A LEO satellite should remain in view for 10 minutes average, that's what you get with starlink.
The idea is to launch a entire swarm of them like starlink.
The execution is trivial, they just have a large mirror.
In practice, it will only work up to like 3h past sunset or before sunrise, past that you might struggle with full coverage and brightness will be reduced.
The problem is that the mirror has to be giga efficient and unimaginably flat with very few imperfections, or it will be dim and scatter the light. The sun is basically a laser, because it is so fucking far away, all the light is traveling in exactly the same direction. With a perfect mirror, the light will all bounce off and continue all in a straight direction and hit the earth with a beam of light the exact dimensions of the mirror. That's the general idea.
