47 CFR 25.261 - Sharing among NGSO FSS space stations. | US Law | LII / Legal Information Institute
Absent coordination between two or more satellite systems, whenever the increase in system noise temperature of an earth station receiver, or a space station receiver for a satellite with on-board processing, of either system, ΔT/T, exceeds 6 percent due to interference from emissions originating in the other system in a commonly authorized frequency band, such frequency band will be divided among the affected satellite networks in accordance with the following procedure

Resolution 609 (Rev. WRC-07) Consultation meeting
via Alex Epshteyn

"The World Radiocommunication Conference, Geneva 2003 (WRC-03), adopted Resolution 609 (Rev. WRC-07), whereby Consultation Meetings between administrations operating or planning to operate systems in the aeronautical radionavigation service (ARNS) and systems in the radionavigation-satellite service (RNSS) in the 1 164-1 215 MHz frequency band, should be held on a regular basis to achieve the level of protection for ARNS systems foreseen in resolves 1 of that Resolution. For more information see CR/202."

Space Data Association - about
The Space Data Association (SDA) is an organization that brings together satellite operators who value controlled, reliable and efficient data-sharing critical to the safety and integrity of the space environment and the RF spectrum. The SDA membership includes the world’s major satellite communications companies. The Executive members, the world’s four largest commercial satellite operators, are, Inmarsat, Intelsat, SES and Eutelsat.
