Abstract:
This work provides an update on international space standards activities relevant to the United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS), with a focus on liaison efforts between ISO Technical Committee 20, Subcommittee 14 (ISO TC20/SC14), CCSDS, and the UN long-term sustainability (LTS) framework. It reviews recent and ongoing standards development related to Space Traffic Coordination (STC), collision avoidance, launch collision avoidance (LCOLA), and space data exchange, highlighting how these standards operationalize UN LTS guidelines. The presentation summarizes progress on key CCSDS message standards, including updates to the Conjunction Data Message and the development of the Launch Data Message, emphasizing interoperability, data integrity, and harmonized terminology. It outlines the structure and scope of ISO standards such as ISO 9490 (STC), ISO 23705 (collision avoidance), and ISO 21740 (LCOLA), and explains how responsibilities and data-sharing expectations are distributed across operators, SSA providers, and launch entities. The work discusses areas of international consensus and remaining points of divergence, including registration practices, thresholds, and applicability across orbital regimes. It concludes that coordinated standards development through ISO and CCSDS is a critical mechanism for translating UN policy goals into practical, globally adopted practices that enhance space safety, sustainability, and operational transparency.
