    摘要: A dynamic satellite map updating 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 updated satellite map parameters for the selected aircraft, and transmits the updated satellite map parameters to the aircraft to assemble new satellite map programs to relieve wireless data outage conditions on one or more of the satellite beams. The dynamic satellite updating system may transmit the updated 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.

    摘要: Methods and systems for free space communication comprising one or more satellites that may provide a continuous communication link between two or more terminals are disclosed. A first satellite may be configured to send and/or receive data signals from a first terminal through a first link, and a second satellite may be configured to send and/or receive data from a second terminal through a second link. The first satellite and the second satellite may be coupled through a crosslink. The satellites and the terminals may be positioned at a minimum latitude threshold in order to take advantage of the decreasing circumference of the earth at increasing latitudes. The system and the method may comprise dividing the communication pathway between into a plurality of smaller segments, which when linked together approximate an optimal pathway for low latency and enable maintaining of higher bandwidth between the two terminals.

    摘要: Systems and methods for providing mobility across satellite beams, are described. The system includes a first core node, a second core node in communication with the first core node at layer-2 of the OSI model (L2), and a first gateway in communication, at L2, with the first core, the first gateway configured to provide access to a first spot beam at a first location. The system further includes a second gateway in communication, at L2, with the second core node, the second gateway configure to provide access to a second spot beam at a second location, and a mobile device, at the first location, in communication with the first gateway via the first spot beam, wherein the mobile device is assigned an IP address by the first core node. The mobile device moves from the first location to the second location. Further, the first gateway, in response to the mobile device moving from the first location to the second location, notifies the second gateway, through the first core node and the second core node, that the mobile device is moving to the second location, and transmit the session information to the second gateway, and the second gateway, in response to the notification, maintains connectivity with the mobile device using the IP address.

    摘要: Methods, systems, and devices are described for managing satellite communications through the deployment of a fleet of multi-beam satellites serving overlapping and non-overlapping spot beams. In these methods, systems, and devices, a first communication service associated with a relatively wider spot beam of a first satellite is provided to a first coverage area having multiple terminals. A second communication service associated with a relatively narrower spot beam (e.g., high-gain spot beam) of a second satellite is provided to a second coverage area located within the first coverage area. A subset of terminals located within the second coverage area is identified, and the terminals of the identified subset are transitioned from the first communication service of the wide spot beam of the first satellite to the second communication service of the high-gain spot beam of the second satellite.
