IMINT satellites are never GEO (if only because GEO is so far), so they don't "sit above" some area but fly over it at high speed, so it can get a 45° or 30° pi

IMINT satellites are never GEO (if only because GEO is so far), so they don't "sit above" some area but fly over it at high speed, so it can get a 45° or 30° picture and the only issue is the target is a bit further than when you're straight above it.
