stations (see No. 1.83). Such use shall be in accordance with Resolution 416 (WRC-07) and shall not cause harmful interference to, or claim protection from, the fixed–satellite and fixed services. Any such use does not preclude the use of this frequency band by other mobile service applications or by other services to which this frequency band is allocated on a co-primary basis and does not establish priority in the Radio Regulations.     (WRC-15)

    458 In the band 6 425–7 075 MHz, passive microwave sensor measurements are carried out over the oceans. In the band 7 075–7 250 MHz, passive microwave sensor measurements are carried out. Administrations should bear in mind the needs of the Earth exploration–satellite (passive) and space research (passive) services in their future planning of the bands 6 425–7 025 MHz and 7 075–7 250 MHz.

    458A In making assignments in the band 6 700–7 075 MHz to space stations of the fixed–satellite service, administrations are urged to take all practicable steps to protect spectral line observations of the radio astronomy service in the band 6 650–6 675.2 MHz from harmful interference from unwanted emissions.

    458B The space-to-Earth allocation to the fixed–satellite service in the band 6 700–7 075 MHz is limited to feeder links for non-geostationary-satellite systems of the mobile–satellite service and is subject to coordination under No. 9.11A. The use of the band 6 700–7 075 MHz (space-to-Earth) by feeder links for non-geostationary-satellite systems in the mobile–satellite service is not subject to No. 22.2.

    459 Additional allocation:  in the Russian Federation, the frequency bands 7 100–7 155 MHz and 7 190–7 235 MHz are also allocated to the space operation service (Earth-to-space) on a primary basis, subject to agreement obtained under No. 9.21. In the frequency band 7 190–7 235 MHz, with respect to the Earth exploration–satellite service (Earth-to-space), No. 9.21 does not apply.     (WRC-15)

    460 No emissions from space research service (Earth-to-space) systems intended for deep space shall be effected in the frequency band 7 190–7 235 MHz. Geostationary satellites in the space research service operating in the frequency band 7 190–7 235 MHz shall not claim protection from existing and future stations of the fixed and mobile services and No. 43A does not apply.     (WRC-15)

    460A The use of the frequency band 7 190–7 250 MHz (Earth-to-space) by the Earth exploration–satellite service shall be limited to tracking, telemetry and command for the operation of spacecraft. Space stations operating in the Earth exploration–satellite service (Earth-to-space) in the frequency band 7 190–7 250 MHz shall not claim protection from existing and future stations in the fixed and mobile services, and No. 43A does not apply. No. 17 applies. Additionally, to ensure protection of the existing and future
