First Claim
1. A process for cooperative aerial inter-antenna beamforming for communication between (a) multiple moving platforms, each platform having an aerial antenna mounted thereon, such that the aerial antennas have variable positions and orientations over time, and (b) at least first and second user antennas connected to user equipment having a lower altitude than the aerial antennas;
- determining the positions of the aerial antennas to within 1/10th of a wavelength of signals between the aerial antennas and the first and second user antennas;
the process involving transmitting data relating to the positions and orientations of the aerial antennas to a processing system, the processing system calculating and transmitting beamforming instructions to the aerial antennas, the aerial antennas thereby transmitting or receiving respective first component signals for the first user antenna, and transmitting or receiving respective second component signals for the second user antenna; and
the first component signals each having essentially the same information content but differing in their phase and usually amplitude, the second component signals each having essentially the same information content but differing in their phase and usually amplitude, so as to form a first cooperative beam from a cooperative sum of the signals between the aerial antennas and the first user antenna, and a second cooperative beam from a cooperative sum of the signals between the aerial antennas and the second user antenna.

Abstract
A process for cooperative aerial inter-antenna beamforming for communication between (a) multiple moving platforms, each platform having an aerial antenna mounted thereon, such that one or more aerial antennas have variable positions and orientations over time, and (b) first and second antennas connected to user equipment having a lower altitude than the aerial antennas; the process involving transmitting data relating to the positions and orientations of the aerial antennas to a processing system, the processing system calculating and transmitting beamforming instructions to the aerial antennas, the aerial antennas thereby transmitting or receiving respective first component signals for the first user antenna, and transmitting or receiving respective second component signals for the second user antenna, the first component signals each having essentially the same information content but differing in their phase and usually amplitude, the second component signals each having essentially the same information content but differing in their phase and usually amplitude, so as to form a first cooperative beam from the cooperative sum of the signals between the aerial antennas and the first user antenna, and a second cooperative beam from the cooperative sum of the signals between the aerial antennas and the second user antenna.

2. An apparatus for providing a communication network, for communication between (a) multiple moving platforms, each platform having an aerial antenna mounted thereon, such that the aerial antennas have variable positions and orientations over time, and (b) first and second user antennas connected to user equipment having a lower altitude than the aerial antennas;
-
