Sounds like that's a fundamental risk assessment that needs to be made ASAP. If you're talking $1 million satellites, and this denigrated state of the art most powerful rad hard CPU board goes for a reported $200K, then if the non-tested, non-rad hard (and don't forget temperature extremes), more powerful CPUs just don't work, or don't work for certain missions, you need to find that out.
- Retric 12y agoThese systems are not designed by idiots. Normal CPU's don't last long enough in space to be all that useful for satellites. And even for profit telecom companies stick with radiation hardened CPU’s so it's not like this is a case of 'military' over engineering.
- hga 12y agoAs far as I could tell, the low budget amateur radio types also use rad hard CPUs in their satellites. So, what's Mr. Lewicki's alternative?
