Patent number: 11979221Abstract: Systems and methods are described for enabling flexible signal pathways within a satellite of a satellite communications system. For example, a pathway selection subsystem in a bent-pipe satellite enables a flexible arrangement of non-processed signal pathways that couple uplink antenna ports with downlink antenna ports via uplink and downlink pathway selectors. The pathway selectors can be dynamically reconfigured (e.g., on orbit), so that the configuration of the pathway selectors at one time can form one set of signal pathways between respective uplink and downlink antenna ports, and the configuration at another time can form a different set of signal pathways between respective uplink and downlink antenna ports. The pathway selection subsystem can have a simulcast mode which, when active, couples each of at least one of the uplink antenna ports with multiple of the user downlink antenna ports to form one or more simulcast signal pathways.Type: GrantFiled: August 24, 2022Date of Patent: May 7, 2024Assignee: VIASAT, INC.Inventors: Aaron J. Mendelsohn, Donald Becker

Publication number: 20240129026Abstract: Systems and methods disclosed herein for pointing a steerable antenna system (22) onboard a satellite (10) exploit advantageous image-processing techniques that provide a computationally-efficient and accurate way of determining the pointing error of the steerable antenna system (22) and determining corresponding pointing corrections. Received-signal power measurements for individual array elements in an antenna array of the steerable antenna system provide the basis for forming a power-distribution image (70) that reveals where an uplink signal (42) falls on the array (50), which in turn provides a basis for determining the appropriate pointing correction.Type: ApplicationFiled: March 22, 2022Publication date: April 18, 2024Inventor: Aaron J. Mendelsohn

Publication number: 20230224030Abstract: Systems and methods for supporting more flexible coverage areas and spatial capacity assignments using satellite communications systems are disclosed. A hub-spoke, bent-pipe satellite communications system includes: terminals; gateways; a controller for specifying data for controlling satellite operations in accordance with a frame definition including timeslots for a frame and defining an allocation of capacity between forward and return traffic. The satellite communications system may employ a satellite with a feed array assembly and may use on-board beamforming or ground-based beamforming. Beam hopping within timeslots of the frame may be used to provide coverage to different cells in different time periods. The flexible coverage areas may be provided using changes in satellite position, antenna patterns, or beam resource allocations.Type: ApplicationFiled: January 12, 2023Publication date: July 13, 2023Inventors: Mark J. Miller, Charles N. Pateros, Aaron J. Mendelsohn, Donald L. Runyon

Patent number: 10574342Abstract: Systems and methods are described for paired-beam satellite communications in a flexible satellite architecture. Embodiments include one or more “bent pipe” satellites having multiple transponders for servicing a number of spot beams. Implementations include novel types of paired-beam transponders that communicatively couple gateway terminals and user terminals in different spot beams. Some implementations also include loopback transponders that communicatively couple gateway terminals and user terminals in the same spot beam. The transponders can use similar components, can provide for flexible forward-link and return-link spectrum allocation, and/or can provide other features. Certain embodiments further include support for utility gateway terminal service and/or redundancy (e.g., active spares) for one or more active components.Type: GrantFiled: March 18, 2019Date of Patent: February 25, 2020Assignee: VIASAT, INC.Inventors: Aaron J.
