Management of "Future Products" in the Distributed Payload Ground Segment for TerraSAR-X

Abstract

The German Remote Sensing Data Center (DLR-DFD) has developed the Data and Information Management System (DIMS) as a distributed multi-mission infrastructure which will be reused within the TerraSAR-X Payload Ground Segment. Besides other requirements like large data volume, time and reliability constraints a major issue is the management of "future products" throughout the system. For TerraSAR-X DIMS has to support the ordering of user specified future acquisitions, to handle the interface to Mission Planning, to control the subsequent reception of corresponding raw data and to manage the processing and delivery of the derived products. The requested features will be incorporated into the existing modular components in a way that they are reusable also for further missions. The paper describes the concept of DIMS how to integrate the “satellite in the loop” and how to meet the additional requirements in a distributed system.
