"The resolution is a linear function of their height..."
Incorrect. Even in the consumer camera space, resolution is a function of distance, native sensor resolution, lens magnification, lens quality, shutter speed (because the target is moving), stability of the tripod, etc. Same thing is true of orbital imagery: your effective resolution is a function of your optics, your sensor, the ability of your attitude control system to hold a steady pointing vector, etc.
Also, "capability" != "resolution". What frequency bands is that satellite imaging in? Visible, SWIR, LWIR, ultraviolet? What is the effective magnification of its optics? Is it an optical system at all, or is it an RF bird? Is it all of the above? Does it just take top down snapshots, or can it track moving targets? If the latter how fast can it track? Fast enough to keep up with a tank, or fast enough to keep up with a fighter plane? How many frames per pass can it take? How fast can it slew to get multiple objects in the same pass? Etc.
