in the broadcasting–satellite service using the geostationary-satellite orbit.     (WRC-2000)

    562 The use of the band 94–94.1 GHz by the Earth exploration–satellite (active) and space research (active) services is limited to spaceborne cloud radars.     (WRC-97)

    562A In the bands 94–94.1 GHz and 130–134 GHz, transmissions from space stations of the Earth exploration–satellite service (active) that are directed into the main beam of a radio astronomy antenna have the potential to damage some radio astronomy receivers. Space agencies operating the transmitters and the radio astronomy stations concerned should mutually plan their operations so as to avoid such occurrences to the maximum extent possible.     (WRC-2000)

    562B In the frequency bands 105–109.5 GHz, 111.8–114.25 GHz and 217–226 GHz, the use of this allocation is limited to space-based radio astronomy only.     (WRC-19)

    562C Use of the band 116–122.25 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 km 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 −148 dB(W/(m2·MHz)) for all angles of arrival.     (WRC-2000)

    562D Additional allocation:  in Korea (Rep. of), the frequency bands 128–130 GHz, 171–171.6 GHz, 172.2–172.8 GHz and 173.3–174 GHz are also allocated to the radio astronomy service on a primary basis. Radio astronomy stations in Korea (Rep. of) operating in the frequency bands referred to in this footnote shall not claim protection from, or constrain the use and development of, services in other countries operating in accordance with the Radio Regulations.     (WRC-15)

    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)

    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)

    564A For the operation of fixed and land mobile service applications in frequency bands in the range 275–450 GHz:
     The frequency bands 275–296 GHz, 306–313
