Geostationary orbits are definitely a thing. Haven't done the math but two should take care of it, one east and one west of the area you're trying to illuminate

Geostationary orbits are definitely a thing. Haven't done the math but two should take care of it, one east and one west of the area you're trying to illuminate and one should come out of the umbra before the other one enters.
edit: One might also take care of it if it could be far enough east. Would need to do the trig though.

- rtkwe 8y agoYes it would be orbiting above the equator but at GEO it can easily see all of China which is all it need to do to reflect light from the sun to Chengdu.
