Title:
COMMUNICATION SATELLITE, SATELLITE CONSTELLATION, INTER-SATELLITE COMMUNICATION METHOD, ARTIFICIAL SATELLITE, AND GROUND FACILITY
Document Type and Number:
WIPO Patent Application WO/2022/249832
Kind Code:
A1
Abstract:
A communication satellite (200A) flies in an orbit (21) of orbital inclination angle θideg and is equipped with a communication device (51) having a view change range of ±θideg with respect to a +X axis about a Z axis, with the direction of +Z axis facing the positive direction on right-hand orthogonal coordinates being a geocentric direction, and the direction of +X axis facing the positive direction on right-hand orthogonal coordinates being a movement direction. The communication satellite (200A), when passing through the right ascension of an ascending node, communicates with a communication satellite (201) flying on the northern side from the equatorial plane (401) in an orbit (22) adjacent in the longitudinal direction of a normal vector to the orbital plane of the orbit (21). Therefore, a communication line between the communication satellite (200A) and the communication satellite (201) is not disrupted even when the adjacent orbits change positions to the left and right of each other at the northernmost end of the orbital plane.
