摘要： An antenna system of a satellite may consist of an antenna receiver that is coupled to a plurality of flexible couplings. The couplings may each be affixed to one or more antenna elements. The couplings may be deployed in space in an uncontrolled manner. Additionally, the spacing between the couplings, and in turn the antenna elements, may be spaced in an uncontrolled manner. The antenna elements may have no pointing requirements. The antenna system may receive training signals and associate an antenna element to a time of arrival based on the training signal. Upon receiving a data signal, the antenna system may apply coefficients determined from the association of the antenna element to the time of arrival to the data signal to discover wanted signal coherence among the antenna elements.

摘要： Technology is described for providing electronic offering items to passengers on an aircraft. In one example of the technology, destination information may be obtained from an aircraft data bus that receives aircraft flight information from a plurality of aircraft information systems located on the aircraft. The destination information may be sent to a vendor application programming interface (API) to obtain at least one electronic offering item associated with the destination information to display in an inflight entertainment system. An electronic offering item may be received via the vendor API, and the electronic offering item may be sent to a client device to be displayed via the inflight entertainment system. A graphical interface of the inflight entertainment system at the client device may enable a passenger on the aircraft to interact with the electronic offering item.

摘要： A method for pointing an antenna can include positioning, by a positioner, a beam of an antenna mounted on a vehicle to an initial angular position towards a target satellite based on an initial pointing direction for the antenna, the initial pointing direction being defined in a fixed reference plane and communicating, from the antenna, a signal with the target satellite, wherein the positioner controls an orientation of a pedestal of the antenna. The method also includes, executing, by an antenna control unit (ACU), an offset compensation operation of the antenna. The offset correction operation can include adjusting a pointing direction of the antenna to a plurality of angular positions and selecting a scan offset angle based on measured signal metrics for the plurality of angular positions. The method can include calculating a yaw compensation of the antenna based on the initial pointing direction and on a yaw pointing direction.

摘要： Methods, apparatuses, and systems for two-way satellite communication and an asymmetric-aperture antenna for two-way satellite communication are disclosed. In one embodiment, a beam pattern for an asymmetric-aperture antenna is offset in a narrow beamwidth direction, and the offset beam pattern is directed by a mechanical gimbal, with the beam pattern offset made to reduce interference with an adjacent satellite. In additional embodiments, operational areas near the equator are identified for a given offset beam pattern, or a beam pattern offset may be adjusted over time to compensate for movement of the asymmetric-aperture antenna when attached to an airplane, boat, or other mobile vehicle.

摘要： Methods and systems establish a traffic policy for a personal electronic device based on one or more physical characteristics of the device. In some aspects, a database of traffic policies is maintained. The traffic policies are for accessing a network via a wireless communications link. A network access unit receives a request from a personal electronic device to access the network. The request is analyzed to determine a physical characteristic of the device. A traffic policy is established from the database for the device based, at least in part, on the determined physical characteristic of the device. Transmission of network traffic for the device is then scheduled based at least in part, on the established traffic policy.

摘要： Approaches are described for providing quality of experience (QoE) driven in-transport communications services. For example, in-transit communications services are provided over a network to content consumption devices on one or more transport craft. During a measurement window, delivery of the in-transit communications services can be measured to obtain network-level delivery (NLD) measurements, and consumption of the in-transit communications services by one or more of the content consumption devices can be measured to obtain customer-level consumption (CLC) measurements. The NLD and CLC measurements can be used to compute a QoE score that indicates a delivered quality of service as perceived by one or more passengers of the one or more transport craft. The QoE score can be used to update stored service level data. The update can cause generation of one or more service level triggers, which can trigger automatic remedial action to address QoE-related conditions.

摘要： In an exemplary embodiment, a phased array antenna comprises multiple subcircuits in communication with multiple radiating elements. The radio frequency signals are independently adjusted for both polarization control and beam steering. In a receive embodiment, multiple RF signals of various polarizations are received and combined into at least one receive beam output. In a transmit embodiment, at least one transmit beam input is divided and transmitted through multiple radiating elements, with the transmitted beams having various polarizations. In an exemplary embodiment, the phased array antenna provides multi-beam formation over multiple operating frequency bands. The wideband nature of the active components allows for operation over multiple frequency bands simultaneously.

摘要： An artificial magnetic conductor (AMC) antenna apparatus includes a ground plane and a flexible antenna element layer above the ground plane. The ground plane includes a conductive base surface, a plurality of memory metal wires, and a frequency selective surface (FSS) layer above the base surface, where the FSS layer includes a plurality of conductive patches separated from one another. Each of the memory metal wires electrically connects one of the conductive patches to the base surface. Each of the memory metal wires is rigid in a memory-shaped state, causing the FSS layer to be fixedly spaced from the base surface during operation of the AMC antenna apparatus. The memory metal wires are each flexible in a non-memory-shaped state, enabling the FSS layer to be collapsed towards the base surface when the antenna apparatus is stowed.
