Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for channel bonding in an adaptive coding and modulation mode. In some implementations, a system receives packets of a data stream for transmission in a satellite communications system. The system determines a modulation and coding arrangement for the received packets. The system generates code blocks that include data from the packets of the data stream. The system assigns the generated code blocks for transmission on different carriers. One or more of the different carriers is operated in an adaptive coding and modulation mode to support multiple modulation and coding arrangements within a single carrier. The system transmits the code blocks on the different carriers using the determined one or more modulation and coding arrangements.

A communication system has a control module with a control processing device, and a plurality of common modules. Each of the common modules has a common processing device. The control module and the plurality of common modules are connected with at least one adjacent common module to form a communication array. The control module and the common modules communicate via a first routing path having a first path of common modules of the plurality of common modules, and a second routing path having a second path of common modules of the plurality of common modules different than the first path of common modules. The control module and the plurality of common modules communicate via the second routing path when one of the first set of common modules fails.

A method of communicating with multiple satellites includes allocating, based on one or more conditions corresponding to a plurality of spatial channels associated with multiple satellites, each subset of a plurality of subsets of antenna resources of a phased array antenna to a respective different satellite included in the multiple satellites. The method also includes commanding one or more transceivers to establish simultaneous communicative connections to the different satellites via the allocated subsets of antenna resources, and re-allocating, based on a detected change to at least one of the one or more conditions, at least one antenna resource to a respective another different satellite. The method also includes commanding the one or more transceivers to maintain the simultaneous communicative connections to the different satellites using the re-allocated at least one antenna resource.

Described herein are systems, methods, media, and devices for generating a satellite program for contacting satellites. In some embodiments, data including one or more targets for accessing a satellite constellation is obtained. Based on the data, a set of representations may be generated and candidate satellite constellation access programs may be determined based on the set of representations. For each program, a first score may be computed for each target to obtain a first set of scores, and a second score may be computed for each first score of the first set of scores to obtain a second set of scores. A satellite constellation access program may be selected from the candidate satellite access programs based on the second set of second scores.

A method for estimating, at one and the same given time, a set of attenuations of one or more first radiofrequency RF uplinks, implemented by a VHTS space telecommunications system. In an auxiliary usage step, an on-board regenerative or digital transparent processor DTP generates at least one beacon signal that is or are distributed, in the Q band, to N nominal access stations GWn(i) in order to be measured in terms of power, or measures the spectral power of each traffic signal transmitted by the nominal access stations GWn(i), i varying from 1 to N. In a following step, the attenuation levels An(i) of the uplinks LUn(i) are determined based on the powers of the one or more beacon signals that are measured on the corresponding downlinks LDn(i) in the Q band, or based on the one or more spectral powers, measured by the DTP, of the traffic signals received on the one or more uplinks LUn(i).

The request information is associated with a task to be completed by at least one satellite asset among a plurality of satellite assets, where the satellite assets are grouped into a plurality of constellations and each of the constellations is associated with a corresponding scheduler among a plurality of schedulers. The method also includes assigning the task to a queue. The method further includes determining at least one specified scheduler to schedule the task at the at least one satellite asset. In addition, the method includes sending instructions to the at least one specified scheduler for performing the task by the at least one satellite asset.

The present teachings is generally directed to facilitating satellite and terrestrial internet communications. In some embodiments, configuration information for configuring a communications device may be retrieved. The configuration information may be provided to the communications device, and the communications device may be caused to be configured based on the configuration information. Responsive to receiving a first data signal from a first satellite, the communications device may be configured to generate and output a second data signal based on the first data signal, the first data signal including first data encoded using one or more space-based communication protocols, and the second data including second data encoded using one or more terrestrial-based communication protocols.

A method performed by a network node (160) includes serving a cell area by a first physical network node for a first time duration. The first physical network node uses an identifier of a logical network node. For a second time duration, the cell area is served by a second physical network node. The second physical network node uses the identifier of the logical network node. The first physical network node serves the cell area with a first frequency band and the second physical network node serves the cell area with a second frequency band.

The present invention discloses a satellite-based blockchain architecture, including a terrestrial blockchain miner network, a constellation system, and a consensus protocol coordinating the constellation system and the terrestrial blockchain miner network. In each round, a satellite generates an oracle, and satellites broadcast the oracle to the terrestrial blockchain miner network. The oracle selects a terrestrial miner as a winner of the current round based on a specific rule. The winning terrestrial miner has the right to generate a new block in the round, and broadcasts the new block to other miners by using the terrestrial blockchain miner network. Other miners receiving the new block check the validity of the block, and if the check succeeds, the block is broadcast to other miners by using the terrestrial blockchain miner network. The present invention significantly improves the efficiency and throughput of a blockchain, and optimizes and reduces the energy consumption of executing a consensus protocol by a terrestrial blockchain miner network.

A radio communication system for transmitting data to a ground station includes plural stochastically distributed orbiting satellites with plural antennas traversing a portion of the earth's surface divided into zones. The ground station has a unique address identifying itself and the zone where it is located. A local area network associated with the ground node includes at least one satellite that stores the identity of a satellite antenna paired with a ground station antenna to form a radio link for transmitting data onboard the satellite to the ground station. Other satellites in the local area network store the ground node address and the identity of an antenna paired with an antenna in another satellite that also has stored the ground node address. A wide area network includes at least one satellite, each of which stores the identity of an antenna paired with an antenna of another satellite that has stored the ground node zone to form at least one inter-satellite radio link. If a satellite with data onboard is not in a local area network associated with the destination ground node or a wide area network, the satellite transmits the data toward the ground node zone.
