  1. The shore based AIS Service as an e-navigation service Principle engineer Tom BrauteNorwegian Coastal Administration NNF E-navigation Conference – Oslo, October 16th – 17th 2007 NNF E-navigation Conference Oslo, October 16th – 17th 2007

  2. The Norwegian Coastal Administration AIS service Layered structure: • AIS Service Management • Logical Shore Station • Physical Shore Station 36 AIS Physical Shore Stations External Basic AIS Services NNF E-navigation Conference Oslo, October 16th – 17th 2007

  3. External Basic AIS Services -examples • Receive data from AIS mobile stations • Transmit safety related messages • Transmit DGNSS corrections • Transmit binary messages • Transmit synthetic/virtual AtoN data • Transmit assignment command NNF E-navigation Conference Oslo, October 16th – 17th 2007

  4. Use of received AIS data Examples • AISOnline (WEB presentation tool) • VTS; in combination with other shore-based ENAV services • Radar • VHF • LRIT... NNF E-navigation Conference Oslo, October 16th – 17th 2007

  5. Use of AIS Binary Messages(MET/HYD data application) NNF E-navigation Conference Oslo, October 16th – 17th 2007

  6. Use of DGNSS Corrections GNSS AIS GNSS DGNSS corrections Base Station Onboard Equipment VESSEL DGNSS Service Shore based AIS Service LAND NNF E-navigation Conference Oslo, October 16th – 17th 2007

  7. NB! Demonstration only. IEC standard for presentation of navigation information (IEC 62288) requires AIS AtoNs to be displayed by a diamond symbol. Virtual AtoN Example: • Need to mark temporary danger • Possible solution: Virtual special mark NNF E-navigation Conference Oslo, October 16th – 17th 2007

  8. AIS VDL Shore based AIS Service Applica-tion 1 Applica-tion 2 Applica-tion 3 Applica-tion 4 DataTrans-fer Net-work Link Application-to- application virtual connection(peer-to-peer) eNAV- service Concept of ENAV service Point of view from shore applications Encapsulation of complexity for shore applications NNF E-navigation Conference Oslo, October 16th – 17th 2007

  9. Add value to raw data Interfacing ENAV system to physical links MMI to primary users (single service) Data exchange shore-to-shore Functional interface = External Basic AIS Services ENAV System Architecture Shore based AIS Service NNF E-navigation Conference Oslo, October 16th – 17th 2007

  10. Definition of e-navigation(IMO WG on ENAV) • “E-Navigation is the harmonized collection, integration, exchange, presentation and analysis of maritime information onboard and ashore by electronic means to enhance berth to berth navigation and related services, for safety and security at sea and protection of the marine environment.” NNF E-navigation Conference Oslo, October 16th – 17th 2007

  11. Limitations of AIS as an ENAV service • Limited link capabilities • Safety issues • Limited shipborne equipment capabilities • Display of virtual/syntetic AtoNs • Display of binary application data • Use of DGNSS corrections NNF E-navigation Conference Oslo, October 16th – 17th 2007

  12. Authenticity? Confidentiality? Integrity? AIS link capabilities Authenticity Confidentiality Integrity Traffic data Aids to Navigation Maritime Safety Info Met/Hyd/Oce service Ship Reporting ... Shore e-Nav System Ship e-Nav System Availability Transparency AIS LINK NNF E-navigation Conference Oslo, October 16th – 17th 2007

  13. Safety issues !! Main function of AIS is anti-collision !! • AIS Services requires capacity on the VDL • Management of the VDL capacity is needed to protect the main functions of AIS NNF E-navigation Conference Oslo, October 16th – 17th 2007

  14. Questions? NNF E-navigation Conference Oslo, October 16th – 17th 2007
