the sat recon birds which were alluded to are typically on very high apogees, and may (or may not) work in the visible spectrum.
geostationary is pointless for a recon sat (unless its a weather bird) as you can only take a picture of a limited area. so unless you want to look at a particular area constantly for a long time, most of the sorts,of assets that would be useful would be non geostationary.
