pie_: yes to gyro in general. I think mems are more common than optical.
<pie_>
and probably full og ITAR
<pie_>
*of
<pie_>
sagnac is apparently super duper accurate though
<pie_>
also its mentioned that mechanical gyros are accurate to within 10 meters or something on ICBMs, i find that kinda crazy
<awygle>
It's all about bias stability as I understand it
<awygle>
And maybe Allan variance?
<pie_>
*shrug*
<awygle>
I was only peripheral to ADACS but those are my memories
<awygle>
Kalman filter corrects most things pretty well
<awygle>
PlanetLabs' whole architecture is based on "lots of crappy sensors combine to an OK spacecraft" lol
<pie_>
lol
<awygle>
You have to be careful with mems for space, depending on the mechanism they're either great or terrible in radiation
<pie_>
the problem is im dreaming of ghetto price cubesat launch (beg for a piggyback) and then dreaming of fancyass hardware i will neher have th emoney or manufacturing capability for, but hey :P
<awygle>
Lol yup yup
<pie_>
dont acknowledge it x'''D
<pie_>
the local physics department actually has some historical experience with radiation testing but sadly thats basically died out :(
<pie_>
there was a really good nuclear physics group but i think it kind of just mostly dissolved over time
<pie_>
they did some kind of neutron resistance testing for CCDs used for detector alignment at CERN's CMS, but thats basically all i know about that :P
<pie_>
though i think this was back in the 90s heh

I've done testing at hospitals and I know of people who've done it at dairy farms
<pie_>
hehe
<pie_>
i doubt ill have the resources for a second engineering model, but that might actually be something interesting to play with; experimentally radiation testing hardware/software
<pie_>
though i doubt theres much new work to do in that area

there's probably always room for hardening research
