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： Various aspects of the disclosure relate to handoff (e.g., idle mode handoff or other types of handoff) for a user terminal. In some aspects, a user terminal (UT) may request idle mode handoff information from a ground network (GN). Idle mode handoff information may include, for example, start times for a set of satellites, whereby each particular start time indicates when the UT may handoff to the corresponding satellite. The UT may send the request for idle mode handoff information to the GN when the UT has a defined number of valid entries (e.g., one unexpired entry) remaining in an idle mode handoff table. In some aspects, the idle UT may send the request for idle mode handoff information to the GN based on a time associated with a particular entry in an idle mode handoff table or based on a time of validity of an idle mode handoff table.

摘要： A non-geostationary satellite is configured to provide a plurality of spot beams that implement a first frequency plan at Earth's Equator and a second frequency plan away from Earth's Equator. The second frequency plan is different than the first frequency plan. In one embodiment, the non-geostationary satellite is part of a constellation of non-geostationary satellites, with each of the satellites providing spot beams that implement a first frequency plan at Earth's Equator and implement a second frequency plan away from Earth's Equator as the satellites travel in orbit around Earth.

摘要： Systems and methods are described that use the downlink and uplink frequency bands of the fixed satellite service (FSS) and direct broadcast service (DBS) systems to provide broadband access to aerial platforms including aircraft, drones, and unmanned aerial vehicles (UAVs) such as balloons. The secondary service aerial platform transmitters are configured to avoid interference into the primary satellite service receivers. The aerial platform may be able to detect and connect to the cell site with the strongest signal. The aerial platform may be able to handoff from one cell site to another. Systems and methods are described that provide broadband access to ground terminal via aerial platforms such as drones and UAVs such as balloons.

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.
