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.

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.

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.

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.

Systems and method are provided to facilitate predictive mitigation of noise. A vehicle may measure noise floor levels and transmit a noise floor signal to a noise signal aggregator. Based on the noise signal, the noise signal aggregator may update a noise floor map database. The noise floor map database may associate a plurality of geographic locations with a plurality of noise floor levels. Accordingly, the noise signal aggregator may update a noise floor level in the noise floor map database that corresponds to the location associated with the transmitted noise signal. The noise floor map database may then be queried to retrieve noise floor levels for locations further along a route traversed by a vehicle such that the vehicle may predictively tune one or more antennas to mitigate interference associated with the noise floor.
