Patent number: 11711140Abstract: An apparatus and method are disclosed for mitigating pointing errors resulting from satellite antennas. Reports are received from terminals in a beam hopping satellite communication system, and a pointing error associated with a satellite antenna is determined. The best beam for communicating with each terminal is selected based on the pointing error. A beam list containing the instantaneous traffic demand of terminals for each beam in the system is generated. An active beam set is then selected from the beam list for transmitting data during the next hop in the satellite communication system.Type: GrantFiled: December 29, 2020Date of Patent: July 25, 2023Assignee: Hughes Network Systems, LLCInventors: Stan Kay, Udaya Bhaskar

Patent number: 7619968Abstract: A communication system balances message traffic between return channel groups and within the groups, so that the user does not control the specific transmission frequency used. Uplink frequencies and bandwidths for the return channels are set by the system in a return channel control message in the broadcast signal so as to account for system and return channel group loading, and to account for user message backlogs. An initial transmission from a remote user may be made using an ALOHA-type burst signal that provides a message backlog to the control station, and is made on a frequency determined from a randomly weighted, load-based frequency selection process. The system, and not the individual users determine the frequency and channel allocations. For large backlogs or priority users, periodic bandwidth is provided.Type: GrantFiled: September 14, 2004Date of Patent: November 17, 2009Assignee: Hughes Network Systems, Inc.Inventors: Frank Kelly, Robert Kepley, Stan Kay

Patent number: 7386310Abstract: A satellite communications system having a fallback mode of operation, during which uplink signals are transmitted at a reduced data rate, is provided with a novel fallback mode ingress/egress mechanism utilizing a combination of a feedback-based fade detection scheme and fade detection based on parameters independent of the uplink signal transmission. The fallback mode ingress/egress mechanism is responsive to a satellite beacon signal independent of the uplink signals and to feedback signals produced by the satellite in response to the uplink signals, for requesting a satellite terminal to switch into the fallback mode when either the feedback signals indicate an increase in a fade level or in response to a first value of a selected parameter of the satellite beacon signal. The fallback mode ingress/egress mechanism requests the satellite terminal to switch out of the fallback mode in response to a second value of the satellite beacon signal parameter.Type: GrantFiled: November 10, 2003Date of Patent: June 10, 2008Assignee: Hughes Network Systems, LLCInventors: Jerry Dai, Anwer Khan, Stan Kay, Yezdi Antia
