A commonality of all space missions is the need to receive, process, archive, and analyze on-board telemetry of the spacecrafts involved. For long-running missions, the amount of data that needs to be preserved can reach hundreds of gigabytes. At the German Space Operations Center (GSOC), the RootVis framework is under development; it shall allow to process the full telemetry dataset of the GSOC satellite missions for analysis of the long-term behavior of the spacecraft. Typically each mission has slightly di�erent concepts of analysis, visualization and format of its telemetry, so RootVis was conceptualized as a modular telemetry visualization tool. It is built around the core telemetry archive in the �le format of the ROOT data analysis library, which|thanks to its e�cient serialization| enables high performance data access. Thus, it is possible to handle large data sets with billions of data points in short time for all current and future GSOC missions.
