Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of satellites and debris in space, combined with improved ground-based monitoring capabilities, poses challenges for conventional alarm services like those run by the US CSpOC, particularly in preventing collisions and managing space traffic effectively.
Innovation Solution
A space traffic management system that includes a device capable of recording orbital information and implementing flight safety measures for satellite groups. This system uses a satellite group ID to identify cooperating satellites and incorporates flight security measure information to ensure safe operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional alarm service is used to manage space objects, then the system is simple to operate, but it cannot effectively handle the increased number of satellites and debris
Solution Approach 1:
The patent segments space objects into satellite groups based on nominal orbital altitude, with each group identified by a unique satellite group ID. This segmentation allows the complex task of managing numerous satellites and debris to be divided into manageable groups, improving productivity while maintaining operational simplicity through group-based classification.
Solution Approach 2:
The patent introduces a new dimension of classification by adding satellite group ID as an additional identifier beyond individual satellite IDs. This dimensional addition enables efficient grouping and management of space objects without increasing operational complexity, as the grouping provides an extra layer of organization for traffic management.
2Reliability
If individual satellite management is implemented, then collision avoidance is precise, but the management burden increases significantly with mega-constellations
Solution Approach 1:
The patent merges management of multiple satellites into satellite groups sharing the same nominal orbital altitude and identified by a common satellite group ID. This merging maintains precise collision avoidance within groups while reducing overall management complexity by treating groups as unified entities rather than managing each satellite individually.
Solution Approach 2:
The patent applies partial action by implementing group-based management for satellites at the same orbital altitude rather than requiring individual management of all satellites. This partial approach provides sufficient collision avoidance effectiveness for grouped satellites while significantly reducing management burden compared to complete individual management.
3Measurement precision
If detailed orbital information is recorded for all satellites, then monitoring precision is high, but data storage and processing requirements increase
Solution Approach 1:
The patent segments orbital data management by satellite group ID, recording detailed orbital information for each group rather than for every individual satellite. This segmentation maintains high monitoring precision within groups while reducing total data volume by eliminating redundant information across satellites sharing the same orbital characteristics.
Solution Approach 2:
The patent applies local quality by recording comprehensive orbital information at the group level for satellites with similar orbital characteristics. This approach ensures high monitoring precision where needed (within each orbital group) while reducing overall data storage requirements by not duplicating identical orbital data across multiple satellites.

AI summary
Having as its objective to take flight safety measure per satellite group, a space information recorder (101) is mounted in a mega-constellation satellite business device being a business device that manages a satellite constellation of 100 or more satellites, or in a constellation satellite business device being a business device that manages a satellite constellation of 10 or more satellites. The space information recorder (101) is provided with a category of a satellite group ID (112) which identifies a satellite group in which a group of a plurality of satellites having the same nominal orbital altitude cooperate with each other to fulfill a mission. The category of the satellite group ID (112) includes flight safety measure information (115) expressing flight safety measure of the satellite group.
