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.

Abstract: In one aspect, an apparatus for wireless power transmission comprises a plurality of coils and a controller. The controller is configured to sequentially energize each coil of the plurality of coils to produce a magnetic field. The controller is configured to select a subset of the plurality of coils based on a measure of coupling between each coil of the subset of the plurality of coils and at least one receiver coil of a chargeable device. The controller is configured to sequentially energize pairs of coils selected from the subset of the plurality of coils. The controller is configured to select at least two coils from the subset of the plurality of coils for wireless power transmission based on a measure of coupling between each of the pairs of coils and the at least one receiver coil of the chargeable device.
