  • Patent number: 11316656
    Abstract: A time transfer modem includes a radio frequency integrated circuit (RFIC), a radio frequency (RF) front end, and processing circuitry. The RF front end is configured to receive and up-convert an input for time transfer with a remote station to generate an up-converted timing signal centered at a select frequency that is outside of a frequency range of interest but within an operational frequency range of the RFIC. The RF front end may also be configured to attenuate, via a pre-selection filter, up-converted adjacent signals to generate a filtered timing signal at the select frequency. The RFIC may be configured to down-convert and digitize the filtered timing signal to generate a digitized timing signal for signal processing by the processing circuitry to determine a clock difference between a local clock signal and the digitized timing signal that originated from the remote station.

  • Patent number: 11032751
    Abstract: A method for prediction of UT handovers in a satellite communications network is provided. Optimal characteristics regarding the beams of satellites and regarding a one UT are determined. For each of a plurality of the satellite beams, for each of a plurality of instants of time tn, an estimated signal strength as seen at the UT is determined, wherein each estimated signal strength is determined based on the optimal at the respective time tn. A next instant of time tm is determined at which the estimated signal strength for a candidate beam that is within the view of the UT is greater than or equal to the estimated signal strength for the satellite beam that is currently servicing the UT. A handover of the UT, at the time tm, from the satellite beam that is currently servicing the one UT to the candidate beam is determined.

  • Patent number: 11011839
    Abstract: A method for orienting reflectors of a communications system in a zone, wherein the communications system includes an antenna and the reflectors. The antenna is operable in one or more frequencies in a frequency range from 0.1 THz to 10.0 THz, with each of the reflectors being spaced apart from each other and the antenna. The method includes the steps of digitally predicting a future motor vehicle density distribution in the zone based on obtained past motor vehicle density distributions in the zone; digitally computing an orientation of each reflector such that the estimated power reception of electromagnetic waves radiated by the antenna is globally maximized for each motor vehicle of the future motor vehicle density distribution; and orienting each reflector according to the digitally computed orientation.

  • Patent number: 10924179
    Abstract: 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.

  • Patent number: 10917796
    Abstract: A satellite system has satellites supporting inter-satellite communication to form a multihop communication network; computing servers distributed over the satellites and networked together to form a space-based Internet network; and Border Gateway Protocol (BGP) routers integrated to the space-based Internet network. Each satellite is installed with a BGP router to locally manage the servers installed in this satellite. Data packets generated by the servers are transmitted from the servers to the BGP router entirely over an in-satellite local area network for carrying out routing of the data packets, lessening a communication burden on inter-satellite communication. The BGP routers also assign autonomous system (AS) numbers to the servers so as to enable the space-based Internet network to function independently without a need for support from a terrestrial Internet network.

  • Patent number: 10887779
    Abstract: This spectrum protection system enables spectrum sharing that protects Earth Exploration-Satellite Services (EESS) observations, which allows for uninterrupted weather forecasting, from terrestrial operations that operate near or within EESS frequency bands without cumbersome restrictions on telecommunications (telecom) providers. The system calculates the satellite observation times using a device's location recognizing that these satellites are only observing a particular location on Earth for a very small amount of time because of their orbital dynamics and scanning characteristics. Using this calculated list of observation times and comparing it to the current time input, the system then enacts a mechanism for action when EESS observations are occurring. Two simple embodiments for the mechanism for action include momentarily changing frequencies or reducing transmission power levels to prevent erroneous EESS measurements.

  • Patent number: 10880791
    Abstract: A method and system for performing handover in a third generation (3G) long term evolution (LTE) system are disclosed. A source evolved Node-B (eNode-B) makes a handover decision based on measurements and sends a handover request to a target eNode-B. The target eNode-B sends a handover response to the source eNode-B indicating that a handover should commence. The source eNode-B then sends a handover command to a wireless transmit/receive unit (WTRU). The handover command includes at least one of reconfiguration information, information regarding timing adjustment, relative timing difference between the source eNode-B and the target eNode-B, information regarding an initial scheduling procedure at the target eNode-B, and measurement information for the target eNode-B. The WTRU then accesses the target eNode-B and exchanges layer 1/2 signaling to perform downlink synchronization, timing adjustment, and uplink and downlink resource assignment based on information included in the handover command.
