Space information recorder, danger analysis system, danger analysis method, mega-constellation business device, ssa business device, rocket launch business device, satellite business device, debris removal business device, orbital transfer business device, and oadr

A danger analysis system comprising a space information recorder and a management business device, the space information recorder acquiring orbit forecast information from the management business device that is used by a management business operator that manages a plurality of space objects flying in space and recording the orbit forecast information,

• wherein the space information recorder includes two or more categories of
• a category, acquired from a mega-constellation business device, of different constellations formed at nearby altitudes by a same business operator, the mega-constellation business device being a management business device of a satellite group constituting a mega-constellation composed of 100 or more satellites;
• a category of a satellite group of each constellation that flies at a same nominal altitude and cooperatively realizes a same mission;
• a category of orbital planes;
• a category of each orbital plane of the orbital planes;
• and
• a category of an individual satellite, and
• includes information on upper and lower limit values of an orbital altitude or on a nominal altitude and an altitude fluctuation width for each category, and
• wherein the management business device foresees a collision risk between two space objects of the plurality of space objects in advance so as to avoid a collision.
