Abstract: A system for receiving a signal from one or more satellites or for transmitting a signal to one or more satellites and a method of operating the system, the system comprising a frame, a signal converter for converting between a received/transmitted signal and a corresponding signal, the converter being positioned, in relation to the frame, rotational around a predetermined axis, and a depolarizer mounted, in relation to the frame, rotational around the predetermined axis, the method comprising the sequence of steps of rotating one of the converter and the depolarizer independently of the other of the converter and the depolarizer, fixing the depolarizer in relation to the converter at a predetermined rotational relationship and rotating both the converter and the depolarizer.

Abstract: A self-stabilizing antenna is pivotable about an axis of elevation, a cross-level axis and an azimuth axis. The antenna comprises an antenna member (1) for transfer of signals between said antenna member and a satellite, and a frame member (6) on which the antenna member (1) is mounted for mounting thereof on said movable support. The frame member (6) includes mounting members (7, 8 and 9) permitting pivotal movement of the antenna member about said axes. The antenna further comprises driving units (12, 14) for pivotal movement of the antenna member (1) about said axes, electronic units (21, 22) for sensing and controlling the pivotal movements of the antenna member (1) and for the transfer of signals between the antenna member and a satellite, a signal transformer unit (5), a signal amplifier unit (23), a signal transfer unit (30) and a gyroscope unit (24).
