ARTAS is a system designed by  Eurocontrol  in order to help in  Aerial surveillance  and  Air traffic control . It can establish an accurate Air Situation Picture of all traffic over a well-defined geographical area (e.g.  ECAC ), and to distribute the relevant surveillance information to a community of user systems.

PHOENIX  is a multipurpose  Radar Data Processing System(RDPS)  /  Surveillance Data Processing System (SDPS)  -  a.k.a. tracker  - used for many ATC applications in the  Deutsche Flugsicherung  (DFS), and is continuously extended and maintained ever since. PHOENIX is also foreseen as a fundamental component for all future ATM systems in the DFS into the 2020s and part of the DFS initiative for “ATS componentware” in the European  SESAR  programme.
