  • Patent number: 6941111
    Abstract: A method for rapidly identifying which one of a plurality of mobile wireless terminals on-board a corresponding plurality of mobile platforms, such as aircraft, accessing a target transponded satellite, is causing interference with one or more non-target satellites orbiting in proximity to the target satellite. The method involves dividing the plurality of mobile wireless terminals into two groups and commanding one-group of terminals to stop transmitting. A check is then made to determine which group of terminals is causing the interference. That particular group is then subdivided successively by a factor of 2 and alternately checked to see if it is still causing the interference until a single mobile terminal is identified as the source of the interference.

  • Patent number: 6731909
    Abstract: A method for rapidly identifying which one of a plurality of mobile radio frequency (RF) terminals on-board a corresponding plurality of mobile platforms, such as aircraft, accessing a target transponded satellite, is causing interference with one or more non-target satellites orbiting in proximity to the target satellite. The method involves dividing the plurality of mobile RF terminals into two groups and commanding one group of terminals to stop transmitting. A check is then made to determine which group of terminals is causing the interference. That particular group is then subdivided successively by a factor of 2 and alternately checked to see if it is still causing the interference until a single mobile terminal is identified as the source of the interference.

  • Patent number: 4689625
    Abstract: A satellite communications system and method of communication which results in increased frequency-reusage within assigned frequency bands and allows for a reduction in satellite transponder requirements per unit of bandwidth employed. The disclosed system employs a satellite in a geostationary orbit having transponders and one or more large-aperture, high-gain antennas that provide a broad-area beam for a relatively wide service area and for transmitting to and receiving signals from N narrow-area beams for N respective sub-areas, the sub-areas corresponding to the high-traffic nodes. Both beam types operate in the same allocated frequency bands but with opposite linear or opposite handed circular polarizations, or, alternatively, with arbitrarily determined portions of the allocated frequency band pairs with dual polarization so that the allocated frequency spectrum is used at least N+1 times.
