Title:
EARTH STATION, RELAY SATELLITE, SATELLITE SYSTEM AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/014460
Kind Code:
A1
Abstract:
There is provided a technique for achieving inter-satellite optical communication for a satellite having a limited calculation capability. One aspect of the present disclosure relates to an earth station, including: a data acquisition unit that acquires a predicted orbit data sequence indicative of a predictive ephemeris of a satellite for a predetermined period, and a communication unit that transmits the acquired predicted orbit data sequence to a relay satellite, wherein the data acquisition unit acquires a first data sequence that is the predicted orbit data sequence having a first data amount and a second data sequence that is the predicted orbit data sequence having a second data amount smaller than the first data amount, and the communication unit transmits the first data sequence or the second data sequence as orbit information of a satellite to a relay satellite, the first data sequence or the second data sequence selected in accordance with predetermined selection criteria.
