| titleOfInvention | Process and apparatus for communicating with user antennas |
| abstract | A process for performing coordinated over-the-air inter-antenna beamforming for communication between (a) a plurality of mobile platforms and (b) at least one antenna mounted on user equipment, each platform having an an aerial antenna such that the aerial aerial has a position and orientation that is variable over time and the user equipment has an altitude lower than the aerial aerial; the process includes comparing the location and the aerial aerial with the aerial aerial. The orientation-related data is transmitted to a processing system, which computes beamforming instructions and transmits them to the aerial antennas, which transmit or receive the corresponding component signals for each user antenna therefrom. The component signals of the antennas have substantially the same information content but their phases and usually amplitudes are different so as to form coordinated beams from the coordinated summation of the signals between the aerial antenna and the user antenna. A method of determining the position of a mobile aerial antenna or antenna element mounted on at least one mobile platform such that the aerial antenna has a variable position and orientation over time, the method Including: determining the phase difference yi between signals of known wavelength λi, the phase difference being a fraction of the wavelength with a value between 0 and 1, the signals at (a) i ground-based transmitters and ( b) transmitting between the aerial antennas or antenna elements, the ground-based transmitter may be a backhaul base station, where i is at least three, and the ground-based transmitter has a position known to be within λi/10 , thereby confirming the distance from the base station to the aerial antenna or antenna element as λi(ni+yi), where ni is an unknown integer; the position of the aerial antenna or antenna element is approximated by differential GPS or other methods Determined to be within a small number of wavelengths λi, thereby determining that ni can be one of a finite number of possible integer values for each signal; the number of base stations and their locations are sufficient to allow for the elimination of limited differences with ni from other ground-based transmitters the number of possible values of ni that do not agree, until only one integer value is established for each ni; by triangulating the air antenna or antenna element at a known distance λi(ni+ yi) to determine the position of the aerial antenna or antenna element. |
