aeronautical radionavigation service is limited to Doppler navigation aids.

    498A The Earth exploration–satellite (active) and space research (active) services operating in the band 13.25–13.4 GHz shall not cause harmful interference to, or constrain the use and development of, the aeronautical radionavigation service.     (WRC-97)

    499 Additional allocation:  in Bangladesh and India, the band 13.25–14 GHz is also allocated to the fixed service on a primary basis. In Pakistan, the band 13.25–13.75 GHz is allocated to the fixed service on a primary basis.     (WRC-12)

    499A The use of the frequency band 13.4–13.65 GHz by the fixed–satellite service (space-to-Earth) is limited to geostationary–satellite systems and is subject to agreement obtained under No. 9.21 with respect to satellite systems operating in the space research service (space-to-space) to relay data from space stations in the geostationary-satellite orbit to associated space stations in non-geostationary satellite orbits for which advance publication information has been received by the Bureau by 27 November 2015.     (WRC-15)

    499B Administrations shall not preclude the deployment and operation of transmitting earth stations in the standard frequency and time signal–satellite service (Earth-to-space) allocated on a secondary basis in the frequency band 13.4–13.65 GHz due to the primary allocation to the fixed satellite service (space-to-Earth).     (WRC-15)

    499C The allocation of the frequency band 13.4–13.65 GHz to the space research service on a primary basis is limited to:
         * satellite systems operating in the space research service (space-to-space) to relay data from space stations in the geostationary-satellite orbit to associated space stations in non-geostationary satellite orbits for which advance publication information has been received by the Bureau by 27 November 2015,
         * active spaceborne sensors,
         * satellite systems operating in the space research service (space-to-Earth) to relay data from space stations in the geostationary-satellite orbit to associated earth stations.
     Other uses of the frequency band by the space research service are on a secondary basis.     (WRC-15)

    499D In the frequency band 13.4–13.65 GHz, satellite systems in the space research service (space-to-Earth) and/or the space research service (space-to-space) shall not cause harmful interference to, nor claim protection from, stations in the fixed, mobile, radiolocation and Earth exploration–satellite (active) services.     (WRC-15)

    499E In the frequency band 13.4–13.65 GHz, geostationary-satellite networks in the fixed–satellite service (space-to-Earth) shall not claim protection from space stations in the Earth exploration–satellite service (active) operating in accordance with the Radio Regulations, and No. 43A does not apply. The provisions of No. 22.2 do not apply to the Earth exploration–satellite service (active) with respect to the fixed–satellite service (space-to-Earth) in this frequency band.     (WRC-15)

    500 Additional allocation:  in Algeria, Saudi Arabia, Bahrain, Brunei Darussalam, Cameroon, Egypt, the United Arab Emirates, Gabon, Indonesia, Iran (Islamic Republic of), Iraq, Israel, Jordan, Kuwait, Lebanon, Madagascar, Malaysia, Mali, Morocco,
