|One of the problems facing the Americans in terms of their intelligence on Iraq is their Keyhole satelites (about £1.3billion each). Although with excellent definition thought to be able to read newspaper headlines (which is probably a bit of an understatement as Israels cheaper ones can read numebr plates). The times of each pass are well publicised on the net (with amatuer astronomers posting times etc on websites USA 116, USA 129, and USA161), so it does not take an amateur sleuth to tell the Iraqi's when and when not to move their stuff. This has led to much specuation about the US producing an 'invisible' keyhole satelite (presumably non reflective material or something), which can hover over a target. But how to do this
The basic physics say you can have a geosynchronous orbitat 40,000km, or an eliptical orbit (90mins per orbit), leaving not a lot of timeover the country, so this satelite (s?) probably have a Molniya orbit which leaves them over target for a far larger period of time than a plain orbit more egg shaped 175-625 KM), and are a lot closer than a geosynchronous orbit.
