Abstract:
A method of steering a communications beam from a mobile platform, comprising:generating a table of beam steering data sets, said generating said table of beam steering data sets comprising: tiling a planetary surface into a plurality of cells; assign a latitude and longitude location address to each of the plurality of cells to establish cell geographical location information; associating a virtual planetary radius to each of the plurality of cells based on pre-loaded geographical data; and generating table of beam steering data sets based on the cell geographical location information established during the assigning of a latitude and longitude location address and the associating of a virtual planetary radius; looking up a data set from the table of beam steering data sets that corresponds to a received downlink address; adjusting a beam-pointing angle in response to the looked-up data set; and repeating looking up and adjusting at least one time based on the generated table of beam steering data sets.
