The tradeoff of course is lower resolution. If each pixel is 50m, a USN carrier will be a 6x2 set of pixels, not easy to distinguish from other large ships like tankers and cargo ships of similar size. If you want higher resolution, you will have to orbit closer (e.g. LEO). But to orbit closer, you will have to use a highly inclined orbital period and cannot stay over the same spot on earth, meaning to actually observe the same spot on earth nearly continuously, you will need a constellation of similarly orbited satellites.
