At 1 px/m², the Earth's surface is 5×10^14 pixels, so with the full constellation of 10,000 satellites and 1 fps that'd be 5×10^10 pixels/satellite/second (about a terabit/satellite/second uncompressed). If you can shoot 30 images per second, you'd need a 1.6 gigapixel camera.
It's technically possible but not feasible.
