COMSAR 16/4/5 was based on the provisional Final Acts - WRC-12 and contained temporary numbers for RR provisions. The updated version of the document contains the definitive provision numbers as they will appear in the Radio Regulations (RR). In addition, information is also added related the suppression of Resolution 342 (Rev. WRC-2000) and the dates of WRC-15 as approved by the ITU Council 2012 (Resolution 1343 contained in Doc. C12/85(Rev.1)). Introduction 1 The World Radiocommunication Conference (WRC-12) was held in Geneva, Switzerland, from 23 January 17 February 2012. The Secretariat participated as an observer from 23 January 3 February 2012.
Page 2 2 The main purpose of WRC-12 was address the worldwide use of radio frequencies and meet the global demand for spectrum, fuelled by rapid technological developments and growth in the information and communication technology (ICT) secr, resulting in an update of the provisions of the ITU Radio Regulations (RR) by which the worldwide use of the complete radio spectrum is regulated. These regulations are of utmost importance the maritime community for the unconditional operation of the GMDSS, the proper operation of navigational equipment (radar, satellite radio navigation, AIS, etc.) including the use of radio frequencies for general communication. 3 The development of the IMO Position on WRC-12 Agenda items concerning matters relating maritime services started during COMSAR 12, in early 2008. Further work was done by the Joint IMO/ITU Experts Group during its meetings in 2008, 2009 and 2010 and by COMSAR 13, COMSAR 14 and COMSAR 15. MSC 85, MSC 86, MSC 87 and MSC 88 had endorsed the progress reported on this matter by the COMSAR Sub-Committee and MSC 89, in May last year, had approved the final text of the IMO position. 4 As requested by COMSAR 15, MSC 89 had authorized the Joint IMO/ITU Experts Group at its meeting in September 2011 add, as appropriate, more non-contentious information in the background sections of the agenda items contained in the IMO position for WRC-12 in order strengthen the arguments supporting the IMO position. Following the instructions of MSC 89, the Expert Group had agreed on amendments the Background sections of Agenda items 1.9 and 8.2 (COMSAR 16/4). As further instructed by MSC 89, the Secretariat had submitted the IMO position ITU. The IMO position was made available as WRC-12 document 20. 5 The Conference was attended by more than 3,500 delegates and in tal more than 2,000 proposals were submitted under 33 substantial agenda items. The agenda for WRC-12 was developed at WRC-07 and included 15 agenda items related the maritime services. A brief description of the five most important items is given below. The importance of the L-band for the maritime mobile-satellite service 6 Under agenda item 1.7, the Conference considered the long-term spectrum availability and access spectrum necessary meet requirements for the aeronautical mobile-satellite (R) service. Studies carried out on existing allocations for mobile satellite services had concentrated on the so-called L-band, in which the maritime service has also a great interest. IMO had informed the Conference that the L-band was currently already heavily used by the maritime mobile-satellite service for safety of life radiocommunication and increased usage was anticipated, taking in account that additional operars might be allowed provide GMDSS services in the near future. 7 The outcome of WRC-12 resulted in "no change" the existing allocation and regulary and operational provisions of the designated bands 1 530-1 544 MHz (space--earth) and 1 626.5-1 645.5 MHz (Earth--space) available for distress and safety purposes in the maritime mobile-satellite service as well as for routine non-safety purposes, in which bands GMDSS distress, urgency and safety communications have priority (in particular No. 5.353A and Table 15-2 of Appendix 15). 8 To detail coordination meeting procedures, the Conference revised Resolution 222 (Rev. WRC-12) on the use of the bands 1 525-1 559 MHz and 1 626.5-1 660.5 MHz by the mobile-satellite service, and procedures ensure long-term spectrum access for the aeronautical mobile-satellite (R) service, as set out in annex 5.
Page 3 New digital technologies for the maritime mobile service in the high- bands 9 Under agenda item 1.9, the Conference considered a revision of frequencies and channelling arrangements of Appendix 17 the Radio Regulations in order implement new digital technologies for the maritime mobile service. IMO had informed the Conference that there was significant interest in the use of the high- bands by shipping. More than 4,500 ships were known use already digital systems, which aumatically route messages their destination, producing a million messages a month. New, highly efficient technology were being developed which in the next three years or so were expected double this use. IMO's view on agenda item 1.9 was that the frequencies currently allocated for use by the GMDSS need be retained because at this time IMO had no intention of changing the requirements for narrow-band direct-printing and digital selective calling. The major portion of the Appendix 17 bands would, however, become available for new digital technologies for the maritime mobile service. Furthermore, it was IMO's view that the bands allocated for Morse should remain available for use by the maritime community, without the need claim protection. 10 The Conference revised the frequencies and channelling arrangements of Appendix 17 the Radio Regulations, as set out in annex 2. Operation of safety systems for ships and ports 11 Agenda item 1.10 addressed the maritime communication requirements support safety systems for ships and port operations in the global context of trying ensure the safe and efficient operation of global shipping. In addressing agenda item 1.10, work had focused on the harmonization of maritime spectrum in the following four primary areas:.1 protection in the Radio Regulations for the spectrum used by AIS, because the two frequencies currently available are used ensure navigational safety, vessel traffic management in congested ports, and vessel tracking;.2 allocation of two additional AIS frequencies for improved satellite detection and tracking of vessels, enhance maritime safety and security;.3 harmonization of the maritime mobile service in the band 415 khz 526.5 khz for enhanced data rate transmissions for maritime safety information, future e-navigation applications, and security broadcasts; and.4 harmonization under Appendix 18 of the Radio Regulations (156 MHz 162 MHz) of a band for VHF digital services, using advanced data transmission techniques for enhanced port operations, and additional simplex channels from existing duplex channel pairs. With regard the harmonization of Appendix 18, IMO further informed the Conference that it supported further joint IMO/ITU-R studies wards identification of a channel or channels for future applications, including man overboard (MOB) equipment. 12 With reference paragraph 11.1 above, the protection in the Radio Regulations for the spectrum used by AIS has been achieved by changes Article 5 of the Radio Regulations. Unfortunately, there was no agreement on this matter and the regulary
Page 4 protection for the two frequencies currently available for AIS is different for all three ITU regions, as set out in annex 1, pages 4 and 5. 13 With reference paragraph 11.2 above, there was worldwide support for an allocation the mobile satellite service (Earth--space) relating the frequencies of Channel 75 and 76 of Appendix 18. After a long debate, it was decided that this allocation was made on a primary basis for Region 2 and on a secondary basis for Regions 1 and 3. Appendix 18 and Article 5 were modified reflect this new allocation, as set out in annex 1, pages 4 and 5. 14 With reference paragraph 11.3 above, the Conference agreed on the harmonization of the maritime mobile service in the band 415 khz 526.5 khz, resulting in an exclusive worldwide allocation for the maritime mobile service in the band 495-505 khz and a co-primary allocation in the band 510-525 khz in Region 2, as set out in annex 1, page 3. 15 With reference paragraph 11.4 above, the Conference agreed on a revision of Appendix 18 of the Radio Regulations. It designated two bands inside Appendix 18 for digital emissions; 2x300 khz in Regions 1 and 3 as from 1.01.2017; and 2x125 khz in Region 2 as from 1.01.2013, with some country variations, as set out in annex 2. It should be noted that one (160.900 MHz) is reserved for experimental use for future applications or systems (e.g. new AIS applications, man over board systems, etc.) and that four channels have been identified which may be used for possible testing of future AIS applications. New maritime mobile systems be implemented in the 500 khz band 16 Under agenda item 1.23, the Conference considered an allocation of about 15 khz in parts of the band 415-526.5 khz the amateur service on a secondary basis. IMO had informed the Conference that it had critical systems operating in this range and was developing new requirements (1) for the promulgation of additional security-related information, (2) for the implementation of e-navigation and (3) in reviewing the elements and procedures of the GMDSS IMO had expressed its concern that, based on existing studies, a secondary allocation for the amateur service would cause harmful interference existing and future systems and recommended that this allocation was not made. 17 After extensive debate, the Conference allocated 7 khz (the band 47-479 khz) the amateur service on a secondary basis, except 26 countries of Region 1 and one country of Region 3 listed in the provision 5.B123, as set out in annex 1, pages 1 and 2. In addition, the aeronautical radionavigation service was upgraded a primary status in some countries in the band 435-495 khz, listed in the provision No.5.77. Future requirements 18 A provisional agenda for WRC-15 was developed under Agenda item 8.2, as set out at annex 16. In general, identify any threats spectrum currently in use by maritime services, it is important monir closely what is happening in the development of proposals for almost all WRC agenda items. There are several items on the agenda for WRC-15 of relevance the maritime service, inter alia:.1 review the provisions relating earth stations located on board vessels (ESVs), based on studies conducted in accordance with Resolution 909 (WRC-12) (agenda item 1.8);
