562E The allocation to the Earth exploration–satellite service (active) is limited to the band 133.5–134 GHz. (WRC-2000)

562H Use of the bands 174.8–182 GHz and 185–190 GHz by the inter–satellite service is limited to satellites in the geostationary-satellite orbit. The single-entry power flux-density produced by a station in the inter–satellite service, for all conditions and for all methods of modulation, at all altitudes from 0 to 1 000 km above the Earth’s surface and in the vicinity of all geostationary orbital positions occupied by passive sensors, shall not exceed −144 dB(W/(m2·MHz)) for all angles of arrival. (WRC-2000)

563A In the bands 200–209 GHz, 235–238 GHz, 250–252 GHz and 265–275 GHz, ground-based passive atmospheric sensing is carried out to monitor atmospheric constituents. (WRC-2000)

563AA In the frequency band 235-238 GHz, stations in the Earth exploration-satellite service (passive) shall not claim protection from stations in the fixed and mobile services. (WRC-23)

563B The band 237.9–238 GHz is also allocated to the Earth exploration–satellite service (active) and the space research service (active) for spaceborne cloud radars only. (WRC-2000)
