Bears next to no relevance to remote sensing capability compared with:
a) decoys + camouflage
b) mobility messes up look down time, even with a constellation of cameras targetted at Indian landmass (which china doesnt have and doesnt plan on having given the cost to benefit ratio).
c) geo-birds are on equator (if you want to solve look down time), relevant field of view/resolution is like asking cricket umpire to sit at the last row of a stadium and asking to detect the faintest knick of a ball. These are all mostly heavy comm birds with no cameras for that very reason.
