摘要： A method of communicating with multiple satellites includes allocating, based on one or more conditions corresponding to a plurality of spatial channels associated with multiple satellites, each subset of a plurality of subsets of antenna resources of a phased array antenna to a respective different satellite included in the multiple satellites. The method also includes commanding one or more transceivers to establish simultaneous communicative connections to the different satellites via the allocated subsets of antenna resources, and re-allocating, based on a detected change to at least one of the one or more conditions, at least one antenna resource to a respective another different satellite. The method also includes commanding the one or more transceivers to maintain the simultaneous communicative connections to the different satellites using the re-allocated at least one antenna resource.

摘要： A vehicle communication system includes a controller configured to be communicatively coupled to one or more antennas. The controller is also configured to adjust a beam during a period of time to be oriented at a plurality of pointing angles, and detect a plurality of sets of signal data for a received signal, where each set of signal data is detected at a different one of the pointing angles. The controller is further configured to identify a particular pointing angle based on the plurality of sets of signal data, reorient another beam from the given pointing angle to the particular pointing angle, and transmit or receive data, via the other beam while the other beam is oriented at the particular pointing angle, between a particular external node and at least one internal node.

摘要： 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.

摘要： A first beam is implemented, from a set of vehicle-based antennas, for current or future communication with a ground-based or satellite-based network via an external antenna (e.g., of a base station or satellite). A second beam may be implemented to detect or determine a better pointing angle for the first beam, thereby “fine tuning” the pointing angle for the first beam. Specifically, the second beam may be “swept” through a range of pointing angles while a signal parameter representing signal quality or strength is measured, detected, or calculated at each pointing angle. The values for the signal parameter may be evaluated to identify a desired value and the pointing angle at which the desired value was obtained. The first beam may be reoriented or repointed at the desired pointing angle, and one or more nodes of vehicle-based communication system may communicate with an external network via the first beam.

摘要： Novel techniques for pooling the available transmit power of a beam across the subcarriers that are or that are scheduled to be in use (and not across all available subcarriers) are disclosed. The scheduled subcarriers may be located in the same or different carriers of a modulation transmitter modulation system, and the pooled transmit power may be allocated or distributed across the scheduled subcarriers of the beam. Modulation symbols or resource elements may be transmitted in accordance with allocated, per-subcarrier power budgets, thereby maximizing the SNIR of signals that are transmitted in the beam via the scheduled subcarriers. Additionally, the allocation of the pooled transmit power to various subcarriers may continuously and/or dynamically vary over time, e.g., based on traffic demands, interference characteristics, etc., as well as based on subsequent scheduling of subcarriers to transmit subsequent modulation symbols or resource elements.
