Due to the special adversities in the work environment, the application field space travel has an especially high demand and requirements for telematics technologies. Zentrum für Telematik e.V. focuses in this segment on the remote control of exploration robots and the application of small satellites in clusters. Several small satellites are operated in cooperation with the University of Würzburg. Clusters of small satellites provide the potential for a paradigm change from large, expensive satellites to clusters of distributed, cost effective standard satellites, which means that a significantly faster and more flexible realization of the satellite mission is possible. Many of the methods and technologies developed for space travel can also be transferred to industrial applications.
