摘要： A satellite is provided, including an onboard computing device. The onboard computing device may include a processor configured to receive training data while the satellite is in orbit. The processor may be further configured to perform training at a machine learning model based at least in part on the training data. The processor may be further configured to generate model update data that specifies a modification made to the machine learning model during the training. The processor may be further configured to transmit the model update data from the satellite to an additional computing device.

摘要： Methods and systems are described for providing end-to-end beamforming. For example, an end-to-end beamforming system include a relay satellite and a ground network to provide communications to user terminals located in user beam coverage areas. The ground network includes geographically distributed access nodes and a central processing system (CPS). Beamformers of the ground network generate forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the satellite, produce forward downlink signals that combine to form forward user beams.

摘要： Disclosed herein are systems and methods for private communications networks. In various embodiments, a communication system in accordance with the disclosed technology includes a private communications network that has earth stations configured to communicate with a multi-spot beam satellite. The earth stations are communicatively unreachable by communication sources that are remote from the earth stations and that are outside the private communications network, and the earth stations are distributed across geographies covered by different spot beams of the multi-spot beam satellite.

摘要： Apparatuses, methods, and systems of hub communication with a satellite network or a terrestrial network are disclosed. One method includes detecting presence of the satellite network, detecting, by the hub, presence of a terrestrial network, selecting to connect to one of the satellite network or the terrestrial network based on a priority ruleset, estimating a propagation delay between the hub and a base station of the satellite network when the satellite network is selected, adjusting a timing offset between transmit and receive radio frames at the hub based on whether the satellite network or the terrestrial network is selected, and based at least on the propagation delay, and communicating with the base station of the satellite network or a base station of the terrestrial network.

摘要： 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.

摘要： In one embodiment, a communicating device (e.g., either a ground station server or a particular distributed module of a satellite communication system) mitigates congestion on a particular return communication path via an intermediate satellite from the plurality of distributed modules to the ground station server. In particular, in response to determining that the level of congestion is above a threshold, then the communication device mitigates the congestion by, e.g., one or both of either a) determining an uncongested return communication path from a particular distributed module to the ground station server, ensuring that the uncongested return communication path would not interfere with any unintended receiver, and then causing the particular distributed module to use the uncongested return communication path, and b) enforcing one or more communication restrictions on a utilized return communication path to reduce the effect of a communication on the overall congestion of the utilized return communication path.

摘要： Techniques for improving data rates at mobile terminals that are subject to periodic channel interruptions in a beyond-line-of-sight communication system are disclosed, including improved encoding and decoding systems that identify blockages and modify receiver operation during blockages to reduce data errors. In certain embodiments, encoding, symbol mapping, interleaving, and use of unique periodic identifiers function to enable a series of packets that may be received in a blockage impaired channel with reduced errors.

摘要： A method is provided that can include designating as a control node, a first communication node of a plurality of communication nodes associated with a satellite communications system. The method can include, designating as a listening node, a second communication node of the plurality of communication nodes. The listening node is responsive to instructions provided by the control node. The method includes receiving, at a tuning module, one or more input tuning factors, wherein the one or more input tuning factors can include at least a resource burden factor. Responsive to receiving the one or more input tuning factors, the method includes adjusting by the tuning module, one or more tunable output parameters. The method includes sending, from the control node to the listening node, instructions comprising one or more of the tunable output parameters, and executing the instructions at the listening node.
