An alert message identifying a problem communication link is transmitted to a subset of the plurality of satellites. In response to receiving the alert message, subsequent data packets are routed through the communication network by the satellites using their respective routing table to avoid the problem communication link.

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.

A cellular network management system manages terrestrial base station communications and orbital base station communications with user equipment to provide wireless service and allocate links among terrestrial base stations and orbital base stations according to base station availability determined from state space predictions.

A method provides packet transmission of data between two terminal devices via at least one flying object. The flying objects are moving within a given swarm of flying objects and the flying objects are disposed in a grid being characterized by a number of flight paths. One flying object from the swarm of the flying objects is determined to be a reference flying object and each of the flying objects is assigned a position. Coordinate values of a receiving flying object within the swarm of the flying objects is derived from a respective data packet being transmitted. A number of sequential single transmissions for a transmittal of data between a transmitting flying object and the receiving flying object is performed. Each single transmission within the swarm of the flying objects occurs only between two respective flying objects which are topologically neighboring and in direct communication with each other.

An on-board method for the end-to-end transparent transport of data packets is implemented by a telecommunications system comprising a first, sending station, a second, receiving station, a first, sending satellite, connected directly to the first station, and a second, receiving satellite, connected directly to the second station, the first satellite and second satellite being interconnected via a spaceborne network. The transport method comprises steps allowing an end-to-end transparent adaptive control loop for the adaptive control of the modulation and of the coding of the access links between the first station and the first satellite and between the second station and the second satellite to be implemented.

A method for transparent on-board routing of data packets at high bit rate is implemented by a telecommunication system comprising an origin transmitting station, a first destination receiving station, a second destination receiving station, and a plurality of at least two satellites. The origin transmitting station segments high bit rate data streams into coded or uncoded packets each having the structure of a coded or uncoded DVB-S2 baseband frame BBFRAME; and the origin transmitting station inserts, for each segmented BBFRAME packet, coded or uncoded, an on-board routing label of a single piece respectively associated with the coded or uncoded BBFRAME packet. The on-board routing label contains an identifier of the destination receiving station associated with the coded BBFRAME packet, out of the first destination receiving station and the second destination receiving station.

The disclosed technology relates to systems and methods for tasking satellite constellations. A method is disclosed herein for receiving, from a resource database of a satellite control system, knowledge data corresponding to a plurality of components associated with a satellite constellation communications system. The plurality of components can include one or more satellites associated with a constellation. The method includes processing the knowledge data according at least one received mission objective. Processing the knowledge data can include determining a status of at least one satellite in the constellation. The method includes scheduling the satellite control system based at least in part on the received mission objective and the processed knowledge data; initiating communication with the at least one satellite in the constellation according to the scheduling; receiving updated status information for at least one component of the plurality of components; and storing, in the resource database, the updated status information.

Systems, methods, and software described herein provide enhancements for orbital satellite platforms. In one example, an orbital satellite platform includes a plurality of satellite devices each comprising a virtualized execution system configured to execute one or more software payloads as associated virtual nodes. An active satellite device is provided among the plurality of satellite devices and is configured to execute at least an active virtual node, determine state information related to the execution of the active virtual node, and periodically update the state information in a storage satellite device.
