Abstract: A method for determining a frequency usage pattern of one or more satellites includes receiving, at data processing hardware, identifications of one or more satellite communication frequencies used by a satellite at corresponding locations of the satellite along a non-geostationary satellite orbit. The method includes determining, by the data processing hardware, a pattern of frequency usage by the satellite at the corresponding locations of the satellite. The method also includes instructing, by the data processing hardware, communication between a high altitude platform and a ground terminal using an identified satellite communication frequency during a non-interfering period of time based on the pattern of frequency usage by the satellite. The high altitude platform has an altitude lower than the satellite.

Abstract: A phased-array antenna assembly includes an antenna board stack, a radome configured to cover the antenna board stack, and a casing configured to support the antenna board stack. The antenna board stack includes a central core, a bottom antenna unit defining a bottom thickness between a bottom surface of the central core and a bottom end of the antenna board stack, and a top antenna unit defining a top thickness between a top surface of the central core and the top end of the antenna board stack that is substantially equal to the bottom thickness. The bottom antenna unit includes two spaced apart bottom metal layers each associated with a different distance from the axis of symmetry. The top antenna unit includes two spaced apart top metal layers each associated with a corresponding one of the distances from the axis of symmetry associated with the bottom metal layers.

Abstract: A method for active interference avoidance in unlicensed bands. The method includes receiving an electromagnetic signal having a transmission frequency, a transmission period, and an antenna pattern from a phased array antenna. The method also includes switching the transmission frequency from a first transmission frequency with a first signal to interference and noise ratio to a second transmission frequency with a second signal to interference and noise ratio, wherein the second signal to interference and noise ratio is lower than the first signal to interference and noise ratio. The method further includes selecting a transmission period based on a time when a least amount of signal noise is present on the transmission frequency and selecting an antenna pattern that reduces interference on the selected transmission frequency.
