- jandrese 7y agoIt's a Russian built system from the 90s, so think embedded system type interface. The hardware is probably rad-hardened 80s era chips. It has an important job, but that job doesn't necessarily require a ton of CPU cycles or oceans of memory.

It says this about the DMS-R: "Another example is EADS DMS-R, a computer board based on ERC32 (Atmel TSC695) processor, and a fault-tolerant TMR version using 3 boards for the ATV of the ISS (Autonomous Transport Vehicle of the International Space Station)." I looked up the Atmel chip and it is a radiation hardened implementation of the SPARC v7 architecture. I was a little surprised it wasn't a RAD6000, since I saw elsewhere that BAE was involved. Their RAD line of hardened Power PC processors is quite popular in spacecraft systems. https://webee.technion.ac.il/~ran/papers/SurveySpaceProcessors.DASIA2012.pdf https://webee.technion.ac.il/~ran/papers/SurveySpaceProcesso...
