> How hard is the beam steering relative to everything else? > It's a weighted sum of the antenna signals (as with any phased array), so the cost is the extra arithmetic to do this (on a per-satellite basis). The weights can be computed open-loop from the positions of the satellites, provided you're interested only in gain and not antijam performance. The multiple antenna elements, downconverters, and ADCs add to the expense somewhat, of course.
