[QUOTE="popolon, post: 907025, member: 323681"] But for dish pointing, that signal would have effect when satellite is more moving up/down? Signal variation due to this movement. And how is footprint( spotbeam covered area size) not changing with this up/down movement, is the beam really dynamically making smaller when in upper position, and then bigger when lowest position? I mean if the spot beam is then always illuminating same area? Or is it illuminating more area when in upper position, as that would be logical? and when lower position, then illuminating smaller area? So fringe footprint would be affected (null line movements during day cycle and the position and size of the second side lobe) ? [/QUOTE]
