Which Instruments on Herschel and Planck run RTEMS?

I cannot comment on Planck, but to my knowledge the Data Processing Unit on all three instruments on Herschel (HIFI, PACS and SPIRE) are running something like Virtuoso.

For Safari, a Infra-Red instrument (candidate) for the Spica satellite, will be running RTEMS on at least two controllers (Data Processing Unit and Mechnisms Control Unit) and perhaps even on a third (Detector Control Unit).
