Patent number: 8594661Abstract: A method for establishing radiofrequency links via a telecommunication satellite having several spots, designated a multispot satellite, between at least one terrestrial station and a service area composed of a plurality of elementary covering zones, designated cells, each cell comprising a plurality of terrestrial terminals is disclosed. This type of satellite allows the use of several spots of antennae on board the satellite to cover contiguous geographical zones or cells, instead of a single broad spot. Each cell is associated with a spot to which a frequency band is attributed. In the case of the loss of a spot associated with a cell, designated a faulty cell, the spot (FR1, FR2, FB1, FB2, FV1, FV2) associated with at least one contiguous cell (CR1, CR2, CB1, CB2, CV1, CV2) to the said faulty cell is likewise associated with a part of the said faulty cell so that the area (CPJ?) of said faulty cell is reduced.Type: GrantFiled: April 16, 2008Date of Patent: November 26, 2013Assignee: Eutelsat SAInventors: Hector Fenech, Emmanuel Lance, Jacques Dutronc

Patent number: 8554203Abstract: A satellite signal demodulator is configured to use frequency-based channel scanning to sense the presence of a channel and to obtain the frequency profile of the channel. Once the channel is identified and the profile is obtained, channel extraction is used to identify the frequency parameters for a given channel. A coarse parameter estimation is performed to obtain a coarse estimate of the symbol rate (SR) and the center frequency (fc) of the channel. The coarse estimation can then be followed by a fine estimation of the symbol rate and center frequency (fc), using a bit tracking loop (BTL) lock indicator.Type: GrantFiled: September 7, 2012Date of Patent: October 8, 2013Assignee: Conexant Systems, Inc.Inventors: Prasad Shamain, Chi-ping Nee, Gadi Kalit

Patent number: 8538328Abstract: Disclosed is a satellite beam pointing system that uses color encoded signals from subscribers to align antennas on a satellite and to align the satellite. Subscribers detect the signal strength and signal-to-noise ratio of signals that are transmitted from the satellite. The values of the signal strength and signal-to-noise ratio data are encoded in signals that are transmitted back to a ground station that color encodes the data and graphically displays the signal strength and signal-to-noise ratio of the subscriber received signals. The actual beam projection can then be determined and the satellite antennas moved, so that the actual beam projection coincides with the intended beam projection. Also, the satellite can be properly oriented using this technique.Type: GrantFiled: August 19, 2009Date of Patent: September 17, 2013Assignee: ViaSat, Inc.Inventors: Raymond L. Mills, Remberto L.

Patent number: 8526941Abstract: Communications between a terminal and a terrestrial base station are established. The terrestrial base station receives a request to monitor a satellite base station from the terminal. The terrestrial base station grants the request and receives monitoring information for the satellite base station corresponding to the request. Granting of the request may include suspending transmission from the terrestrial base station to the terminal for a period of time sufficient to allow the terminal to request the monitoring information from the satellite base station and receiving monitoring information may include receiving the requested monitoring information at the terrestrial base station via a communications path not including the terminal. Suspending transmission from the terrestrial base station to the terminal may be followed by resuming transmission to the terminal before receiving the monitoring information at the terrestrial base station.Type: GrantFiled: June 28, 2007Date of Patent: September 3, 2013Assignee: ATC Technologies, LLCInventors: Michael Tseytlin, Santanu Dutta
