CHAMP-ISDC - The IT Project for Satellite Missions B. Ritschel, S. Wendt, M. Schneider Data Center, GFZ Potsdam, Telegrafenberg A3, D-14473 Potsdam The kernel of design, architecture and implementation of the CHAMP- Information System and Data Center (CHAMP-ISDC) will be used for new state-of-the-art ISDCs for new (LEO) satellite missions. A major precondition for the realization of that ambitions aim is a component based architecture of the ISDC application, generated by an user driven object-oriented software live cycle. The whole system development process from the user requirements analyse via the generating of a component based software architecture towards to the implementation of prototyps and the finished system is presented.
