PrestoDecom: a portable software for house keeping telemetry decommutation
Gilles Picart, Martyn Smith · 2012
Access to housekeeping telemetry is recurrent throughout the whole life of a satellite. Flight control teams, spacecraft manufacturer engineers and subsystem experts are all interested in accessing telemetry parameters to make sure that the satellite is running nominally. This is usually fulfilled by a traditional web server embedded within the control centre which performs extraction and calibration of the raw telemetry. However, this centralized solution is usually available only at the beginning of the operations preparation. The raw telemetry which is produced outside the control centres, e.g. at the satellite supplier premises or on launch pads, is rarely exploited by experts who may miss useful information because of the lack of widespread extraction means. Hence the idea of developing a universal portable application called PrestoDecom offering the same facilities as those inside a control centre, allowing work on raw telemetry archives anywhere, especially when the control centre is inaccessible. This innovative software was successfully used in 2003 to validate the satellite simulator on the PROTEUS multiplatform project. PrestoDecom has been rapidly adopted inside CNES by a growing user community conquered by its simplicity and efficiency. Today 2/3 of CNES satellite projects have already invested into PrestoDecom and
