  • Patent number: 10812177
    Abstract: Systems and methods are described herein for adaptive pointing operations of a mobile antenna system that can be used to provide communication with a target satellite over a large geographical area, while also satisfying interference requirements with one or more other satellites. In particular, the adaptive pointing operations described herein control pointing of a beam of the antenna system towards the target satellite in a manner that takes into consideration the interference requirements of the other satellites. In some embodiments, the mobile antenna system can provide non-interfering communication with the target satellite, over the entire or substantially the entire coverage area (or footprint) of the target satellite. In doing so, services such as Internet, telephone and/or television services provided by the target satellite can be delivered to users throughout most or all of the satellite's coverage area, while also satisfying interference requirements with other satellites.

  • Patent number: 10784954
    Abstract: Embodiments provide techniques for dynamic spot beam assignment in a geostationary satellite communications network. For example, a ground processing node in the geostationary satellite network can monitor spot beam coverage area location and can detect a beam drift trigger indicating present drifting of one or more coverage areas. Ground terminals can be identified as serviced by spot beams associated with the drifting coverage area(s) and as experiencing a signal quality impact from the drifting. The ground terminal node can compute an update to a beam assignment map having a reassignment of the identified user terminals from their presently servicing spot beams to another of the spot beams in a manner that seeks to address at least some of the signal quality impact identified as associated with the drifting. Some embodiments further account for load balancing, and/or other factors, and/or can maintain stateful communications between the reassigned user terminals and the geostationary satellite.

  • Patent number: 10757663
    Abstract: A communication device, method, and computer program product provide communication quality mitigation in response to an intermodulation product resulting from concurrent transmission by first and second transmitters of a communication device. A controller is communicatively coupled to the first and second transmitters and executes an intermodulation mitigation utility that enables the communication device to monitor transmission characteristics of first and second transmitters of the communication device. The controller determines whether concurrent transmissions by the first and second transmitters create an intermodulation product having a power level at one or more frequencies that exceeds an intermodulation threshold for at least one of: (i) spurious emissions to a thirty-party receiver; and (ii) desensing a receiver of the communication device.
