  • Demand assigned spatial multiplexing in satellite communication systems
    Patent number: 6625129
    Abstract: The methods (300, 900, and 1200), and apparatus (140 and 800) of the present invention employ demand assigned spatial multiplexing in a satellite communication system (100) to efficiently accommodate varying demand for high data rate service while minimizing satellite antenna and radio system complexity in a ubiquitous coverage satellite system optimized for transporting packet data. In a preferred embodiment, the methods (300, 900, 1000 and 1200) and apparatus (140 and 800) of the present invention use a first set of signaling beams (210) to establish signaling uplinks and then direct traffic spot beams (220) at particular UE devices to support traffic uplinks in accordance with demand assigned multiple access (DAMA) parameters when and only when the UE devices have traffic data to transmit to a satellite.

  • Hybrid geostationary and low earth orbit satellite ground station antenna
    Patent number: 6175340
    Abstract: A hybrid geostationary and low earth orbit (LEO) ground station antenna provides a geostationary receive antenna (30) which generates a narrow receive antenna beam for use with geostationary satellites. The ground station antenna can be either manually positioned so that the normal boresight of the antenna is directed toward the geostationary satellite serving the subscriber, or may be positioned using a cradle (170) which provides motion in the pitch, roll, and yaw axes. The ground station antenna also includes a LEO receive antenna (40) and a LEO transmit antenna (50) which receive which communicate with LEO satellites by way of wider beam, lower gain antenna beams. The geostationary receive antenna (30) is used in conjunction with the LEO satellites and during operations which involve communication with both types of satellites.

  • Multiple-tier satelite communication system and method of operation thereof
    Patent number: 6078810
    Abstract: A method and apparatus have been described for combining multiple satellite constellations into a cooperative network. A GEO tier of satellites receives information to be broadcasted to earth. The GEO tier receives the information from global hubs, regional hubs, and local hubs. Local program material is combined with regional and global program material by either the regional hub or a GEO satellite.
