Abstract

An object is to appropriately manage disclosure of information on the orbit of a satellite constellation. An information management device is installed in at least one of a plurality of management business devices each of which conducts a management business for a plurality of space objects flying in space. A storage unit stores orbit forecast information including an orbit forecast, which is a forecast value of an orbit of each of the plurality of space objects, and a forecast error that is forecast for the orbit. An information disclosure unit determines whether the orbit forecast information is to be disclosed to a different information management device, based on a disclosure threshold for determining whether the orbit forecast information is to be disclosed and the forecast error.
