Advanced air traffic management technologies: the ads-b impact over atm concepts. The case for portugal

摘要

In today’s CNS/ATM (Communication, Navigation, Surveillance/Air TrafficManagement) paradigm the Automatic Dependent Surveillance Broadcast (ADS-B) is avery important tool in the improvement of surveillance precision, incising the trafficefficiency with even better safety parameters and lower delays.All around the world programs and projects to implement the ADS-B technology aretaking place with trials being made with the participation of Air Navigation ServicesProviders (ANSP’s), focusing Air Traffic Controllers duties, Aircraft Operators, focusingpilots duties, and Aircraft and Avionics manufacturers, to validate the efficiency andsafety of this system, as well as the cost, time and changes to make this happen. Theoutcome of this will certainly affect the shape of ATM surveillance in the short and longterm.This work initially presents an overview of the current situation, i.e., on how surveillanceis made nowadays, then an overview of the ADS-B system and its technology, and finallya cost/benefit evaluation of the implementation of this new technology within thePortuguese FIR’s.
