20170301987 · 2017-10-19 ·

A mechanically steered, horizontally polarized, directional antennae for aerial vehicles, such as UAVs. The antenna system can include a planar substrate with a horizontally polarized antenna embedded therein. A rotation member, on one end, can be attached to the planar substrate, and can extend from an external surface of the aerial vehicle. An actuator can be coupled to the rotation member to rotate the rotation member. A communication controller of the aerial vehicle can control the actuator to beam horizontally polarized radiofrequency (RF) waves to a target receiver or receive a wave front from a target transmitter.

CONTINUING ELECTRONIC MEDIA ENTERTAINMENT AFTER COMPLETION OF TRAVEL SEGMENT

Continuing electronic media entertainment on a personal electronic device (PED) after completion of a travel segment. Streaming characteristics for streaming of an electronic media item to a PED on board an aircraft via a first connection may be monitored and, if streaming of the remaining portion of the electronic media item will exceed the remaining travel time, trigger some or all of an excess portion of the electronic media item to be sent to the PED. The PED may store the excess potion in an access-controlled media file. After completion of the travel segment (e.g., at the destination location), the PED may resume playback of the electronic media item by obtaining a playback control code via a second, different connection. The second connection may be a different type of connection, or may be an indirect connection, in some cases.

Ground network for end-to-end beamforming

Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

Dynamic load balancing of satellite beams

A dynamic satellite load balancing system measures geographic position and travel information of in-flight aircraft in a fleet of aircraft equipped to establish in-flight connectivity services from a plurality of satellite beams. The in-flight aircraft include an on-board satellite map program with satellite map parameters to indicate which satellite beam of a group of available satellite beams is the most desirable based on the in-flight aircraft's geographic location. The system selects in-flight aircraft, determines load balanced satellite map parameters for the selected aircraft, and transmits the load balanced satellite map parameters to the aircraft to assemble load balanced satellite map programs to relieve wireless data communication saturation conditions on one or more of the satellite beams. The dynamic satellite load balancing system may transmit the load balanced satellite map parameters over an existing satellite data connection to make up-to-date adjustments to the communications load among the group of available satellite beams.

Dynamic time based product
09794815 · 2017-10-17 · ·

The system and method alters the data delivery service plan of a subscriber in response to a network degradation event that negatively affects the subscriber's plan during transportation (e.g. in flight). In response to the subscriber's request, the system and method grants the subscriber access to the in-flight network and/or data during the flight. Additionally, the system and method monitors and detects network degradation events during the flight. If an event occurs that negatively affects the subscribers plan during the flight, the system and method determines a time extension for the subscriber to access the network and/or data based on the duration of the network degradation event. The system and method also modifies the subscriber's plan based on the determined time extension and notifies the subscriber about the network degradation event and plan modification. The plan modification may credit the subscriber additional time, data, and/or services.

VIRTUAL WINDOW DISPLAY SYSTEM

A method and system are provided for generating imagery of a virtual window within an aircraft cabin. The method may be implemented using computer executable instructions, loaded onto a personal entertainment device (PED) for configuring the PED to link to an aircraft inflight entertainment system (IFE) and access imagery, such as imagery from at least one camera directed to an environment outside of the aircraft. The imagery is displayed on a surface visible to the passenger, and formatted to simulate an aircraft window.

DYNAMIC SIGNAL QUALITY CRITERIA FOR SATELLITE TERMINAL INSTALLATIONS

The described features generally relate to determining dynamic signal quality criteria for an installation of satellite terminals for communications in a satellite communications system. In particular, the signal quality criteria for an installation may be based on an identified position of the satellite terminal to be installed, and in some examples based on the positions and signal characteristics of neighboring satellite terminals that have already been installed. In some examples, a signal quality map may be generated for a service beam coverage area, based on predetermined transmission characteristics and/or measured transmissions from a number of satellite terminals served by a communications satellite. The generated signal quality map may then be used to determine a signal quality threshold for the installation of a satellite terminal being installed for communications in a satellite communications system.
