference, 2007The FAA is currently investigating the migration path to data-enabled digital air traffic services using VDL mode 2. Under certain loading conditions, simulations have shown that VDL mode 2 cannot meet future delay requirements with more than a few dozen aircraft per channel.

An Improved Long Transmission Protocol for VDL Mode 4
2006 International Conference on Wireless Communications, Networking and Mobile Computing, 2006An improved long transmission protocol for very high frequency (VHF) digital link (VDL) mode 4 in aeronautical telecommunications network (ATN) is proposed, which includes a combined transmission scheme and a retransmission mechanism. In the combined transmission scheme, control messages can be piggybacked in conflict-free message transmission, and ...

Some VDL applications for helicopter safety and efficient operation
Proceedings. The 21st Digital Avionics Systems Conference, 2003A new air-to-air surveillance system that consists of Global Positioning System (GPS) based position sensor, VHF data link (VDL) and cockpit display for traffic information (CDTI) had been developed. The result of the flight test showed great improvement on situational awareness of a surrounding traffic, i.e. "see and avoid" capability.

Commande en langage naturel d'agents VDL
2005L'objectif de cet article est de présenter une architecture de traitement automatique des langues (TAL) pour la plate-forme d'agents VDL développée au LIP6. Le système de TAL est composé d'un lemmatiseur-étiqueteur, d'un analyseur syntaxique et d'un analyseur sémantique. L'analyse sémantique s'appuie sur une ontologie de tâche définie pour chaque agent

Performance evaluation of two VDL Mode 3 system configurations
Proceedings. The 21st Digital Avionics Systems Conference, 2003To control a larger number of aircraft in an en route sector or on an airport surface, a new system configuration referred to as 1 Voice 3 Data (1V3D) has been added to the Very High Frequency (VHF) Digital Link (VDL) Mode 3 subnetwork. This new system configuration supports addressed voice and data communications for up to 240 aircraft in one user ...
