ITU-R SA.1862-2010 Guidelines for efficient use of the band 25.5-27.0 GHz by the Earth exploration-satellite service (space-to-Earth) and space research service (space-to-Earth)
This Recommendation contains guidelines for optimized use of the frequency band 25.5-27.0 GHz between a number of different space science systems, such as near-Earth and deep-space research networks, Earth exploration systems, geostationary-satellite systems and data relay satellite networks. The Recommendation also identifies reduced power flux-density limits for geostationary satellites to offer better protection to space research missions with sensitive space-to-Earth links. It also specifies a power flux-density limit at the GSO for protection of data relay system satellites.
