Performance verification of VoIP for terrestrial communications and IP surveillance data for air traffic management

This paper presents test procedures and methodologies for performance verification of Voice over IP technology for ground-ground communications (Radio and Telephony) according to EUROCAE ED-136 requirements and also Surveillance Data (RADAR) according to EUROCONTROL IP-SDE Task Force requirements in an Aeronautical Telecommunications Network (ATN) based on IP Standards and Protocols according to ICAO Doc 9896 recommendations. These procedures and methodologies were performed successfully in the South Trial in Brazil and intended to analyze and validate an all-IP integrated terrestrial communications infrastructure appropriate for Air Traffic Management, taking into account the national plan for CNS/ATM development. One of the main benefits of these procedures and methodologies is that they can be easily and effectively reproduced to validate the implementation of a future IP based ATN in other regions of the Brazilian Airspace Control System (SISCEAB). Finally, this paper shows the preliminary results of these systemic tests and the conclusions.
