Innovation Solution
A space traffic management system with connected space traffic management devices in collision avoidance assist and mega-constellation business devices, utilizing a database for orbital information, an orbital analysis unit, an announcement unit, and a collision analysis unit to predict and prevent collisions, and a countermeasure formulation unit to implement avoidance strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mega-constellation satellites operate in unsteady phases (orbit insertion, orbital disposal), then operational flexibility is improved, but collision risk increases
Solution Approach 1:
The system performs preliminary collision risk assessment by analyzing orbital information of unsteady-operation space objects against steady-operation mega-constellation satellite groups before collisions can occur. The database stores preprocessed orbital data, and the analysis unit identifies potential collision scenarios in advance, allowing proactive avoidance maneuvers to be planned and executed.
2Reliability
If collision avoidance frameworks are established for mega-constellations, then flight safety is improved, but system complexity increases
Solution Approach 1:
The collision avoidance system is segmented into distinct functional modules: a database for storing orbital information, an analysis unit for identifying collision risks, and communication interfaces for coordinating avoidance maneuvers. This modular architecture allows each component to be developed, tested, and maintained independently, reducing overall system complexity while ensuring comprehensive collision avoidance coverage.

AI summary
An orbital analysis unit (431) of a collision avoidance assist business device identifies a mega-constellation satellite group formed in an orbital altitude which the mega-constellation satellite group is anticipated to pass during a flight of an unsteady-operation space object. An announcement unit (432) of the collision avoidance assist business device announces a danger alarm and orbital information of the unsteady-operation space object, to a mega-constellation business device which manages the mega-constellation satellite group. A collision analysis unit (411) of a satellite mega-constellation business device analyzes collision of the unsteady-operation space object with an individual satellite constituting the mega-constellation satellite group. A countermeasure formulating unit (412) of the satellite constellation business device formulates a collision avoidance countermeasure when collision is predicted.
