ABSTRACT:
An articulated device to be used for pointing satellite antennas, especially of data relay or like telecommunication satellites. It comprises at least three articulations rotatable about their respective axes coupled in pairs by arms. These rotation axes intersect at a remote virtual rotation center coinciding with the antenna's focus. The device allows pointing of an antenna by moving its reflector, while maintaining the antenna feed at its focus, thus avoiding antenna radiation pattern distortion.
