Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of satellites and space debris in orbit, combined with improved ground-based monitoring capabilities, makes it challenging for the US CSpOC to continue conventional alarm services effectively.
Innovation Solution
A space traffic management system that includes multiple space traffic management devices, each equipped with a space information recorder, danger alarm device, danger analysis device, danger avoidance action assist device, and security device, allowing for efficient sharing and analysis of space object data among management business operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the US CSpOC continues conventional alarm services, then collision avoidance can be achieved, but the system becomes overwhelmed by the increasing number of satellites and space debris
Solution Approach 1:
The patent divides the centralized monitoring system into multiple distributed space traffic management devices operated by different business operators. Each device independently monitors and manages space objects within its responsibility, segmenting the overwhelming monitoring task into manageable portions that can be handled concurrently without overloading a single system.
Solution Approach 2:
The patent combines multiple space traffic management devices from different business operators into a cooperative network. These devices share space object information and coordinate their monitoring efforts, merging their individual capabilities to achieve comprehensive coverage of the increasing number of satellites and debris without requiring a single overly complex centralized system.
2Ease of operation
If multiple business operators manage space objects independently, then operational autonomy is maintained, but collision danger analysis efficiency decreases
Solution Approach 1:
The patent introduces a standardized information sharing interface as an intermediary between independent business operators. This interface enables automated exchange of space object data and collision danger analysis results, allowing operators to maintain independence while achieving coordinated efficiency through standardized communication protocols that facilitate rapid information exchange.
3Reliability
If space object information is shared among multiple operators, then collision avoidance improves, but information security and falsification risks increase
Solution Approach 1:
The patent implements preliminary verification of space object information at the source before sharing. Each space traffic management device validates the authenticity and accuracy of information it generates or receives, performing security checks in advance to prevent falsified data from entering the shared network, thus maintaining reliability while enabling information exchange.

AI summary
To achieve an objective to enable a plurality of management business operators managing space objects flying in space, to share and carry out danger analysis efficiently. In a space traffic management system, a plurality of space traffic management devices are connected to each other via a communication line. Each of the plurality of space traffic management devices includes a space information recorder, a danger alarm device, a danger analysis device, a danger avoidance action assist device, and a security device. The space information recorder includes a space object ID, orbital information, and public condition information; and a business device ID and public condition information. The plurality of space traffic management devices have data format compatibility and share the space object ID and the business device ID, and share orbital information corresponding to the space object ID among business devices that comply with the public condition information.
