NON-TERRESTRIAL NETWORK SATELLITE BEAM SWITCHING
A method and apparatus for non-terrestrial network beam switching is provided. A non-terrestrial network base station includes a transmitter configured to transmit downlink data to user equipment and a receiver configured to receive uplink data from the user equipment. A channel bandwidth of the non-terrestrial network base station is divided into a plurality of bandwidth parts respectively corresponding to a plurality of geographic areas, and each bandwidth part is respectively associated with a satellite beam. When the user equipment is located in a first geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding first bandwidth part. After the user equipment transitions from the first geographic area to a second geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding second bandwidth part of the plurality of bandwidth parts.
Simplified Inter-Satellite Link Communications Using Orbital Plane Crossing to Optimize Inter-Satellite Data Transfers
In a method and apparatus for inter-satellite communications, transmissions between a satellite and neighboring satellites that share an orbital plane occur via an aft antenna or a forward antenna and transmissions between the satellite and neighboring satellites that do not share an orbital plane occur via the aft antenna or the forward antenna timed during orbital plane crossings. This occurs even if the total path length and number of links is higher than inter-satellite communications that use side-to-side transfers.

Meanwhile, the ground segment is configured to receive such messages and to route them to one or more destinations for aircraft monitoring. The resource scheduling system is configured to control the antenna systems of individual payloads to dynamically adjust the beams for receiving ADS-B messages of the individual antenna systems.
System for low-latency satellite communication handover
Satellites provide communication between devices such as user terminals and gateways to other networks, such as the Internet. Non-geosynchronous orbit satellites move relative to terrestrial user terminals, passing in and out of communication over time. To maintain ongoing communication, a handover takes place in which the responsibility to maintain communication with a particular user terminal passes from one satellite to another. To minimize disruption due to the handover, satellite motion and availability of communication resources are allocated in advance. Participating devices such as the user terminal, current satellite, and next satellite, are provided with details of the handover in advance. As a result, interruption in communication due to a handover from one satellite to another is substantially reduced.
