Abstract

A space information recorder ( 100 ) acquires space object information ( 500 ), which is orbit forecast information of a plurality of space objects ( 60 ), from a management business device ( 40 ) used by a management business operator that manages the plurality of space objects ( 60 ), and records the space object information ( 500 ). The space object information ( 500 ) includes a forecast epoch, a forecast orbital element, and a forecast error of each of the plurality of space objects ( 60 ). When it is foreseen that a space object A included in the plurality of space objects ( 60 ) will intrude into a range at orbital altitudes of 300 km to 1000 km in which a satellite group of LST 10:00 to 11:00 is present, a time period from intrusion to exit and orbit forecast information are recorded.
