Detail of Frequency Band

Band reserved for non-civil utilisation. If civil utilisation is also stated with priority, the band is being used equally with civil utilisation on the basis of coordination.

Non-civil stations can use the band with subsidiarity to civil ones (which use the band with priority), but must not interfere and do not have rihgt to protection against interference by civil utilisation.

Non-civil stations cannot use the band.

The use of the bands 1 164 – 1 300 MHz, 1 559 – 1 610 MHz and 5 010 – 5 030 MHz by systems and networks in the radionavigation-satellite service for which complete coordination or notification information, as appropriate, is received by the Radiocommunication Bureau of ITU after 1 January 2005 is subject to the application of the provisions of Nos. 9.12, 9.12A and 9.13 of RR. Resolution 610 shall also apply; however, in the case of radionavigation-satellite service (space-to-space) networks and systems, Resolution 610 shall only apply to transmitting space stations. In accordance with No. 5.329A of RR, for systems and networks in the radionavigation-satellite service (space-to-space) in the bands 1 215 – 1 300 MHz and 1 559 – 1 610 MHz, the provisions of Nos. 9.7, 9.12, 9.12A and 9.13 of RR shall only apply with respect to other systems and networks in the radionavigation-satellite service (space-to-space).

In order not to cause harmful interference to the microwave landing system operating above 5 030 MHz, the aggregate power flux-density produced at the Earth’s surface in the frequency band 5 030-5 150 MHz by all the space stations within any radionavigation-satellite service system (space-to-Earth) operating in the frequency band 5 010-5 030 MHz shall not exceed −124.5 dB(W/m²) in a 150 kHz band. In order not to cause harmful interference to the radio astronomy service in the frequency band 4 990-5 000 MHz, radionavigation-satellite service systems operating in the frequency band 5 010-5 030 MHz shall comply with the limits in the frequency band 4 990-5 000 MHz defined in Resolution 741 (Rev.WRC-15).

In the frequency bands 5 000-5 030 MHz and 5 091-5 150 MHz, the aeronautical mobile-satellite (R) service is subject to agreement obtained under No. 9.21. The use of these bands by the aeronautical mobile-satellite (R) service is limited to internationally standardized aeronautical systems.
