Think of each pixel. If you want 1m resolution, you need at least one pixel for every meter of the planet. And, satellites can't be told to stay over land only. So, how many satellites do you need in your constellation to keep a 1s refresh time?

The earth is 200 million miles^2 surface area.

So, no. I sorta remember 4 day refresh at 3m resolution was the "wish I could get to" goal.
