The 23rd consultation meeting on International Telecommunication Union resolution 609 was held in Washington, USA from November 3 to 5, 2026. Representatives from 17 countries and regions participated in the discussions. The purpose of the International Telecommunication Union resolution 609 consultation meeting is to determine the power share of each country's satellite navigation system in the 1164-1215 MHz band space radio through a consultation mechanism and strictly ensure that the total power of all systems does not exceed the specified limit, so as to protect aviation radio navigation services within this band from harmful interference. During the conference, the Chinese delegation coordinated multilateral coordination, focused on promoting the calculation and negotiation of single input and aggregate equivalent power flux densities, and actively participated in the formulation of international standards. The Radio Administration Bureau of the Ministry of Industry and Information Technology organized the National Radio Spectrum Management Center and relevant satellite operators to attend the conference.
