Telemetry ground stations have to ensure missions with always growing complexity (reception from various data provider, increase of data load, distribution on several sites) making them more and more expensive to maintain. Their refurbishment is usually carried out by successive iterations in order to reduce costs and secure the integration of new hardware and software bricks. One major consequence is the appearance of heterogeneous data formats representing the same telemetry data (CH10 packed, unpacked, PCM Data + Clock, raw PCM over IP, TMoIP, Hardware proprietary format, etc.). This article describes architectures and methods we implemented in order to assure the most efficient BSS / BSC processing of those heterogeneous data formats with various data quality factors (as DQM, DQE), time desynchronization of the sources, allowing to provide, as a selection or as a combination of telemetry data, the best telemetry stream to the end user.
