The on-board software of the HERSCHEL/PACS instrument: three successful years of in-flight operations

摘要

PACS is one of the three instruments of the ESA space mission Herschel. Its warm electronics consists of 4computers connected through 1355 links. Each computer is equipped with a DSP-21020 microprocessor, eachrunning its own software. In this poster we describe the main features of the dierent software with some emphasison the FDIR (Failure Detection Isolation and Recovery) procedures implemented on-board: we describe the FDIRdesign and we show how the few anomalies that occurred since the Herschel launch three years ago, have beensuccesfully handled autonomously by the instrument.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
