  1. Agenda item 1.10 – Allocation requirements of safety systems of ships and ports Presenter: Peter Pokorny

  2. Agenda item 1.10 Allocation requirements of safety systems of ships and ports to examine the frequency allocation requirements with regard to operation of safety systems for ships and ports and associated regulatory provisions, in accordance with Resolution 357 (WRC-07).

  3. Agenda Item 1.10 Issue A - to upgrade the regulatory status of AIS 1 to reflect its importance to safety of navigation; Issue B - to provide additional channels to enhance the satellite detection of larger vessels via AIS; Issue C – to re-allocate the band 495-505 kHz (all Regions) for exclusive maritime mobile use (plus 505-510 kHz in Region 2) for data transmissions from ports to ships, to support safety and security, and for future e-Navigation; and Issue D - to create additional single-frequency VHF channels to reduce channel congestion, to provide additional provisions for VHF data transmissions, and to consider a channel for man overboard devices. 1 Automatic Identification System

  4. ITU-R Regional PositionsAgenda Item 1.10 2 2 Variations to Regional positions by some administrations are not shown above.

  5. Issue A – Status of ‘AIS 1’ and ‘AIS 2’ Outcome A uniform outcome was not possible between all ITU Regions, but a good result for Region 3. Extract from Article 5, Section IV, Table of Frequency Allocations (WRC-12 Provisional Final Acts)

  6. Issue A – Status of ‘AIS 1’ and ‘AIS 2’(cont’d) Outcome (cont’d) In Region 2, under new footnote 5.D110, until 1 January 2025 AIS 1 and AIS 2 may be used by the fixed and mobile services on a primary basis, but after that, the allocations will no longer be valid. Prior to 1 January 2025, administrations are encouraged to discontinue fixed and mobile service use and the maritime mobile service will have priority over fixed and mobile services.

  7. Issue B – Satellite AIS Outcome VHF Appendix 18 channels 75 and 76 approved for satellite AIS (Earth-to-space)3 on secondary basis in Regions 1 and 3, with co-primary status in Region 2. 3 These channels can still be used for navigation communications limited to 1 watt, but the long-range broadcast AIS transmissions (Message 27 in Rec. ITU-R M.1371) can be 12.5 watts (once/3 min on each channel when out of range of terrestrial AIS base stations (refer footnote RR 5.G110 and Note n) in Appendix 18). Extract from Article 5, Section IV, Table of Frequency Allocations (WRC-12 Provisional Final Acts)

  8. Issue C – Broadcasts of safety and security information for ships and ports Outcome Global exclusive allocation on a primary basis to the maritime mobile service (MMS) from 495-505 kHz, and for 505-510 kHz on a co-primary basis in Region 2.The footnotes 5.82A and 5.82B in the 495-505 kHz band have been suppressed. Extract from Article 5, Section IV, Table of Frequency Allocations (WRC-12 Provisional Final Acts)

  9. Issue D – Appendix 18Outcome - The ‘new digital bands’ two new digital bands (for digitally modulated emissions), are to be introduced, as described in the most recent version of Recommendation ITU-R M.1842, see new Notes B1) and C1) of up to 300 kHz (from 1 January 2017) as follows (based on channel centre frequencies):

  10. Existing Appendix 18 (WRC-07)

  11. Proposals for Appendix 18 Source: ITU-R WRC-12 CPM-2 Report, and Chair,1.10 Drafting Group (SWG 4C2 a.i. 1.10), WRC-12

  12. Issue D – Appendix 18Outcome - The ‘new digital bands’ (cont’d) Regions 1 and 3: (2 x 300 kHz) Channels 80, 21, 81, 22, 82, 23, 83, 24, 84, 25, 85, 26 and 86, see new Note B1) – but they can still be used for analogue communications subject to not claiming protection from digitally modulated emissions, see new Note B1). Region 2: (2 x 125 kHz) channels 24, 84, 25, 85, 26 and 86, see new Note C1). These six channels were the only channels available in the United States.

  13. Issue D – Appendix 18Outcome - The ‘new digital bands’ (cont’d) Regional variations in the digital bands: In the Southern African Developing Community (15 countries): (2 x 200 kHz) channels 82, 23, 83, 24, 84, 25, 85, 26 and 86, see new Note D1). In China: (2 x 175 kHz) channels 23, 83, 24, 84, 25, 85, 26 and 86, see new Note D1) also.

  14. Issue D – Appendix 18Outcome - The ‘new digital bands’ (cont’d) Regional variations in the digital bands (cont’d): Until 1 January 2017, in Regions 1 and 3, the existing duplex channels 78, 19, 79 and 20 can continue to be assigned. From that date, these channels shall only be assigned as single-frequency channels. However, existing duplex assignments may be preserved for coast stations and retained for vessels, subject to coordination with affected administrations, see new Note A1).

  15. Issue D – Appendix 18Outcome - The ‘new digital bands’ (cont’d) Regional variations in the digital bands (cont’d): In Region 2, channels 78, 19, 79 and 20 may be operated as single-frequency channels, subject to coordination with affected administrations, see new Note A2), but they continue to be used in the Netherlands (in Region 1) after 1 January 2017, see new Note A3).

  16. Issue D – Appendix 18Outcome - Conversion of duplex to simplex channels (total of up to 21 new channels) (cont’d): 4- digit channel numbering In Recommendation ITU-R M.1084, where two-frequency channels are operated in single-frequency mode, four-digit numbering is used. If the single-frequency is the ship station tx frequency, a ’10’ is added in front of the Appendix 18 channel number, e.g. 1078. If the single-frequency is the coast station tx frequency, a ’20’ is added in front of the Appendix 18 channel number, e.g. 2078.

  17. Issue D – Appendix 18Outcome – new Note XXX) for 160.900 MHz XXX) In the maritime mobile service, this frequency is reserved for experimental use for future applications or systems (e.g. new AIS applications, man over board systems, etc.). If authorized by administrations for experimental use, the operation shall not cause harmful interference to, or claim protection from, stations operating in the fixed and mobile services.

  18. Issue D – Appendix 18Outcome – new Note YYY) for channels 27, 87, 28 and 88 Duplex channels 27 and 28, and simplex channels 87 and 88 via Note YYY) have been reserved as follows: YYY) These channels may be used for possible testing of future AIS applications without causing harmful interference to, or claiming protection from, existing applications and stations operating in the fixed and mobile services.

  19. Appendix 18 (WRC-12)Summary of Note changes

  20. Article 5Summary of footnote changes resulting from Agenda Item 1.10

  21. Corrections(under Rules of Procedure) An error from the WRC-07 version of Appendix 18 has been corrected: (Table of transmitting frequencies in the VHF maritime mobile band). An ‘x’ has been inserted in the ‘Single frequency’ column against channels 60, 01, 66 and 07. Resolution 357 (WRC-07) has been suppressed. and Finally, Resolution 357 (WRC-07) has been suppressed.
