hello all
I am flying here in winter, temperature is from 0C to -10C, contrasts are quite well. So if is cloudly, contrast decreases, but not dramatically. I incrased gain of thermopiles amplifier for 1200, this helps. We are flying on the sea - on ice, and one problem is near the city. Houses are warmer than ice and angles may be biased about 10 degrees.

All,
Antoine is right.  Jeremy and Aron(I was actually drinking wine with Antoine at the time) did a demo on the east coast of the US.  They flew up and down the coast, and then 1 mile out to sea to circle a ship, then back again, doing this for 1 hr.  I was told the navigation and overall vehicle response was great.  Consider that the ocean is probably 50F or so, and the sky is -40F so no problems there, the only issue would be going up and down the coast where the left and right may see a bias.  This loop is closed when the navigation error is presented do to the offset.  Of course, this is only true if you fly with the Z sensor :)

That's great news. Did they / will they only use IR sensors for attitude
control?
