This was pointed out to me, thought it was interesting: Space Assigned Numbers Authority (SANA) Note that it lists "Ku band". I looked up Directv-15 and the only entries for it show "Ka band" - even though that satellite also had reverse band and Ku payloads. So I think maybe this only refers to a satellite's primary mission instead of all bands it broadcasts/receives on. We already knew that either T16 goes to 101, or it goes to 103 and D15 goes to 101. Since it is designated as Ku here it looks like it probably goes to 101. I wonder if it might be a smaller simpler Ku only satellite, so they can build it faster and try to get it launched and operational before the end of next year for the MPEG2 SD cutoff? Hopefully before long we'll find out when in 2019 this is planned to happen.
