A New Offline Data Processing System for TanDEM-X and TerraSAR-X Mission

Abstract

In contemporary and future spacecraft systems, it is of highest interest that the downloaded house-keeping data can be accessed very fast as all subsystem engineers rely on these data. For this purpose a new offline telemetry processing system has been developed by GSOC’s sub-contractor CAM Systems for TerraSAR-X and TanDEM-X project and further future missions. The experience gained with the current TerraSAR-X offline processing system showed that the performance of this system is not sufficient to fulfill all tasks satisfactory. For the follow-on project TanDEM-X the demands for fast data access are very stringent due to the requirements of the formation flight of the two spacecraft. The new processing system is much more powerful than the existing system in terms of processing time due to parallel processing and intelligent distribution of processing tasks on virtual machines. This paper describes the Mission Offline Processing System (MOPS) in basics.
