ABSTRACT:
A system for stabilizing two antennas on a mobile platform, the antennas including a first antenna associated with a first geo-stationary satellite and a second antenna associated with a second geo-stationary satellite, the system comprising an upper alignment system and a lower alignment system. The upper alignment system is configured for being a common support for the antennas. The upper alignment system has an intermediate element. The upper alignment system is configured for pointing the antennas relative to the intermediate element, such that the angular displacement between the antennas is matched with the angular displacement between the satellites. The lower alignment system is connected to the upper alignment system and the mobile platform. The lower alignment system is configured for maintaining the orientation of the intermediate element in order to compensate for rotation of the mobile platform, such that the antennas are maintained pointing toward their respective satellites.
