  • Patent number: 10826597
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for adjusting the transmission power of satellite transceivers based on estimated interference. In some implementations, a satellite transceiver receives a data structure that specifies an interference compensation value for at least one frequency channel on which the satellite transceiver can transmit. The interference compensation value for the frequency channel is based on estimated interference imposed on satellite transmissions transmitted by the transceiver on the frequency channel. The transceiver receives data specifying a second transmit frequency channel to use for a second satellite transmission. A first interference compensation value for a first frequency channel and a second interference compensation value for the second frequency channel are identified from the data structure.

  • Patent number: 10771147
    Abstract: A satellite communication system includes a communication terminal, and a ground station. The ground station is configured to communicate with the communication terminal through a satellite communication path between the ground station and the communication terminal via a satellite. The ground station includes a diversity switch, and an electronic controller. The diversity switch is configured to switch the satellite communication path from a first satellite communication path to a second satellite communication path different from the first satellite communication path. The electronic controller is configured to determine whether a predetermined switching condition is satisfied based on signal attenuations of the first and second satellite communication paths. The electronic controller is further configured to control the diversity switch to switch the satellite communication path upon elapsing a first predetermined time period after determining that the predetermined switching condition is satisfied.

  • Patent number: 9941952
    Abstract: A satellite terminal and a machine-implemented method are provided for encoding a burst header of a burst for transmission on an inroute. One component of a group of satellite terminal components consisting of an ASIC, a FPGA, and a DSP, generates a burst header having five information bits encoded therein. The five information bits may be encoded using a Reed-Muller code, a (32, 5) block code or a convolutional code having a code rate of either 1/5 or 1/10. The five information bits may represent one or more of a modulation type for a payload of the burst, a code rate for encoding the payload, a code type, and a spreading factor for spreading the payload during transmission. A satellite gateway and a machine-implemented method are also provided for decoding a burst header of a burst received on an inroute as described above.

  • Patent number: 9871578
    Abstract: An uplink power control system and a machine-implemented method for determining clear sky and adjusting uplink power are provided. A receiving station, which may be a satellite terminal or a satellite gateway, receives a reference signal from a satellite. The reference signal may be sampled over a sampling time period in order to compute a filtered short-term average downlink SINR. A filtered long-term average downlink SINR may be adjusted toward the filtered short-term average downlink SINR using either a first time constant or second time constant, based on a relationship between the filtered long-term average downlink SINR and the filtered short-term average downlink SINR. In some implementations, the second time constant is less than the first time constant.

  • Patent number: 9854544
    Abstract: Power spectral density in an aeronautical satellite communication system is controlled through the use of adaptive inroute selection and spreading. Once a communication session has been established between the aircraft and the satellite, environmental conditions and aircraft conditions are monitored to detect events capable of affecting transmit/receive properties during the communication session. A maximum allowable transmission output is determined based, at least in part, on governmental regulations and the conditions being monitored. One or more transmit parameters are adjusted during the time interval in order to maintain transmission output power of the aircraft terminal below the maximum allowable transmission output power.

  • Patent number: 9813147
    Abstract: Systems and methods are provided for automatically re-ranging a satellite terminal. A satellite system may comprise a satellite comprising an inroute channel and an outroute channel, and a terminal configured to receive an outroute signal from the satellite on the outroute channel and transmit an inroute signal to the satellite on the inroute channel. The satellite terminal may automatically determine when to perform ranging by monitoring the quality of the outroute signal; monitoring the quality of the inroute signal; and determining if there has been a sustained degradation in the monitored inroute signal quality or the monitored outroute signal quality.
