You need to move the point from one horizon to the other. Like the sun, satellites “rise” on one side and set on the other. All of that in less than 15min(in LEO).
That depends on its orbit. If you’re pumping enough heat into the satellite, you can just aim it at a point in its path. Because space is a good insulator, it wouldn’t lose that much heat each orbit.

You can watch the dishes turn.
