Parabolic Steam Generators versus PV

Yes, the GEO SPS is what I know phased array steering from. You seem to have a concern about distance, but this is primarily about fine steering. Gross steering would be pointing the antenna emitter at the direction of the Earth, and then phased array beam steering would provide the fine steering needed to hit the rectenna. I don't think anything in this process is particularly sensitive to distance (other than that the beam is a bit wider at greater distances).

What is phased array steering and a pilot beam? From a glance online it looks like maybe the antenna can change what it's transmitting based on the distance to the rectenna at the time, is that right? It seems the phased array steering and pilot beam are used for the GEO SBSP, but they would be able to handle the widely varying distances during lunar/Earth rotation?
