- Abstract
PACS is one of the three instruments of the ESA space mission Herschel. Its warm electronics consists of 4 computers connected through 1355 links. Each computer is equipped with a DSP-21020 microprocessor, each running its own software. In this poster we describe the main features of the dierent software with some emphasis on the FDIR (Failure Detection Isolation and Recovery) procedures implemented on-board: we describe the FDIR design and we show how the few anomalies that occurred since the Herschel launch three years ago, have been succesfully handled autonomously by the instrument.
