Only US has spy satellites in coalition unless you count France which has SPOT. 4 KH11 & 1 Lacrosse are the usually quoted numbers, but these identifications are more uncertain than they are sometimes made out to be. KH11 are photographic, Lacrosse is radar. > 4) What sort of resolution? > Can they count buildings? (Yes, it seems) yes. > Can they count vehicles? (maybe?) yes. > Can they recognise different types of vehicles? yes. c.f leaked pictures of planes, ships. > Can they count men? reports suggest that they can, at least approximately. > Can they see an Iraqi soldier scratching his nose? Probably not. > 5) Are they affected by the dark, or by cloud cover, or is much of the > sensing done in the Infra Red? Radar isn't, apparently, I think IR will be affected by cloud cover though. Maybe somebody who knows about weather satellites can help. > 6) Can they really detect missile and airplane launches, > or is this done by AWACS? Only the geostationary (DSP) early warning satellites do this, q.v Aviation Week a couple of weeks ago. > 7) A point was made that if you knew when the satellite was due, you could > simply hide under a bridge for 10 minutes.

Depends on how good friends they remain with Russians, at a guess ? > 8) Any other information which is available about spy satellites. Go to library and do author search under D. Ball, J. Richelson & W. E. Burrows. Enjoy. Nick --
