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.

Additional allocation: the band 148 – 149.9 MHz is also allocated to the space operation service (Earth-to-space) on a primary basis, subject to agreement obtained under No. 9.21 of RR. The bandwidth of any individual transmission shall not exceed ± 25 kHz.

The use of the band 148 – 149.9 MHz by the mobile-satellite service is subject to coordination under No. 9.11A of RR. The mobile-satellite service shall not constrain the development and use of the fixed, mobile and space operation services in the band 148 – 149.9 MHz. The use of the frequency band 148-149.9 MHz by non-geostationary- satellite systems in the space operation service identified as short-duration mission is not subject to No. 9.11A. (WRC-19)

The use of the bands 137 – 138 MHz, 148 – 150.05 MHz, 399.9 – 400.05 MHz, 400.15 – 401 MHz, 454 – 456 MHz and 459 – 460 MHz by the mobile-satellite service is limited to non-geostationary-satellite systems.

The frequency band 148-149.9MHz in the space operation service (Earth-to-space) may be used by nongeostationary- satellite systems with short-duration missions. Non-geostationary-satellite systems in the space operation service used for a short-duration mission in accordance with Resolution 32 (WRC-19) of the Radio Regulations are not subject to agreement under No. 9.21. At the stage of coordination, the provisions of Nos. 9.17 and 9.18 also apply. In the frequency band 148-149.9MHz, non-geostationary-satellite systems with short-duration missions shall not cause unacceptable interference to, or claim protection from, existing primary services within this frequency band, or impose additional constraints on the space operation and mobile-satellite services. In addition, earth stations in non-geostationary-satellite systems in the space operation service with short-duration missions in the frequency band 148-149.9MHz shall ensure that the power flux-density does not exceed −149 dB(W/(m2
