Title: Automated analysis tools for reducing spacecraft telemetry data

Conference ·
OSTI ID:10190105

A practical description is presented of the methods used to reduce spacecraft telemetry data using a hierarchial toolkit of software programs developed for a UNIX environment. A project requiring the design, implementation and test flight of small, lightweight spacecraft was recently conducted. This spacecraft development required hundreds of tests and integrations of subsystems on several special purpose testbeds, with each test creating large amounts of telemetered data. This paper focuses on the automated analysis and reduction of data which is telemetered from one of the key subsystems, the Probe. A typical telemetry stream from a testbed run averaged 50 Megabytes of raw data, containing over 1600 system variables. The large telemetry file (raw data) sent from the Probe was decoded and decomposed into a large number of smaller Break Out Files (BOFs) containing variables with timestamps, and image files.
