Agenda Item Description
Agenda 1.3 This agenda item refers to bands between 9 and 10 GHz, where requirements have been identified for more spectrum to be available for: i) radiolocation, by raising its status in the 9 200 - 9300 MHz from secondary to primary, to be used in conjunction with existing primary allocations which include the 9 000 - 9 200 MHz and 9 300 - 9 800 MHz bands; ii) EESS, by allocating up to 200 MHz of additional spectrum around a current allocation at 9 500 - 9 800 MHz
Agenda 1.5 This agenda item covers consideration of mobile allocations to be used for wideband aeronautical telemetry and associated telecomand, based upon: i) study of the spectrum requirements for such systems; ii) study of possible upgrading of suitable secondary mobile allocations in the range 3 - 16 GHz to primary, undertaking sharing studies where required; iii) consideration of additional allocations in the range 3 - 16 GHz to the mobile service for such services, undertaking sharing studies where required;
Agenda 1.6 This agenda item relates to aeronautical mobile (R) services in bands between 108 MHz and 6 GHz. It notes there are new requirements to support air navigation, and so the following work is required: i) to identify if existing allocations to aeronautical services are sufficient for these new applications; ii) if additional spectrum is required, to identify what might be suitable bands, taking into account the need to not constrain existing and planned use of such bands, and so undertaking sharing studies where required; iii) in particular, how to accommodate the requirements for aeronautical systems in the band 5 091 - 5 150 MHz iv) to consider what actions would be required to broaden current satellite frequency allocations to support the expansion of the ICAO CNS/ATM system
Agenda 1.13 This agenda item covers issues relating to all services in HF bands between 4 MHz and 10 MHz, excluding those in the band 7 000 - 7 200 kHz and those covered by Appendices 25, 26, and 27. Technological change has made bands allocated for A1A Morse telegraphy and narrow band direct printing under utilised, while there is a demand for new digital technology and more spectrum for broadcast applications. Studies are therefore required to: i) continue to study under Resolution 729 the use of frequency adaptive systems in the MF and HF bands; ii) identify the characteristics of digital system(s) to be used in the MF/HF bands by the maritime mobile service, taking into account MMS requirements and impact on Appendix 17; iii) study the potential to allocate further bands to the broadcast service, taking into account other services using these bands
Agenda 1.14 This agenda item relates to the continued transition to the Global Maritime Distress and Safety System (GMDSS). It covers: i) review of progress towards implementing GMDSS, in particular the continued use of VHF channel 16 and the frequency 2 182 kHz as voice calling channels, taking into account of factors such as decisions by IMO, availability of GMDSS equipped ships, density and classes of ships etc; ii) study into suitable future technology(s) to replace, where considered appropriate, voice calling methods.
Agenda 1.16 This agenda item relates to the identification numbers issued to ships and other maritime related stations (eg coastal stations) called Maritime Mobile Service Identities (MMSIs). It covers the: i) review the Recommendations for assigning MMSIs, and identifying alternative resources if there is a rapid exhaustion of free MMSIs ii) study of the implications and any necessary changes involved in assigning MMSIs to SAR aircraft
Resolution 413 [COM5/2] This resolution relates to the use of the band 108 - 117.975 MHz by aeronautical services, where new applications are being considered. In addition new digital sound broadcasting systems are planned to be introduced in the band 87 - 108 MHz. However no compatibility criteria exist between these two services. Therefore there is the need for further study of any compatibility issues relating to these services and frequency bands.
