Notes to whole band 5.197A
Part of RSUP RSUP-P/22
Service Aeronautical radionavigation
Category of assignment Primary
Non-civil utilisation Equal rights
Civil utilisation Equal rights
Application ILS
Section 108 – 112 MHz
Additional information Localizers of instrument landing system (ILS-LLZ) with system link to the band 328.6–335.4 MHz (ILS-GP) and to the band 960–1215 MHz (DME).
Future It can be expected that with development of satellite navigation systems, also integration of other navigation systems as it is, e.g. GBAS and for data transfer VDL will progress in the bands of aeronautical radionavigation.
Application VOR
Additional information Navigational VHF omnidirectional radio beacons VOR with system link to the band 960–1215 MHz (DME).
Future Gradual phase-out of VOR equipment utilisation is expected after global navigation system GALILEO will come into operation. It can be expected that with development of satellite navigation systems, also integration of other navigation systems as it is, e.g. GBAS and for data transfer VDL will progress in the bands of aeronautical radionavigation.
Additional information Sharing with non-civil use.
Application Defence systems
Additional information Non-civil use on an equal basis.
Application Aeronautical
Additional information The band may be used in accordance with RR footnote 5.197A by the aeronautical mobile (R) service on a primary basis for systems transmitting information in support of the air navigation and surveillance over aeronautical traffic in accordance with recognised international aviation standards. Such use shall be in accordance with Resolution 413 (WRC-12) and shall not cause harmful interference to nor claim protection from stations operating in the aeronautical radionavigation service in accordance with international aeronautical standards.
Future Coordinated European change to the use of the 8.33 kHz channel width in aeronautical voice communication will continue in period until 31 December 2018. After this date the 8.33 kHz channel bandwidth shall be used only.
Application GPR/WPR
