Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional centralized data storage and communication systems are used in space systems, then system complexity is reduced and ease of operation is maintained, but security and data integrity are compromised when multiple organizations are involved
Solution Approach 1:
The patent introduces a blockchain network as an intermediary layer between multiple space system organizations. This mediator enables secure data sharing and communication without requiring direct trust relationships between parties, resolving the contradiction by providing security through the intermediary's decentralized consensus mechanism rather than through complex organizational agreements
2Reliability
If blockchain technology is implemented for secure data sharing among multiple organizations, then data security and integrity are improved, but system complexity increases
Solution Approach 1:
The patent implements a universal blockchain framework that serves multiple functions simultaneously: secure data storage, communication authentication, configuration management, and orbital data sharing. This multi-functional approach reduces the need for separate security systems for each function, thereby mitigating the increase in system complexity while maintaining comprehensive security
3Reliability
If distributed ledger technology is used for satellite configuration management, then data integrity and security are enhanced, but ease of operation deteriorates due to complex interfaces and procedures
Solution Approach 1:
The patent implements smart contracts that automatically execute configuration management tasks and validate data integrity without requiring manual intervention. The system performs self-verification and self-management of satellite configurations, eliminating the need for complex manual procedures while maintaining data integrity through automated consensus mechanisms
4Reliability
If traditional communication protocols are used for orbital data sharing, then ease of operation is maintained, but security and privacy protection are insufficient for multi-organization collaboration
Solution Approach 1:
The patent merges traditional communication protocols with blockchain verification mechanisms into a unified communication framework. This combination integrates security features directly into the communication flow rather than adding separate security layers, thereby enhancing communication security while minimizing the increase in system complexity

AI summary
A framework for interfacing a blockchain-based ground system with flight software and satellite orbit analysis applications is disclosed. A blockchain application (e.g., a web application) for secure management of satellites has three components—a client, a server, and a private and permissioned-based blockchain network (e.g., a Hyperledger Fabric™ network). The client allows users to configure satellite parameters. The server facilitates the communication between the client and the blockchain. The blockchain allows the secure management and storage of satellite configuration data on blockchain ledgers. For instance, SECCON provides a blockchain-based framework that can be a potential candidate for next generation ground system applications. SECCON allows secure configuration management of satellites, and has been interfaced with OpenSatKit, a software tool kit that can interact with the cFS. SECCON also provides secure communication of orbital data between trusted organizations and allows the satellite configuration parameters to be exported and viewed in SOAP.
