ITU Seminar on Science Services in relation to ITU Radio Regulations and WRC-27, MCMC Centre of Excellence, Cyberjaya, Selangor, Malaysia, 9-10 December 2025

The effective management of radiofrequency spectrum is essential to ensuring the continued operation and advancement of critical science services such as meteorology, radioastronomy, space research, and standard frequency and time signal services. These services not only support essential functions such as climate monitoring, natural disaster response, and time synchronization for global infrastructure, but also contribute to international scientific collaboration and innovation. Recognizing their strategic value, this ITU seminar—organized in cooperation with the World Meteorological Organization (WMO)—aims to inform and engage national stakeholders in the regulatory, technical, and operational aspects of science services within the framework of the ITU Radio Regulations and ongoing preparations for WRC-27.

Policymakers and engineers have a pivotal role to play in balancing national spectrum demands with international commitments to protect passive and active science services. The seminar offers a comprehensive overview of the work being carried out within ITU-R Study Group 7 and its Working Parties, covering services such as Earth exploration satellites, time and frequency systems, and space-based weather monitoring. Presentations by leading international experts will highlight current regulatory challenges, WRC-27 agenda items of direct relevance, and the technical criteria needed to safeguard these services from harmful interference.

With increasing competition for spectrum resources, especially in bands adjacent to those used by science services, the protection of these services requires a careful and informed approach. National administrations must be equipped with the latest knowledge on technical requirements, compatibility studies, and international coordination mechanisms to contribute effectively to the WRC-27 process. This seminar supports that objective by promoting a deeper understanding of the operational and regulatory landscape, helping stakeholders align national strategies with global developments.

Ultimately, this seminar serves as a platform for strengthening national readiness for WRC-27. It encourages collaboration between technical experts and policymakers, reinforcing the importance of harmonized spectrum policies that ensure the resilience and continuity of science services while enabling innovation in other radiocommunication sectors.
