None of the space imagers you list are trying to grab 90 x 90 degrees FOV in a single frame,.....But then no one's trying to use the image in real time to operate an aircraft.
Indeed, and I never claimed they did.
So I don't see your comparison as relevant.
You said "
Resolution is my main concern (maybe interest is a better word) for these sensors." I'm attempting (and failing) to show that sensor resolution is a lousy criterion when making such a conclusion. There is LOTS more to consider in ANY imaging system than sensor resolution. This is akin to your "mediocre agility makes a bad fighter" argument. There is LOTS more to consider than agility when making such a conclusion.
You call it "Active Duty", fine by me.
That's nice, because that's what we call it in USN. And which incidentally has an entirely different meaning than the assumption you made. And it was your (false) assumption that is of significance here.
