It’s called a geosynchronous orbit. Meaning that its position is always the same relative to the Earth’s surface, which coincidentally makes satellite like this much harder to use as a weapon since you can’t move it anywhere. You could however “point” to almost any location in a particular hemisphere of the Earth. This has the trade off of increasing the distance which the energy must travel also decreasing its effectiveness as a weapon since there will be energy loss do to that travel.
