Patent number: 11973575Abstract: Embodiments provide high-throughput, hub-and-spoke satellite communications with geographically non-overlapping user beams and full frequency reuse. For example, a coverage area of a satellite is segmented into multiple candidate coverage zones, and an associated consumption demand is determined for each candidate coverage zone. Fixed spot beams are assigned to a subset of the candidate coverage zones according to highest associated consumption demands, such that each fixed spot beam corresponds to at least one candidate coverage zone to service an associated beam coverage area that is geographically non-overlapping with beam coverage areas of all other fixed spot beams, and each fixed spot beam is allocated full use of a same spectrum. One or more steerable beams selectively cover lower consumption demand zones.Type: GrantFiled: July 9, 2021Date of Patent: April 30, 2024Assignee: Viasat, Inc.Inventors: Anil Agarwal, Remberto Martin, Erwin Hudson, Clifford Burdick

Patent number: 10784954Abstract: Embodiments provide techniques for dynamic spot beam assignment in a geostationary satellite communications network. For example, a ground processing node in the geostationary satellite network can monitor spot beam coverage area location and can detect a beam drift trigger indicating present drifting of one or more coverage areas. Ground terminals can be identified as serviced by spot beams associated with the drifting coverage area(s) and as experiencing a signal quality impact from the drifting. The ground terminal node can compute an update to a beam assignment map having a reassignment of the identified user terminals from their presently servicing spot beams to another of the spot beams in a manner that seeks to address at least some of the signal quality impact identified as associated with the drifting. Some embodiments further account for load balancing, and/or other factors, and/or can maintain stateful communications between the reassigned user terminals and the geostationary satellite.Type: GrantFiled: March 1, 2018Date of Patent: September 22, 2020Assignee: VIASAT, Inc.Inventors: Donald Becker, James Petranovich, Remberto Martin

Patent number: 7925208Abstract: A payload design for a multi-spot-beam satellite communication system includes a plurality of uplink spot beam receivers and downlink spot beam transmitters, and a broadcast transmitting subsystem capable of transmitting a broadcast beam to an entire system geographical service area. An input filter-switch-matrix (IFSM) controllably selects input IF signal bands for routing to an on-board digital signal processor-router (DSPR). The DSPR subsequently routes all received point-to-point and broadcast data packets to the appropriate downlink spot or broadcast transmitting subsystems for transmission thereof. The broadcast downlink allows broadcast transmissions to occur at the highest efficiency possible, while also allowing for flexible provision of surge capacity for point-to-point transmissions on previously exhausted spot beams by selective use of the broadcast beam for such point-to-point transmissions.Type: GrantFiled: October 28, 2003Date of Patent: April 12, 2011Assignee: The DIRECTV Group, Inc.Inventors: Jamal Sarraf, Edward J. Fitzpatrick, James E. Justiss, Remberto Martin, Michelle J. Glaser-Weiner

Publication number: 20060181455Abstract: A device for measuring the received signal strength at an Earth station antenna has the capability to provide an accurate pointing indication when the frequency bands and other key characteristics of the satellite signals are not uniform over the coverage area. The device has an input port, a plurality of passive or active signal filters, a filter selector and an output port. The device may further contain a signal amplifier with automatic or manual gain control. A plurality of filters is provided which may be coupled singularly or in combination between the input port and the output port. Each filter or combination of filters is associated with a particular geographic area and capable of allowing the satellite signal assigned to that geographic area to pass while attenuating or blocking other signals, noise and interference. The filter selector is used to connect the appropriate filter or combination of filters between the input port and the output port.Type: ApplicationFiled: February 15, 2005Publication date: August 17, 2006Inventors: Erwin Hudson, Remberto Martin
