NGSO COMMUNICATION APPARATUS FOR EXTENDING OPERATION TIME AND REDUCING NUMBER OF SATELLITES USING ATC, AND ATC AND OPERATING METHOD THEREOF

摘要

Disclosed are a non geostationary satellite orbit (NGSO) communication apparatus that extends an operation time using an ancillary territory component (ATC) and reduces a number of satellites, and an ATC and an operating method thereof. The NGSO communication apparatus for extending an operation time using an ATC and reducing a number of satellites may include a first ATC that communicates with a mobile earth station (MES), and a second ATC that communicate with the first ATC to relay data between the MES and the satellite when the first ATC is unable to communication with the satellite revolving along an orbit.
