I. Introduction
The on-orbit reconfiguration of satellite antennas has the potential to make Telecommunication and Earth Observation missions more versatile [1], [2], [3], [4]:
Coverages and satellite orbits can be modified in order to follow the market evolution.
The radiation pattern can be adapted to varying meteorological conditions, mitigating absorption losses by rain and snow [5], [6].
And also manufacturing and stability tolerances of deployable main reflectors can be made looser by compensating their shape errors at the sub-reflector level [7], [8].
