Publication number: 20230006754Abstract: Systems and methods for calibrating a phase array antenna (“PAA”) are provided. The system includes a PAA having a plurality of array elements and a remote calibration terminal. The PAA is connected to a processor unit. The PAA includes a reference beamforming network (“BFN”) for generating a reference beam and a calibration BFN for generating a calibration beam. The PAA applies a plurality of scrambled orthogonal codes to the calibration BFN to generate the calibration beam. The remote calibration terminal is configured to analyze the reference beam and the calibration beam to determine a calibration error for the PAA, the calibration error including a phase error and an amplitude error for each of the plurality of array elements of the PAA. The remote calibration terminal may be configured to measure a beam pointing error (“BPE”) of the PAA and/or a coupling between array elements.Type: ApplicationFiled: December 10, 2020Publication date: January 5, 2023Inventors: Michel Bellemare, Saeed Daneshmand, Guillaume Lamontagne

Patent number: 10797784Abstract: A satellite system that includes a gateway, a satellite, and a user terminal. The gateway determines a modulation scheme based on a function of uplink and downlink signal quality and a defined relationship between the downlink modulation to the uplink modulation. The satellite includes an input demodulator configured to apply an input modulation and coding (modcod) scheme; an output modulator configured to apply an output modcod scheme; and an output modcod scheme selector configured to select an output modcod scheme for the output modulator based on the input modcod scheme according a predetermined relationship between input modcod schemes and output modcod schemes. The user terminal providing the gateway a measure of downlink signal quality.Type: GrantFiled: October 31, 2017Date of Patent: October 6, 2020Assignee: Space Systems/Loral, LLCInventors: William Hreha, Edmond Ahad, Guillaume Lamontagne

Patent number: 10135154Abstract: A satellite communication system comprises a satellite configured to provide a plurality of spot beams adapted for communication using time domain beam hopping to switch throughput among spot beams of the plurality of spot beams. The plurality of spot beams includes a first spot beam that illuminates and communicates with a first gateway and a first set of subscriber terminals. The satellite is configured to implement a beam hopping plan that during a hopping period provides throughput to the first spot beam for an aggregated time duration based on bandwidth assignments to the first gateway and the first set of subscriber terminals.Type: GrantFiled: June 3, 2016Date of Patent: November 20, 2018Assignee: Space Systems/Loral, LLCInventors: William Hreha, Erin Michelle Lavis, Guillaume Lamontagne

Patent number: 10128577Abstract: A non-geostationary satellite is configured to provide a plurality of spot beams that implement a first frequency plan at Earth's Equator and a second frequency plan away from Earth's Equator. The second frequency plan is different than the first frequency plan. In one embodiment, the non-geostationary satellite is part of a constellation of non-geostationary satellites, with each of the satellites providing spot beams that implement a first frequency plan at Earth's Equator and implement a second frequency plan away from Earth's Equator as the satellites travel in orbit around Earth.Type: GrantFiled: June 3, 2016Date of Patent: November 13, 2018Assignee: Space Systems/Loral, LLCInventors: William Hreha, Guillaume Lamontagne, Eric Shima

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
