摘要： A scheduler apparatus includes: a calculation unit to determine, on the basis of a time required for switching from a first orbiting satellite that is an orbiting satellite to which an earth station is currently directed to a second orbiting satellite candidate that is an orbiting satellite as a candidate for a second orbiting satellite that is an orbiting satellite to which the earth station is directed next, a future expected throughput between the earth station and the first orbiting satellite, and a future expected throughput between the earth station and the second orbiting satellite candidate, the second orbiting satellite and a switching timing at which the earth station switches a directed satellite from the first orbiting satellite to the second orbiting satellite; and an interface to transmit information on the second orbiting satellite and the switching timing determined by the calculation unit.

摘要： A terminal according to the present invention includes an array antenna including an aperture, and an antenna pattern calculation unit. The antenna pattern calculation unit calculates antenna patterns of the array antenna that divide the aperture to correspondingly orient each of the aperture divisions toward a plurality of relay stations when control frames are received, and orient the aperture toward one of the plurality of relay stations when a data frame is received.
