    Abstract: Disclosed is an antenna including a lens; a feed trolley configured to couple to a feed; a track coupled to the feed trolley; a flexible member connected to the feed trolley configured to move the feed coupled to the feed trolley along the track to a first destination or to a second destination, wherein the feed is configured to move along the track to the first destination to form a first collimated beam through the lens to point to a first satellite, and wherein the feed is configured to move along the track to the second destination to form a second collimated beam through the lens to point to a second satellite. In various examples, the antenna includes a second feed trolley and a second feed, and the track includes two sides to accommodate a feed trolley on each side.

    Abstract: Aspects of the disclosure provide a handoff procedure for a satellite communication system such as a broadband low-Earth orbit (LEO) satellite communication system. A gateway and a user terminal (UT) coordinate and schedule a satellite-to-satellite handoff in such a way that there are no messaging round-trip delays between the last return service link (RSL) packet transmitted from the user terminal to the source satellite and the first RSL packet transmitted from the user terminal to the target satellite. Therefore, an outage on the return link (from the user terminal to the gateway) can be limited to the actual time for moving the antenna feed from the source satellite to the target satellite. Furthermore, an outage on the forward link (from the gateway to the user terminal) can be limited to a single round-trip delay in addition to the time for moving the antenna feed.

    Abstract: A beam pattern of a base station antenna is refined when communicating with multiple aircraft, so that interference to adjacent beams from the base station are reduced. The method include receiving position locations from each of multiple aircraft. The method also include the receipt of an attitude of each of the aircraft as well as receipt of measurements of the pilot signals from each of the aircraft. The pilot signals were transmitted by the base station. The method also include the adjustment of an amplitude and a phase of a signal driving at least one antenna transmit element to refine the beam pattern. The adjustment is based at least in part on the pilot measurements, the position locations, and the attitude of each of the aircraft.

    Abstract: Methods and apparatuses for wireless inductive power transfer are described herein. One implementation may include an apparatus for wireless inductive power transfer. The apparatus comprises a primary resonator configured to wirelessly transfer power to a secondary resonator coupled to a load of a wireless power receiver. The apparatus comprises a coupling circuit configured to couple energy from a source power supply to the primary resonator. The apparatus comprises a controller configured to coordinate an adjustment of a first amount of coupling between the source power supply and the primary resonator, via the coupling circuit, with an adjustment of a second amount of coupling between the secondary resonator and the load of the wireless power receiver. The coupling circuit comprises a first coupling loop comprising a plurality of segments, each configured to be selectively electrically connected to the source power supply, the first coupling loop electrically isolated from the primary resonator.

    Abstract: A method and apparatus for establishing a communication link between a user terminal and a first satellite associated with a first satellite service are disclosed. The user terminal determines a position of the user terminal based, at least in part, on location information provided by a satellite positioning system (SPS) receiver associated with the user terminal, determines a reference azimuth of the user terminal based, at least in part, on a position of a second satellite associated with a second satellite service that is different than the first satellite service, obtains ephemeris data for the first satellite, and aligns a directional antenna of the user terminal with the first satellite based, at least in part, on the position of the user terminal, the reference azimuth of the user terminal, and the received ephemeris data.
