in No. 337 operating in the aeronautical radionavigation service, or radar systems in the maritime radionavigation service operating in this band on a primary basis in the countries listed in No. 471.     (WRC-07)

    474 In the band 9 200–9 500 MHz, search and rescue transponders (SART) may be used, having due regard to the appropriate ITU‑R Recommendation (see also Article 31).

    474A The use of the frequency band 9 200–9 300 MHz and 9 900–10 400 MHz by the Earth exploration–satellite service (active) is limited to systems requiring necessary bandwidth greater than 600 MHz that cannot be fully accommodated within the frequency band 9 300–9 900 MHz. Such use is subject to agreement to be obtained under No. 9.21 from Algeria, Saudi Arabia, Bahrain, Egypt, Indonesia, Iran (Islamic Republic of), Lebanon and Tunisia. An administration that has not replied under No. 9.52 is considered as not having agreed to the coordination request. In this case, the notifying administration of the satellite system operating in the Earth exploration–satellite service (active) may request the assistance of the Bureau under Sub-Section IID of Article 9.     (WRC-15)

    474B Stations operating in the Earth exploration–satellite (active) service shall comply with Recommendation ITU-R RS.2066-0.     (WRC-15)

    474C Stations operating in the Earth exploration–satellite (active) service shall comply with Recommendation ITU-R RS.2065-0.     (WRC-15)

    474D Stations in the Earth exploration–satellite service (active) shall not cause harmful interference to, or claim protection from, stations of the maritime radionavigation and radiolocation services in the frequency band 9 200–9 300 MHz, the radionavigation and radiolocation services in the frequency band 9 900–10 000 MHz and the radiolocation service in the frequency band 10.0–10.4 GHz.     (WRC-15)

    475 The use of the band 9 300–9 500 MHz by the aeronautical radionavigation service is limited to airborne weather radars and ground-based radars. In addition, ground-based radar beacons in the aeronautical radionavigation service are permitted in the band 9 300–9 320 MHz on condition that harmful interference is not caused to the maritime radionavigation service.     (WRC-07)

    475A The use of the band 9 300–9 500 MHz by the Earth exploration–satellite service (active) and the space research service (active) is limited to systems requiring necessary bandwidth greater than 300 MHz than cannot be fully accommodated within the 9 500–9 800 MHz band.     (WRC-07)

    475B In the band 9 300–9 500 MHz, stations operating in the radiolocation service shall not cause harmful interference to, nor claim protection from, radars operating in the radionavigation service in conformity with the Radio Regulations. Ground-based radars used for meteorological purposes have priority over other radiolocation uses.     (WRC-07)

    476A In the band 9 300–9 800 MHz, stations in the Earth exploration–satellite service (active) and space research service (active) shall not cause harmful interference
