Patent ID: 7463206

Claim:
A self-stabilizing antenna which is pivotable about an axis of elevation (A), a cross-level axis (B) and an azimuth axis (C) and which is adapted for mounting on a movable support, wherein 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 said antenna member on said movable support, said frame member including mounting members ( 7 , 8 and 9 ) permitting pivotal movement of the antenna member about said axes (A, B, C), and wherein the antenna further comprises at least one or more driving units ( 12 , 14 and 19 ) for pivotal movement of the antenna member ( 1 ) about said axes (A, B, C), one or more 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 unit ( 5 ) for, inter alia, transforming the signals from the satellite, a unit ( 23 ) for amplifying the signals from the satellite, a unit ( 30 ) for transferring the signals from the satellite from said signal transformer unit ( 5 ) to said signal amplifier unit ( 23 ), and a gyroscope unit ( 24 ), wherein the units ( 5 , 12 , 14 , 19 , 21 , 22 , 23 , 24 and 30 ) forming part of the antenna are provided such that more than 50% of the total mass of the antenna is concentrated to the antenna member ( 1 ) and/or to the frame member ( 6 ) in direct connection with the antenna member.
