The need to improve registration practices in the context of space traffic management.

This paper examines the legal basis and framework for the United Nations registration process for space objects. UN registration processes are compared against and contrasted with national and regional registration processes to highlight potential adjustments in light of the need for a space traffic management system. While there are shortfalls in compliance and monitoring of States' responsibility to adhere to UN registration requirements, the growing importance of space traffic management is providing a catalyst for reform and recommitment to the ideals upon which the 1975 UN Registration Convention was based. Since the data provided to national registries and the UN register is not detailed enough and is not sufficient for creating a space traffic management regime, it is recommended that (1) the recommendations concerning the registration of space objects belonging to a large constellation that were agreed by the UNCOPUOS Working Group on the Status and Application of the Five United Nations Treaties on Outer Space in 2023 are implemented to ensure uniformity of registration practice regarding large constellations; (2) States incentivize good registration practices by other States, for instance by requiring that satellites of commercial actors are registered by the relevant launching State as a condition for market access; (3) the importance of furnishing additional information on the subsequent activity and status of objects, as required by the Registration Convention, UN General Assembly resolutions 1721 (XVI) B and 62/101 and Guideline A.5 para 2 of the UNCOPUOS Guidelines on the Long-Term Sustainability of Space Activities, be underlined. • Overview of the UN registration process, including hard law and soft law, in light of space traffic management. • Analysis of the registration processes and practices of the USA, China, Russia and ESA. • Suggestions on enhancing registration practices and processes in light of space traffic management. • Overview of primary sources on registration.
