  • 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: 10158431
    Abstract: A method for mitigating the effect of a localized jamming attack on a secure, tactical wireless network implements a dynamic relay assignment (“DRA”) approach, whereby nodes are dynamically assigned to relay communications to “disadvantaged” nodes that are subject to the attack, the relay nodes being selected based on their communication reliability and their proximity to the disadvantaged nodes. In embodiments, the nodes share with each other performance statistics and, in embodiments, measured local noise levels. In various embodiments, each node provides data to a “strategy optimizer” which then dynamically makes relay assignments. In Link-16 embodiments support for a “DRA” relay mode is added, and the communication protocol is extended to support the required exchange of communication quality and local noise information via PPLI messages.

    Abstract: A system and related method for minimizing co-channel interference in air-to-ground single-frequency networking includes aircraft-based directional and omnidirectional antenna arrays for transmitting to single frequency networks (SFN) (e.g., LTE, HSPA) and their cell sites. The directional array may encompass several cell sites to take advantage of C-RAN architectures. 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: 9801183
    Abstract: A mobile communications system including: at least one base station configured to communicate data to/from different terminal devices via respective of plural logically separate carriers of a wireless access interface; first and second terminal devices operable to camp-on to first and second carriers of plural carriers and to subsequently communicate data with the at least one base station via the first and second carriers. The first and second carriers support compatible synchronization signaling such that the first and second terminal devices both can synchronize with the first and second carriers to begin a camp-on procedure. Following synchronization with one of the first or second carriers to begin the camp-on procedure, the second terminal device is configured to determine whether or not to continue with the camp-on procedure in dependence on an aspect of physical layer signaling associated with a control channel of the carrier with which it has synchronized.

  • Patent number: 9693184
    Abstract: Techniques for supporting a control plane solution for location services and positioning are described. In an aspect, an Evolved Serving Mobile Location Center (E-SMLC) may communicate with a Mobility Management Entity (MME) to support location services and positioning for a UE. In one design, the E-SMLC may receive a location request from the MME, perform a positioning procedure with the UE in response to the location request, and send a location response to the MME after completing the positioning procedure. For a UE-assisted or UE-based positioning procedure, the E-SMLC may send a downlink positioning message to the UE via the MME and may receive an uplink positioning message from the UE via the MME. For a network-based positioning procedure, the E-SMLC may send a network positioning request message to an eNB via the MME and may receive a network positioning response message from the eNB via the MME.

  • Patent number: 9681413
    Abstract: A system for tracking mobile subscribers, the system includes an aircraft having an on-board virtual BTS that substitutes for a stationary BTS. The virtual BTS emulates a behavior of the stationary BTS so as to be indistinguishable from the stationary BTS to the mobile device, including emulation of communication protocols and billing operations The virtual BTS communicate with the mobile devices. The virtual BTS includes a processor running Software Defined Radio (SDR) and a signal amplifier, the SDR receiving identifiers of the mobile devices. The aircraft includes a high-gain antenna for determining directions of signals from the mobile devices. A camera on board the aircraft takes images or video of an area on the ground. The processor collects and processes the images or video, the directions of the signals and the identifiers of the mobile devices to locate a specific subscriber. The processor transmits the processed information to a server.

  • Patent number: 9617018
    Abstract: The process validates measurement data that are consistent with the current orbit or allowable maneuvers for Earth-orbiting satellites. The validated data may be processed to detect both large and small maneuvers; large maneuvers that may have been rejected by standard data validation process and small maneuvers that may have been missed. Large maneuvers may present as “trends” in the residuals above the noise threshold from multiple sensors. Small maneuvers may present as a deviation from the expected orbit. The OD engine is suitably configured (as per normal operation) to enforce data reduction on any outliers (e.g. >3 sigma). The maneuver estimation routines employ an objective function for selection of maneuver estimates that combines a residual fit to the current orbit and maneuver, orbit consistency and a penalty for validated but unused data (data that is rejected by the OD engine).
