Patent number: 10418724Abstract: A satellite communication system includes a non-geostationary satellite configured to provide a first plurality of non-articulated spot beams that comprise a Field of Regard. The satellite further configured to provide a steerable spot beam that can be steered to establish communication with a gateway outside and in front of the Field of Regard and maintain communication while the satellite and the Field of Regard moves over and past the gateway including after the gateway is outside of and behind the Field of Regard.Type: GrantFiled: June 3, 2016Date of Patent: September 17, 2019Assignee: Space Systems/Loral, LLCInventors: William Hreha, Anne Elizabeth Wharton

Patent number: 10411362Abstract: Synchronization technology is implemented for a satellite communication system. Master clock information is accessed at a terrestrial location. A timing message based on the master clock information is transmitted from the terrestrial location to a satellite as the satellite is in orbit. The satellite is synchronized to the master clock based on the timing message. A beacon signal is transmitted from the satellite toward Earth. The beacon signal includes timing information. The beacon signal is received at a ground based gateway. The gateway is synchronized to the satellite based on the beacon signal. Communication is sent from the gateway to a terminal via the satellite. The communication includes timing data. The terminal is synchronized to the gateway based on the timing data.Type: GrantFiled: June 3, 2016Date of Patent: September 10, 2019Assignee: Space Systems/Loral, LLCInventors: William Hreha, Anne Elizabeth Wharton, David Linford Foulke, Richard Wallace Voreck, Shervin Shambayati

Patent number: 10381748Abstract: A satellite communication system provides for handovers between satellites and multiple gateways. Terminals communicate with a first gateway via a first satellite as beams of the first satellite traverse the region. A second gateway is in communication with the first satellite and hands over to a second satellite. The first gateway is at a first location. The second gateway is at a second location separated from the first location in the orbital direction. Terminals handover to the second satellite as beams of the second satellite begin to traverse the region, and the terminals start connecting to and communicating with the second gateway via the second satellite. After all of the terminals of the plurality of terminals handover to the second satellite, the first gateway hands over to the second satellite and then the terminals in the region communicate with the first gateway via the second satellite.Type: GrantFiled: June 3, 2016Date of Patent: August 13, 2019Assignee: Space Systems/Loral, LLCInventors: William Hreha, Anne Elizabeth Wharton

Patent number: 10347987Abstract: A satellite communication system includes a satellite configured to provide a first plurality of spot beams adapted for communication with subscriber terminals using time domain beam hopping and a second plurality of spot beams adapted for communication with gateways. The satellite includes a spectrum routing network that is configured to time multiplex spot beams of the second plurality of spot beams with spot beams of the first plurality of spot beams so that a spot beam that is implementing beam hopping for communication to subscriber terminals communicates with different feeder beams (and, therefore, different gateways) at different times during a hopping period.Type: GrantFiled: June 3, 2016Date of Patent: July 9, 2019Assignee: Space Systems/Loral, LLCInventors: William Hreha, Anne Elizabeth Wharton, David Linford Foulke

Patent number: 10128578Abstract: A satellite communications system provides for handovers between spot beams, including communicating (at a ground based terminal) with a non-geostationary satellite constellation using a first spot beam of the non-geostationary satellite constellation and a first beam hopping plan. The ground based terminal changes the communicating with the non-geostationary satellite constellation to use a second spot beam of the non-geostationary satellite constellation and a second beam hopping plan.Type: GrantFiled: June 3, 2016Date of Patent: November 13, 2018Assignee: Space Systems/Loral, LLCInventors: William Hreha, Anne Elizabeth Wharton

Patent number: 10111109Abstract: A satellite communication system comprises one or more non-geostationary satellites. Each satellite is configured to provide a plurality of spot beams using time domain beam hopping among the spot beams. The spot beams are divided into hopping groups and each satellite is configured to switch throughput and power among spot beams in a same hopping group at intervals of an epoch over a hopping period according to a hopping plan. Each satellite is configured to receive, change and implement the hopping plan in orbit while the satellite moves in relation to a fixed geographic coverage region. The satellites are programmable to assign any combination of epochs in a hopping plan among spot beams of a same hopping group and to route throughput between spot beams.Type: GrantFiled: June 3, 2016Date of Patent: October 23, 2018Assignee: Space Systems/Loral, LLCInventors: William Hreha, Anne Elizabeth Wharton, Erin Michelle Lavis, David Linford Foulke, Guillaume Lamontagne, Eric Shima, Louis Trichardt Hildebrand
