Final action.

Summary

The Federal Communications Commission’s Space Bureau has issued a final rule that updates the “reference links” used to coordinate the frequencies of geostationary (GSO) satellite networks that provide broadband services. By aligning these reference links with the typical operating patterns of U.S. satellite systems, the rule aims to make better use of the radio‑frequency spectrum and reduce interference among the growing number of broadband satellites that share the same orbital slots. The rule applies to commercial satellite operators that run GSO broadband constellations, as well as any other entities—such as ground‑station providers and federal agencies—that rely on the same spectrum bands. It is part of the broader “Modernizing Spectrum Sharing for Satellite Broadband” initiative, which seeks to keep the United States’ satellite communications competitive and reliable. The final rule was published in the Federal Register on November 5, 2026 (91 FR 69725) and became effective on December 7, 2026. With the rule now in force, satellite operators must use the updated reference links for future network planning and coordination. The FCC will monitor implementation and may issue further guidance or adjustments as the satellite broadband market continues to evolve.

Official abstract

In this document, the Space Bureau (Bureau or we) within the Federal Communications Commission (Commission) updates the initial set of geostationary (GSO) satellite network reference links adopted in the Modernizing Spectrum Sharing for Satellite Broadband Report and Order (Order). Ensuring the GSO reference links appropriately reflect typical and widespread GSO satellite operations in the United States will promote efficient spectrum sharing among today's broadband satellite systems.
