The DGSS mechanisms may include mechanisms for determining an instantaneous field of view (IFOV) and mechanisms for modifying transmission characteristics while network antennas and power radiated by such antennas are within a window encompassing the IFOV. For example, when the IFOV of a satellite sensor for measuring atmospheric water includes a 5G antenna, the power of the 5G antenna may be reduced, the 5G antenna may be prevented from utilizing a segment of the electromagnetic spectrum, etc.Type: GrantFiled: August 12, 2020Date of Patent: August 17, 2021Inventor: Elliot Eichen

Patent number: 11043736Abstract: An antenna beam tracking system has dynamic interference reduction. The system includes antennas that can form multiple beams, each beam of which can continually track or point its beams independently in various angular directions. A first beam continually tracks and receives (downlink) signals from a desired source or node such as a satellite or terrestrial node which generally has an apparent motion relative to the antenna. A second beam continually tracks and receives potentially harmful interference signals that may arise from different directions. The signals of the second beam are dynamically coupled to the signals in the first beam in such a manner as to effect cancellation or substantial reduction of the interference.Type: GrantFiled: September 18, 2020Date of Patent: June 22, 2021Assignee: Isotropic Systems, Ltd.Inventors: Daniel F. Difonzo, Jeremiah P. Turpin

Patent number: 10958334Abstract: 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.Type: GrantFiled: January 2, 2020Date of Patent: March 23, 2021Assignee: The Boeing CompanyInventor: Scott Charles Sullivan

Patent number: 10911395Abstract: Approaches presented herein enable tailoring messages to enhance sharing and resonance based on a community fingerprint and a key influencer. More specifically, a message to be directed to members of an online social community is received. Members of the social community who influence the social community and their likelihood to re-share messages are identified. A re-share fingerprint for the identified influencer is generated that maps the influencer's likelihood to re-share content. A communications fingerprint of the community is also created using an amalgamation of the communication patterns and styles of individual members of the community. The received message is optimized to most effectively target the message to the online social community and to solicit a desired response from the community based on the community communication fingerprint. The optimized message can then be forwarded to the online social community.Type: GrantFiled: June 26, 2019Date of Patent: February 2, 2021Assignee: International Business Machines CorporationInventors: Nathaniel J.

Patent number: 10820235Abstract: A method for balancing inroute traffic load that contains both guaranteed QoS and best effort traffic. Hierarchical grouping levels are defined with the lowest level corresponding to inroutes within the system. Certain levels have common symbol rates, modulation rates, or both. When a new terminal requires admission, it is assigned to entries in the different hierarchical levels so that the inroute traffic load across all levels are balanced. Terminals are admitted to inroutes based, in part, on their channel quality indicator. Inroute traffic load can periodically rebalance based on elapsed time or terminal redistribution.Type: GrantFiled: January 25, 2019Date of Patent: October 27, 2020Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: Satyajit Roy, Archana Gharpuray
