Engineering Contradiction Analysis
1Productivity
If the number of orbital planes and the number of satellites in an orbital plane increase, then the satellite constellation capacity and coverage are improved, but the collision risk between satellites increases
Solution Approach 1:
The patent segments the space traffic management system into multiple independent business devices, each managing specific satellite constellations. Each business device operates autonomously with its own space traffic management device, allowing localized collision avoidance without affecting the entire constellation system. This segmentation enables scalable expansion of satellite numbers while maintaining safety through distributed management.
Solution Approach 2:
The patent introduces a space traffic management system as an intermediary layer between multiple business devices. This intermediary system provides centralized coordination and communication protocols that facilitate safe interaction between satellites in different orbital planes, reducing collision risks while supporting high constellation capacity through standardized interfaces and data sharing mechanisms.
2Area of stationary object
If satellites are arranged in multiple orbital planes with the same orbital altitude, then the coverage and service capability are improved, but the collision risk at intersection points increases
Solution Approach 1:
The patent implements preliminary action by having space traffic management devices continuously monitor and predict the trajectories of satellites before potential collision points. The system performs advance calculations of relative positions and velocities, enabling preventive maneuvers to be executed before satellites reach critical intersection points, thereby eliminating collision risks while maintaining multi-plane orbital arrangements for optimal coverage.
Solution Approach 2:
The patent establishes feedback mechanisms where business devices continuously report satellite status and position data to the space traffic management system. The system processes this information in real-time and provides feedback instructions for collision avoidance maneuvers. This closed-loop feedback system enables dynamic adjustment of satellite trajectories at intersection points while preserving the overall coverage effectiveness of the multi-plane constellation.
