EOBT is Estimated Off Blocks Time : The flight plan time for the flight to be ready for departure. ATC usually allow a tolerance of +/- 15 minutes. TOBT, Target Off Blocks TIme , is a more accurate measure, usually within +/- 5 minutes, which tells the local CDM system and NMOC Brussels when the airline believes a flight will be ready. From this, a TTOT is calculated (Target Take Off Time) , which may be adjusted to allow for departure separations, CTOT etc, and then working backwards will provide a TSAT (Target Start Approval Time) which will provide both ATC and the airline the most suitable start up time given all the factors that the local CDM system takes into account.

ASTERIX  (short for  All Purpose Structured Eurocontrol Surveillance Information Exchange ) is a standard for the exchange of  air traffic services  (ATS) information. It is developed and maintained by the  European  ATS organization  Eurocontrol . ASTERIX not only stands for All-Purpose Structured Eurocontrol  Surveillance   Infor mation  Exchange but also represents a state-of-the-art surveillance  data  format which is nearly being adopted by the world users  community  as the universal  standard  in this  domain  today

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.
