  • Publication number: 20240250899
    Abstract: A satellite communication system with software defined network orchestration which provides differentiated quality of service (QoS). Implementations include a route manager (RM) that receives link status from the satellites and determines routing tables with QoS attributes which are uploaded to the satellites. The routing tables and the QoS attributes allow the satellites to route data based on a QoS attributes in a data header to achieve differentiated QoS for data routed in the network. The QoS attributes may also be used to prioritize data through a satellite node.

  • Patent number: 12021602
    Abstract: A satellite communication system with software defined network orchestration. Implementations include a route management function (RMF) that receives link status from the satellites and determines simple routing tables which are uploaded to the satellites. The routing tables allow the satellites to route data based on a satellite ID placed in a data header to reduce the memory and computing load on satellite resources. Further, implementations include secure user terminal (UT) to UT IP routing in the constellation for direct UT to UT communication. The satellite communication system may combine the benefits of Medium Earth Orbit (MEO) and Low Earth Orbit (LEO) satellite systems into an MEO-LEO satellite system.

  • Patent number: 11916654
    Abstract: A satellite communication system that combines the benefits of Medium Earth Orbit (MEO) and Low Earth Orbit (LEO) satellite systems into an MEO-LEO satellite system. The MEO-LEO system includes an LEO constellation combined with a MEO constellation where the LEO constellation may provide global coverage with broad average capacity and may support ‘hot spot’ coverage where desired. The MEO constellation may provide unique advantages including backhaul to ground in remote areas, higher traffic density for key locations, and a secure global backhaul for key customers. Data may be routed over optical inter-satellite links using Software Defined Networking concepts to provide MEO-LEO (backhaul and ground access), LEO-LEO (upstream & downstream); and (3) MEO-MEO (crosslinks & downlinks). Further, implementations described herein include secure user terminal (UT) to UT IP routing in the constellation for direct UT to UT communication.

  • Publication number: 20240031949
    Abstract: An adaptive transmit power control process enables the uplink transmit power of a user terminal to be adjusted based on a scan angle of the antenna for the user terminal. The antenna periodically reports the scan angle to the user terminal, and a current maximum transmit power for the user terminal is determined based on the scan angle. The current maximum transmit power is then used as the basis for determining an allocation of resources to the user terminal. The transmit power control process enables resources to be assigned as needed across multiple carriers and enables a power spectral density of a user terminal to be adjusted based on nominal and offset transmit power parameters.

  • Patent number: 11777618
    Abstract: Techniques described herein provide phase and amplitude calibration of phased array antennas. In an N-by-M phased array having N*M channels, embodiments use aggregated measurements over multiple concurrently active channels to improve signal-to-leakage performance, while also using sequences of exclusion groups to yield an individualized calibration value for each channel (i.e., N*M individualized calibration values). For example, a J×K channel group of the array is selected in each of a sequence of measurement frames based on a calibration schema. Over J*K measurement sub-frames, a set of J*K aggregate measurements is obtained, each with different subsets of the channel group activated and excluded from the measurement. The aggregate calibration measurements can be used to compute J*K individualized calibration values, each for a channel of the channel group. In some implementations, each calibration value is computed as a complex value including both amplitude and phase calibrations information.

  • Publication number: 20230075345
    Abstract: A satellite communication system which provides interference mitigation across multiple constellations. The satellite communication system provides interference mitigation when an in-line event occurs where a main lobe of a satellite of the first constellation and a main lobe of a user terminal communicating with the satellite of the second satellite constellation intersect sufficiently to cause significant interference on a common frequency band of the satellite and the user terminal.
