I've never bothered following the citations so I don't know how true this is, but it's pretty insane if it's real. A 100-meter-diameter satellite! I know it's an unfolding-umbrella-style mesh like you said, but still, that's impressive.

The giant unfolding umbrella antenna is not far off from what has been thoroughly commercially publicized for the unclassified commercial first and second gen Thuraya satellites (Boeing 702 bus).
