  • Communication method and apparatuses performing the same
    Patent number: 10911133
    Abstract: Disclosed is a communication method performed between a satellite and a ground station and apparatuses performing the communication method. The communication method includes transmitting a plurality of frames based on a beam allocation time schedule (BATS) between a satellite and a ground station, and synchronizing the BATS based on a reception time and a detection time of one or more frames among the plurality of frames to be received through a beam open window (BOW) allocated to the ground station.
    Type: Grant
    Filed: November 5, 2018
    Date of Patent: February 2, 2021
    Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE
    Inventors: Jonggyu Oh, Pansoo Kim, Deock Gil Oh, Joon Gyu Ryu, Soo Yeob Jung

  • Network synchronization apparatus and method of time division multiple access (TDMA)-based mesh network satellite communication system
    Patent number: 10057869
    Abstract: Disclosed is a network synchronization apparatus and method of a time division multiple access (TDMA)-based mesh network satellite communication system, the network synchronization method of a terminal in a satellite communication system including receiving timing error information from a central station, generating a mesh superframe start time (SST?) by reversing a sign of the timing error information, and receiving traffic information transmitted by a transmission terminal using the mesh SST?.
