Eurocontrol on Nov. 8 commemorated the ARTAS service, the ATM surveillance Tracker and Server, a concept launched 20 years ago at the request of European member states.

The ARTAS system establishes an accurate picture of all traffic over a well-defined geographical area, distributing relevant surveillance information to the user. It is currently used by 15 ECAC states at 27 civil and military Air Traffic Control Centers, while at least 13 additional States are planning to put it in operation.

"ARTAS is a good example of the importance of the Network -- a network that is becoming ever more important as traffic grows and s a single event can cause ripples of disturbance right across Europe," said David McMillan, the agency's director general. "It is an excellent example of how a united approach can bring real benefits, reducing fragmentation and improved integration."

The member states were aiming to bolster Eurocontrol's central role in technical coordination and its expertise in communication and surveillance. It now stands, according to the agency, as one of the most advanced surveillance data processing systems in the world.

"ARTAS now has 1.3 million operating hours and has demonstrate a remarkable level of reliability," said Jacques Dopange, director network management. "This is vital for an activity which is central to the safety of aircraft and their passengers."
