Abstract:
Satellites In-Orbit Support is a complex activity requiring the daily thorough analysis of thousands of parameters. Performing this activity for the growing fleet of satellites delivered by Astrium, the space EADS subsidiary and leading European Satellite company, featured the development of a new generation processing environment: TELMA (standing for TELeMetry Access).
This paper describes TELMA and provides a detailed view of the technical choices that structured this system. First, it describes the notion of satellite telemetry and the needs of the In-Orbit Support (IOS) team. Then TELMA software architecture is detailed as well as system deployment aspects. This paper also provides lessons learnt about the development and deployment of the software. Finally, a status of the current version of TELMA is presented and perspectives are drawn.
