One aspect disclosed features a method, comprising: controlling a multi-band satellite terminal capable of receiving signals on a plurality of frequency bands to receive a signal transmitted by a satellite on a first frequency band of the plurality of frequency bands; determining link conditions of the first frequency band based on the received signal; generating an estimate of link conditions of a second frequency band of the plurality of frequency bands, wherein the estimate is generated based on the link conditions of the first frequency band; selecting the second frequency band based on the estimate of the link conditions of the second frequency band; and controlling the multi-band satellite ground terminal to receive the signal transmitted by the satellite on the second frequency band.

A satellite antenna ground station service includes a plurality of ground stations and associated data centers, wherein the data centers are part of a provider network. Clients may reserve satellite antenna access time-slots via a user interface of the satellite antenna ground station service and store data directly to a data center of the provider network or to the client's premises via a direct connection between the client and the provider network. In some embodiments, the provider network may offer a plurality of network-based services, such as a compute service, a data storage service, a machine learning service, or a data analytics service, and a client may utilize one or more of these services to analyze and process downlinked data received from a satellite of the client via a satellite antenna ground station of the satellite antenna ground station service of the provider network.

Within a satellite communications system, a base station communicates with standard compliant user equipment (UE) via a satellite having a field of view. The base station has a processor that instructs the satellite to generate a wide beam signal covering a plurality of cells in the field of view, and detects an access request from a user equipment within the plurality of cells over the wide beam signal. The base station, comprising a processing device such as an eNodeB, then generates one or more network broadcast/access signals that is uplink to a satellite and broadcasted via one or more nominal beams generated by the satellite, covering all the inactive cells, one of the plurality of cells having the access request.

A system of architecture, apparatus and calibration method is invented for high-power flexible-polarization payload for satellite communications. The system comprises onboard phase-tracked apparatus, flexible polarization mechanism, and in-orbit calibration method. The power combining and polarization performance of the phase-tracked payload is monitored on ground by measuring the cross-polarization discrimination (XPD) and/or axial ratio (AR). The high performance over the life is achieved by optimization of the XPD or AR on ground and adjusting complex gain of the transponders. The high-power flexible-polarization in-orbit-calibration payload may be applied but not limited to UHF, L, S, C, X, Ku and Ka-band high power satellite systems.

Various arrangements for monitoring and enforcing multi-tier throughput assignments in a network, such as satellite-based communication network, are presented. Throughput usage may be monitored on a beam-level, satellite-level, gateway-level, and system level. Throughput usage for individual satellite terminals may be aggregated and used to determine the throughput usage on an entity-by-entity basis. An entity can have one or more sub-entities to which throughput is allocated. Excessive throughput usage for higher-tier entities can result in throughput being restricted for satellite terminals associated with lower-tier entities.

Systems, methods, and computer-readable media for processing a digital bit stream representative of a communication signal are provided. The method can include dividing, at one or more processors, the digital bit stream into a plurality of data packets, each having an overlap of data from an adjacent packet. The method can include performing a timing recovery operation and a carrier recovery operation on portions of the plurality of data packets in multiple processing blocks in the processor, in parallel. The method can include combining the first plurality and the second plurality based on timing and phase stitching.
