This paper explores the integration of blockchain technology, specifically Hyperledger Fabric, with satellite communications to enhance the security and reliability of global navigation satellite systems (GNSS). Given the inherent vulnerabilities in satellite systems, such as the susceptibility to various cyberattacks and the risk posed by GNSS signal attacks, this research proposes a novel security framework. By leveraging blockchain’s decentralized and immutable nature, the paper aims to fortify the integrity and verification of GNSS data. The enhancement of GNSS data integrity and verification is achieved through a consensus mechanism that aim to prevent unauthorized data alterations and provide robust anti-spoofing and anti-jamming capabilities. Integrating blockchain with satellite communications not only ensures data security but also fosters a transparent and decentralized operational model by enhancing the trustworthiness of satellite-derived data. In addition, this paper outlines the current state-of-the-art, the architecture of the proposed solution, and discusses the potential challenges and future research directions in optimizing blockchain for space applications.
