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. This binary technique of successively subdividing all of the terminals into smaller and smaller subpluralities allows the terminal which is causing the interference to be quickly identified from a large plurality of terminals accessing the target transponded satellite.

Method and apparatus using a binary search pattern for identifying an interfering mobile terminal

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. This binary technique of successively subdividing all of the terminals into smaller and smaller subpluralities allows the terminal which is causing the interference to be quickly identified from a large plurality of terminals accessing the target transponded satellite.
