  • 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.

  • 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.

The system may default to the directional array to establish or re-establish network access, identifying accessible networks and sites and monitoring corresponding synchronization cell counts. The system may minimize co-channel interference with terrestrial network users by switching to the directional array if the count of accessible cell sites or networks becomes high enough, or due to additional factors (e.g., climbing above a threshold altitude). Similarly, the system may switch to the omnidirectional array if the cell count drops below a threshold level.

  • Patent number: 9917635
    Abstract: Signals of data streams for transmission to user equipment (UE) in spoke-and-hub configurations will utilize multiple transponders of satellites. Radiation patterns from ground terminals with distributed apertures feature orthogonal beams (OB). A tracking OB beam from a moving platform dynamically shall autonomously be formed as a shaped beam by a digital-beam-forming (DBF) network with a peak to a desired satellite, and nulls to undesired satellites to minimize mutual interferences among multiple satellite spatially. Ground hubs and mobile terminals feature “coherent” bandwidth aggregating capability from multiple available but non-contiguous slices of frequency slots in many transponders by wavefront multiplexing/demultiplexing (WF muxing/demuxing) techniques. These individual frequency slots must be dynamically selected, calibrated and equalized continuously in receivers via embedded probing signals as a part of WF muxing/demuxing techniques.

  • Patent number: 9912526
    Abstract: Aspects of the subject disclosure may include, for example, determining a first tuning state of a media processor of a subscriber. The first tuning state includes a satellite service channel of a number of channels, wherein the satellite service channel provides a first media content item that is processed by the media processor for presentation. A terrestrial service channel is identified that provides a second media content item. The terrestrial service channel is accessed, but not at a time of access processed by the media processing device for presentation. An unavailability is determined of the satellite service channel to the media processor, and subsequent processing of the second media content item by the media processor is facilitated by replacing the first media content item, responsive to the determining of the unavailability of the satellite service channel. Other embodiments are disclosed.

  • Patent number: 9894687
    Abstract: Methods and devices are provided. Devices asynchronously transmit, without diversity, bursts including information encoded using a low rate FEC code having a code rate no higher than ½. A terminal receives transmitted multiple overlapping bursts. The terminal detects and decodes bursts in a window of burst times, performs an iteration of an iterative interference cancellation process, and when at least one burst of at least a portion of the window remains incorrectly decoded, another iteration of the iterative cancellation process is performed as long as a maximum number of repeated iterations has not yet been performed. When all of the bursts in at least the portion of the window are correctly decoded, the window is advanced by an amount of burst time, at least the portion of the window is updated, and the iterations may be repeated. Correctly decoded bursts may be passed to a next process or device.

  • Patent number: 9820172
    Abstract: Certain features relate to systems and methods for jointly optimizing a radio access network (RAN) and distributed antenna system (DAS). A joint RAN-DAS self-optimizing network (SON) entity can determine target parameters based on parameters specific to the DAS and parameters specific to the RAN. The joint RAN-DAS-SON entity can optimize the RAN and DAS using the target parameters. Jointly optimizing the RAN and the DAS can improve the capacity characteristics, coverage characteristics, or the performance characteristics of the RAN and DAS. In some aspects, the joint RAN-DAS-SON entity can optimize the RAN and DAS by re-allocating power levels of downlink signals transmitted by remote units of the DAS to compensate for underutilized carrier signals in situations of low traffic load.
