4D-aerospace research and simulation

4D-Aerospace Research and Simulation GmbH (4DAE) has been established August 2008 as a Spin Off Company of the University of Salzburg, Computer Science. For the time being the Head Office is located in the TechnoZ Salzburg. Dr. Carl-Herbert Rokitansky (CEO) is mainly responsible for all technical and research issues, Josef Mörtl takes care of all economy matters as a managing director.

4DAE deals with all aspects of simulation and analysis of future aeronautical and railway concepts. 4D-Aerospace signals 3-dimensional awareness in which time as a 4th dimension expresses exactness and future visions.


Carl-Herbert Rokitansky (CEO)

Carl-Herbert Rokitansky  studied economics / mathematical statistics at the University of Vienna and Computer Sciences at the University of Vienna and Technical University of Vienna (1977 – 1982). From 1983 to 1986 and from 1987 to 1988 he was within “Institut für Nachrichtentechnik” at DFVLR (former name of DLR) Oberpfaffenhofen near Munich. During academic year 1986/1987 he was Visiting Professor at University of Lawrence, KS, USA.(From 1988 to 1991 he was within the “Institut für Datenverarbeitungstechnik” at “Fern-Universität Hagen”, Germany. Since 1991 he is within the Institute of Communication Networks, RWTH Aachen University of Technology, Aachen, Germany.
He is  H.-Professor for „Technical Informatics“ at University of Salzburg, Institute (FB) for Computer Sciences where – since 1989 – he is giving lectures on mobile communication, stochastic modeling and simulation, performance analysis using Markov chains, encryption and data security. At University of Salzburg, Prof. Rokitansky established the „Aerospace Research“ Group which contributed already significantly in the development and performance evaluation of digital aeronautical communication systems, as well as benefit assessment of future ATM/ATC procedures and enhancements, including decision support solutions towards automated systems.
