communications operating within a network. Mobile–satellite systems shall not cause unacceptable interference to, or claim protection from, distress, urgency and safety communications of the GMDSS. Account shall be taken of the priority of safety-related communications in the other mobile–satellite services (the provisions of Resolution 222 (WRC-2000) shall apply).     (WRC-2000)

    354 The use of the bands 1 525–1 559 MHz and 1 626.5–1 660.5 MHz by the mobile–satellite services is subject to coordination under No. 9.11A.

    355 Additional allocation:  in Bahrain, Bangladesh, Congo (Rep. of the), Djibouti, Egypt, Eritrea, Iraq, Israel, Kuwait, Qatar, Syrian Arab Republic, Somalia, Sudan, South Sudan, Chad, Togo and Yemen, the bands 1 540–1 559 MHz, 1 610–1 645.5 MHz and 1 646.5–1 660 MHz are also allocated to the fixed service on a secondary basis.     (WRC-12)

    356 The use of the band 1 544–1 545 MHz by the mobile–satellite service (space-to-Earth) is limited to distress and safety communications (see Article 31).

    357 Transmissions in the band 1 545–1 555 MHz from terrestrial aeronautical stations directly to aircraft stations, or between aircraft stations, in the aeronautical mobile (R) service are also authorised when such transmissions are used to extend or supplement the satellite-to-aircraft links.

    357A In applying the procedures of Section II of Article 9 to the mobile–satellite service in the frequency bands 1 545–1 555 MHz and 1 646.5–1 656.5 MHz, priority shall be given to accommodating the spectrum requirements of the aeronautical mobile–satellite (R) service providing transmission of messages with priority 1 to 6 in Article 44. Aeronautical mobile–satellite (R) service communications with priority 1 to 6 in Article 44 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 (the provisions of Resolution 222 (WRC-12) shall apply).     (WRC-12)

People's Rep. of Korea, Romania, Tajikistan, Tunisia, Turkmenistan and Ukraine, the frequency bands 1 550–1 559 MHz, 1 610–1 645.5 MHz and 1 646.5–1 660 MHz are also allocated to the fixed service on a primary basis. Administrations are urged to make all 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
