  • Patent number: 11356169
    Abstract: Techniques, systems, devices, and methods for utilizing a mobile communicator for communicating with multiple satellites, e.g., simultaneously over an interval of time, are disclosed. The mobile communicator is disposed on a vehicle, and the multiple satellites may be disposed in different satellite constellations operating in different orbits. The mobile communicator establishes multiple communication links to the multiple satellites by utilizing only the set of antenna resources provided by a single antenna platform or array. Subsets of the antenna resources are dynamically apportioned and adapted, e.g., while the vehicle travels, to establish and maintain different communication links to different satellites via different spatial channels and their respective air interfaces to thereby maintain optimal satellite communicative connectivity. On-board connectivity services for personal electronic devices and/or other on-board applications may be supported by the disclosed techniques.

  • Patent number: 11336364
    Abstract: Satellites provide communication between devices such as user terminals and gateways to other networks, such as the Internet. Non-geosynchronous orbit satellites move relative to terrestrial user terminals, passing in and out of communication over time. To maintain ongoing communication, a handover takes place in which the responsibility to maintain communication with a particular user terminal passes from one satellite to another. To minimize disruption due to the handover, satellite motion and availability of communication resources are allocated in advance. Participating devices such as the user terminal, current satellite, and next satellite, are provided with details of the handover in advance. As a result, interruption in communication due to a handover from one satellite to another is substantially reduced.

  • Patent number: 10958334
    Abstract: A Non-Geostationary Satellite Orbit (NGSO) satellite system is described that implements one or more user route tables and a plurality of pre-calculated backbone route tables at its satellites. The user route tables track user connectivity to the satellites, and each of the backbone route tables defines a snapshot of a time-varying backbone topology seen by a particular satellite. During operation, a satellite selects different backbone route tables as the topology changes over time, and receives updates to the user route tables when connectivity changes occur between the users and the satellites. The decoupling of the user route tables from the backbone route tables at the satellite reduces the computational burden on the NGSO system, as the backbone route tables are calculated in advance and the NGSO system is subsequently tasked with a computationally lower burden of performing real-time updates to the user route tables.

Based on a seat mapping stored within a server, a seat display unit and its allocated peripherals can be paired in sequence, one-by-one. Thus, a first seat display unit and its allocated peripherals can be powered on. Then, the peripherals can be paired with the first seat display unit, and the first seat display unit and the allocated peripherals can be powered down. Once this is complete, the next seat display unit and its allocated peripherals can be powered on, paired, and then powered down before continuing in sequence until all peripherals are paired with their allocated seat display units.

  • Patent number: 10601498
    Abstract: An embodiment of the present invention is a system to maximize efficiency as a mobile terminal receives data signals transmitted through multiple satellite spot beams. The multiple spot beams can be broadcast via a single satellite or multiple satellites. As a mobile terminal travels throughout a region, the system determines which spot beam would delivers data in the most efficient manner possible. This system takes into account multiple factors, including but not limited to velocity of the mobile terminal, traffic within a spot beam, business affiliations, etc. Once the system takes into account the various factors, an embodiment of the present invention generates a relative weighted factor that is subsequently associated with various available spot beams. Based on rankings of the weighted factors associated with each spot beam, the system may choose to receive data from a different spot beam.

  • Patent number: 10567072
    Abstract: The present invention relates to satellite systems and more particularly, to the provision of novel systems and methods for verifying the in-orbit performance and operation of satellite communications subsystems. In contrast to traditional Payload IOT (in-orbit test), the invention operates without an uplink signal, by generating hardware-specific signatures using isolated, internally generated, thermal noise. It has been found that this noise provides a very stable, repeatable signal for testing. Prior to launch, a repeater command sequence is executed to generate a hardware-specific signature based on the internally-generated noise. The same repealer command sequence is then executed in-orbit to determine whether the hardware-specific signature has changed. The two signatures may be recorded and compared using a simple tool such as a spectrum analyzer.

  • Patent number: 10512018
    Abstract: Approaches for efficient, dynamic and continuous handover processes, which encompass selection of an optimal path (consisting of a satellite, a satellite beam and carrier frequency set) over which a mobile user terminal (UT) communicates with the radio access network in a mobile satellite communications system, are provided. A set of path factors are determined regarding each of a plurality of communications paths for the UT. A path selection metric (PSM) for each communications path is determined, wherein the PSM for each communications path is determined via a weighted calculation based on the respective set of path factors for the communications path. A decision is made as to whether to perform a handover of the UT from a first of the communications paths to a second of the communications paths, wherein the determination is based on an evaluation performed based at least in part on the PSM.
