SSRSSG

SSRSSG stands for Satellite Safety, Resilience and Security Standards Group, an international consortium focused on developing and promoting technical standards for space systems. Founded in 2016 by a coalition of space agencies, major aerospace companies, and research institutions, SSRSSG aims to improve safety, resilience to anomalies, and security of satellites and related ground infrastructure.

Its remit covers lifecycle stages from concept and design to manufacturing, launch, operations, and end-of-life disposal, including ground-segment operations. Core topics include cyber-physical security, software assurance, risk management, radiation tolerance, supply-chain integrity, and incident response. SSRSSG publishes non-binding standards, best-practice guides, and testing methodologies; documents are produced by volunteer working groups and released after public review.

Governance rests with an international steering committee that oversees the organization, complemented by a rotating chair and a secretariat coordinating activities. Members include national space agencies, major satellite operators, and industry partners. Participation is open to government entities, academia, and industry groups, with decisions typically requiring consensus or a supermajority.

Impact and adoption of SSRSSG standards vary by organization and region, but they influence design and procurement choices among member entities and can inform national regulatory or policy discussions. Some members map internal standards to SSRSSG guidance, and pilot programs illustrate applicability to small-satellite constellations and critical ground infrastructure.

Criticism and challenges include the voluntary nature of the standards and uneven global uptake. Some observers argue that the group must adapt rapidly to evolving cyber threats and navigate competing national security considerations. Ongoing work emphasizes interoperability, clearer conformance guidance, and alignment with international norms.
