20110304496	EFFECTIVE MARINE STABILIZED ANTENNA SYSTEM - An effective marine stabilized antenna system, in terms of antenna to radome size and antenna/RF performance complies with all relevant worldwide SatCom regulations. The combination of a dual offset Gregorian antenna (DOGA) with a stabilized polarization over elevation over tilt over azimuth pedestal, and a control/stabilization algorithm, ensures antenna orientation restrictions guarantee compliance with side-lobe intensity regulations. Operating a dual offset Gregorian antenna substantially within a pre-determined antenna cut range of a 45 degree angle relative to a configuration of the antenna and a relative position of a target provides antenna performance that complies with applicable SatCom regulations, despite having to flip the antenna 90 degrees to continue tracking the satellite.	12-15-2011
20110057849	DYNAMIC POLARIZATION ADJUSTMENT FOR A GROUND STATION ANTENNA - A ground station antenna includes a LNB with at least one dipole, a feed horn, a waveguide between the LNB and the feed horn, and a rotation mechanism. By rotating a portion of the waveguide, the polarization of an electromagnetic wave propagating between the LNB and a satellite is transformed to match the polarization to (one of) the dipole(s) and to an antenna on the satellite. Another ground station antenna includes a main waveguide, two mutually orthogonal branch waveguides, a coupling mechanism for coupling two orthogonal antenna dipoles to the proximal end of the waveguide, and a transformation mechanism that transforms the polarization of an electromagnetic wave propagating between the branch waveguides and a satellite via the antenna dipoles to match the polarization to one of the branch waveguides and to an antenna on the satellite.	03-10-2011
