practicable efforts to avoid the implementation of new fixed-service stations in these bands.     (WRC-19)

    362A In the United States, in the bands 1 555–1 559 MHz and 1 656.5–1 660.5 MHz, the aeronautical mobile–satellite (R) service shall have priority access and immediate availability, by pre-emption if necessary, over all other mobile–satellite communications operating within a network. Mobile–satellite systems shall not cause unacceptable interference to, or claim protection from, aeronautical mobile–satellite (R) service communications with priority 1 to 6 in Article 44. Account shall be taken of the priority of safety-related communications in the other mobile–satellite services.     (WRC-97)

    364 The use of the band 1 610–1 626.5 MHz by the mobile–satellite service (Earth-to-space) and by the radiodetermination–satellite service (Earth-to-space) is subject to coordination under No. 9.11A. A mobile Earth station operating in either of the services in this band shall not produce a peak e.i.r.p. density in excess of −15 dB(W/4 kHz) in the part of the band used by systems operating in accordance with the provisions of No. 366 (to which No. 4.10 applies), unless otherwise agreed by the affected administrations. In the part of the band where such systems are not operating, the mean e.i.r.p. density of a mobile Earth station shall not exceed −3 dB(W/4 kHz). Stations of the mobile–satellite service shall not claim protection from stations in the aeronautical radionavigation service, stations operating in accordance with the provisions of No. 366 and stations in the fixed service operating in accordance with the provisions of No. 359. Administrations responsible for the coordination of mobile–satellite networks shall make all practicable efforts to ensure protection of stations operating in accordance with the provisions of No. 366.

    365 The use of the band 1 613.8–1 626.5 MHz by the mobile–satellite service (space-to-Earth) is subject to coordination under No. 9.11A.

    366 The band 1 610–1 626.5 MHz is reserved on a worldwide basis for the use and development of airborne electronic aids to air navigation and any directly associated ground-based or satellite-borne facilities. Such satellite use is subject to agreement obtained under No. 9.21.

    367 Additional allocation:  The frequency band 1 610–1 626.5 MHz is also allocated to the aeronautical mobile–satellite (R) service on a primary basis, subject to agreement obtained under No. 9.21.

    368 The provisions of No. 4.10 do not apply with respect to the radiodetermination–satellite and mobile–satellite services in the frequency band 1 610–1 626.5 MHz. However, No. 4.10 applies in the frequency band 1 610–1 626.5 MHz with respect to the aeronautical radionavigation–satellite service when operating in accordance with No. 366, the aeronautical mobile–satellite (R) service when operating in accordance with No. 367, and in the frequency band 1 621.35–1 626.5 MHz with respect to the maritime mobile–satellite
