JCG GMDSS Symposium VDES: Next Generation AIS in the Review & Modernization of the GMDSS 19 November 2013
VDES: Next Generation AIS Contents 1. Present situation & Problems GMDSS & AIS 2. Future: from now on 3. Wrap up Review and modernization of the GMDSS & VDES : Next Generation AIS 1
1. Present situation & Problems GMDSS & AIS
1. Present situation & Problems GMDSS
GMDSS:Function, Carriage requirements Automatic/Manual Distress Alerting and Locating DISTRESS Button SOLAS Chapter IV Carriage requirements All cargo ships of 300GT or upwards engaged on international voyages All passenger ships engaged on international voyages 4
GMDSS: Components MF/HF/VHF Radio with DSC Handheld VHF/UHF Radio Inmarsat system with EGC NBDP terminal NAVTEX SART EPIRB, etc 5
GMDSS: History 1912 Titanic 1914 SOLAS Convention 1974 SOLAS Amendments Introduction of the GMDSS 1999 GMDSS fully enforced Abolished Morse Keying 6
GMDSS: Problems Old fashioned (70 s) Many components Complicated Cost for running shore base stations Poor coverage in Polar Region Non-SOLAS ships 7
1. Present situation & Problems AIS
AIS:Function 1 Automatic Exchange of Ships information Ships ID/Type/Position/Course/ Speed (SOG, ROT, ), Navigational Status, etc. 9
AIS:Function 2 Exchange of ASM: Application Specific Messages VTS related data, Meteorological and Hydrographic data, Short text message, etc. 10
AIS: Mechanism VDL (VHF Data Link) on CH AIS1, AIS2 TDMA, 2250slot/sec Coverage: 20.. 30 NM 11
AIS:Carriage requirements SOLAS Chapter V Carriage requirements All ships of 300GT and upwards engaged on international voyages All cargo ships of 500GT and upwards not engaged on international voyages All passenger ships irrespective of size 12
AIS:Carriage requirements SOLAS Chapter V Carriage requirements All ships of 300GT and upwards engaged on international voyages All cargo ships of 500GT and upwards not engaged on international voyages All passenger ships irrespective of size 13
AIS: History 1998 Adoption PS for AIS 2002 SOLAS Amendments (MSC 73) Introduction of the AIS 2008 AIS fully enforced (July 1st) 14
AIS:Station Types Class A AIS Class B AIS AIS-SART AtoN (Aids to Navigation) AIS AIS-MOB EPIRB-AIS Base Station Repeater Station 15
AIS: Problems Non-SOLAS Ships Variety of devices Needs to exchange more ASM Needs for extension of coverage Congestion of AIS Channel (AIS1, AIS2) IMO concentration only on Class A 16
AIS and GMDSS AIS is NOT a part of GMDSS Coverage of the carriage requirements are NOT same 17
2. Future: from now on Review and Modernization of the GMDSS & VDES: Next Generation AIS

IMO Review and Modernization of the GMDSS 12 NEW ITEM might be included (candidate list) 2013 IMO COMSAR17 1. AIS (Traditional AIS) 2. HF e-mail and data systems 3. VHF data systems 4. ASM (Application Specific Messages) over AIS or VHF data systems 5. NAVDAT 6. Modern satellite communication technologies 21
IMO Review and Modernization of the GMDSS 12 NEW ITEM might be included (candidate list) 2013 IMO COMSAR17 7. Additional GMDSS satellite service providers 8. Hand-held satellite telephones in survival craft 9. Hand-held VHF with DSC and GNSS for survival craft 10. Man Overboard Devices 11. Cospas-Sarsat MEOSAR system; and 12. AIS and GNSS-equipped EPIRB. 22
2. Future: from now on VDES: Next generation AIS
VDES: Next generation AIS (IALA e-nav WG3+4) VDES formula AIS (Traditional AIS) + ASM(Application Specific Messages) + VDL (VHF Data Link) + SAT (Satellite Link) = VDES :VHF Data Exchange System 24
VDES: : Figure TOKYO of WORKSHOP VDES (IALA e-nav 2012/12/3-7 WG3+4) 25
VDES: Development plan (IALA e-nav WG3+4) 2012 WRC-12 VDES testing frequency allocation 2013 Development of draft ITU-R Rec. M.[VDES] 2014 Development of prototype and testing 2015 WRC-15 VDES exclusive frequency allocation 2015 VDES Sat launch 2016 VDES Sat running & testing 2017 Start implementation of the Modernized GMDSS 26
3. Wrap up
VDES: Next Generation AIS in the Review & Modernization of the GMDSS Might be a part of the Modernized GMDSS Milestone: 2017 Just started studying in detail 28
