ARTAS makes use of proven multi sensor tracking technology to deliver an outstanding level of accuracy and reliability using PSR, SSR, Mode-S, WAM and ADS-B (both Terrestrial & Space-Based) surveillance sources to build an accurate air situation picture for air traffic management purposes.
What differentiates ARTAS from any other SDPDs is the overall concept of a distributed system, consisting of an assembly of identical units that can all coordinate together and act as one region-wide integrated surveillance system.
In addition to this, ARTAS is a one-fit-all solution for EMSOs, flexible enough to fulfil many operational needs.
One feature that permits this is the Tracker Tuning Areas. These are polygons that can be configured to apply dedicated tracker tuning, through parameterisation, thus enabling one ARTAS to satisfy tracking aircraft according to their operational service requirements.
The various surveillance sensors are connected to a Regional Surveillance WAN (wide area network) and the units are also connected to this network. Each ARTAS unit processes surveillance data received on the network and acts as a server, through the EUROCONTROL Surveillance Data Distribution System (SDDS), providing continuous aircraft track data to the ATC units and other systems (e.g. terminal areas, military, flow management units, etc.) that are connected to the network.
The seamless integration of all units allows for the application of 5NM separation minima throughout the covered area, including the transfers of traffic from one ATC unit to the next. 3NM separation may also be applied, following an in-depth operational evaluation of the ARTAS behaviour in local environments.
