A communications system comprising: radio frequency equipment configured to generate RF beams from a high altitude communications platform providing communications coverage over a coverage area , wherein said RF beams comprise at least a first RF beam and a second RF beam ; a beamformer configured to apply beam weights to said RF beams to divide said coverage area into service areas arranged in a frequency reuse ground pattern , wherein said first RF beam has a first beam pointing direction directed at a first service area when said high altitude communications platform is at a first position along a flight path, and said second RF beam has a second beam pointing direction directed at a second service area ; and a processor configured to: adjust said beam weights to compensate for beam displacements resulting from motion of said high altitude communications platform along said flight path , wherein said processor is further configured to adjust a beam weight of said first RF beam to compensate for a beam displacement of said first RF beam in response to said high altitude communications platform moving to a second position along said flight path; and interchange said RF beams to maintain said frequency reuse ground pattern throughout said flight path, wherein said second RF beam is replaced by said first RF beam having said first beam pointing direction directed at said second service area. radio frequency equipment configured to generate RF beams from a high altitude communications platform providing communications coverage over a coverage area , wherein said RF beams comprise at least a first RF beam and a second RF beam ; a beamformer configured to apply beam weights to said RF beams to divide said coverage area into service areas arranged in a frequency reuse ground pattern , wherein said first RF beam has a first beam pointing direction directed at a first service area when said high altitude communications platform is at a first position along a flight path, and said second RF beam has a second beam pointing direction directed at a second service area ; and a processor configured to: adjust said beam weights to compensate for beam displacements resulting from motion of said high altitude communications platform along said flight path , wherein said processor is further configured to adjust a beam weight of said first RF beam to compensate for a beam displacement of said first RF beam in response to said high altitude communications platform moving to a second position along said flight path; and interchange said RF beams to maintain said frequency reuse ground pattern throughout said flight path, wherein said second RF beam is replaced by said first RF beam having said first beam pointing direction directed at said second service area. adjust said beam weights to compensate for beam displacements resulting from motion of said high altitude communications platform along said flight path , wherein said processor is further configured to adjust a beam weight of said first RF beam to compensate for a beam displacement of said first RF beam in response to said high altitude communications platform moving to a second position along said flight path; and interchange said RF beams to maintain said frequency reuse ground pattern throughout said flight path, wherein said second RF beam is replaced by said first RF beam having said first beam pointing direction directed at said second service area. <EOS>
