A space traffic management method of ensuring flight safety by connecting space traffic management devices individually mounted in business devices which are

• a mega-constellation business device which manages a mega-constellation consisting of 100 or more satellites, and
• a first business device and a second business device which manage a space object,
• with each other via a communication line,
• wherein the space traffic management device mounted in the mega-constellation business device
• specifies one to a plurality of representative satellites from a mega-constellation satellite group flying on orbits having a same nominal orbital altitude, has quasi-real-time high-accuracy orbital information of the representative satellite and orbital information relative values of constituent satellites other than the representative satellite, relative to the representative satellite, and shares the quasi-real-time high-accuracy orbital information of the representative satellite and the orbital information relative values of the constituent satellites relative to the representative satellite,
• with the space traffic management devices mounted in the second business device,
• wherein the second business device
• comprises a space information recorder, a danger analysis device, and a danger avoidance action assist device, and
• records the quasi-real-time high-accuracy orbital information of the representative satellite, the orbital information relative values of the constituent satellites relative to the representative satellite, and information of the space object, to the space information recorder, the quasi-real-time high-accuracy orbital information and the orbital information relative values being acquired from the space traffic management device mounted in the mega-constellation business device, the information of the space object being acquired from the space traffic management device mounted in the first business device,
• wherein the danger analysis device
• derives collision avoidance information including a timing or a condition at which or under which collision does not occur with any one of satellites constituting a plurality of mega-constellation satellite groups, and
• wherein the danger avoidance action assist device notifies the first business device of the collision avoidance information.

A space traffic management method of ensuring flight safety by connecting space traffic management devices individually mounted in business devices which are

• a mega-constellation business device to manage a mega-constellation consisting of 100 or more satellites, and
• a debris removal business device to manage a debris removal satellite, or a rocket launch business device,
• with each other via a communication line,
• wherein the space traffic management device mounted in the mega-constellation business device
• specifies one to a plurality of representative satellites from a mega-constellation satellite group flying on orbits having a same nominal orbital altitude, has quasi-real-time high-accuracy orbital information of the representative satellite, and orbital information relative values of constituent satellites, other than the representative satellite, relative to the representative satellite, and shares the quasi-real-time high-accuracy orbital information of the representative satellite and the orbital information relative values of the constituent satellites relative to the representative satellite, with the space traffic management device mounted in the debris removal business device or the rocket launch business device,
• wherein the debris removal business device or the rocket launch business device
• includes a space information recorder and a danger analysis device, and
• records the quasi-real-time high-accuracy orbital information of the representative satellite, the orbital information relative values of the constituent satellites relative to the representative satellite, and orbital-descent planned orbital information of a debris removal satellite, or planned orbital information for rocket launch, to the space information recorder, the quasi-real-time high-accuracy orbital information and the orbital information relative values being acquired from the space traffic management device mounted in the mega-constellation business device, and
• wherein the danger analysis device
• derives a timing and an orbital condition at which and under which collision does not occur with any one of satellites constituting a mega-constellation satellite groups.
