Satellite Orbit Forecast Disclosure Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to appropriately manage information on the orbit of a satellite constellation, particularly due to the limited launch window and high risk of collision during rocket launches, especially in mega-constellations.
Innovation Solution
An information management device is installed in management business devices, which includes a storage unit for orbit forecast information and an information disclosure unit that determines whether to disclose this information based on a disclosure threshold and forecast error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If orbit forecast information is disclosed to enable collision avoidance, then collision risk is reduced, but information security and operational stability are compromised
Solution Approach 1:
The patent applies local quality by differentiating the disclosure treatment based on the specific characteristics of orbit forecast information. Not all forecast information is disclosed uniformly; instead, the system identifies and discloses only the specific portions that are necessary for collision avoidance while maintaining operational stability. This selective disclosure approach allows the system to provide collision avoidance capabilities where needed without compromising overall information security.
Solution Approach 2:
The patent implements partial action by disclosing only the essential portions of orbit forecast information required for collision avoidance, rather than providing complete forecast data. The information disclosure unit determines and discloses only the necessary forecast information, avoiding the excessive disclosure that could compromise operational stability while still achieving the collision avoidance objective.
2Reliability
If comprehensive orbit information is managed to ensure safety, then collision risk decreases, but system complexity increases
Solution Approach 1:
The patent applies the extraction principle by separating the collision avoidance function from the general information management system. The information disclosure unit is extracted as a specialized component that handles only the specific task of determining and disclosing orbit forecast information necessary for collision avoidance. This extraction reduces the overall system complexity by isolating the complex information management functions into a dedicated unit.
Solution Approach 2:
The patent implements segmentation by dividing the information management system into distinct functional units: the storage unit for storing orbit forecast information, the information disclosure unit for determining what to disclose, and the disclosure mechanism itself. This segmentation allows each component to handle specific aspects of information management independently, reducing the complexity of the overall system while ensuring comprehensive safety coverage.

AI summary
An object is to appropriately manage disclosure of information on the orbit of a satellite constellation. An information management device is installed in at least one of a plurality of management business devices each of which conducts a management business for a plurality of space objects flying in space. A storage unit stores orbit forecast information including an orbit forecast, which is a forecast value of an orbit of each of the plurality of space objects, and a forecast error that is forecast for the orbit. An information disclosure unit determines whether the orbit forecast information is to be disclosed to a different information management device, based on a disclosure threshold for determining whether the orbit forecast information is to be disclosed and the forecast error.
