Benefits of AIS Space

  • Global Coverage = GLOBAL
  • Ability to validate position information

– Course and speed within AIS message – Window of ± 15 minutes allows numerous AIS detections per ship - abnormal behavior apparent. – Backtrack stream of position reports of suspected vessels through point of incident. – Ideal information to assist prosecution - difficult to spoof - other periodic reporting sources lack the ability to validate, and have insufficient information to show deviation of course or speed to avoid detection.

Benefits of AIS Space

  • Complementary to LRIT
  • Future possibility to use information for composing

message parts into the LRIT system.

  • Single automatic ship source for Long Range

Reporting

– Working in parallel with Ship monitoring services such as SafeSeaNet and Port information Systems - able fuse AIS space information with more detailed Port, Cargo and passenger details.

  • Work needed here to allow competent authority accesss

to global port network.

  • Single port window needed. Even better would be

Single national window.

Monitoring AIS signals from space

  • Global coverage
  • With Polar Orbiting Spacecraft – every

pass provides Northern and Southern Hemisphere coverage

  • We need constellation that can provide

frequent updates with high probability

  • f detection and real time vessel

localization.

  • Space Based Data can be merged and

correlated with Ground Based AIS and Other Systems

  • Data collection can be encrypted
  • AIS deception attempts readily

detected from space

  • Inter-governmental Agency Co-
  • peration?

– Highly desirable

Why it is hard to do from Space

  • AIS signals, when seen

from space encompass many AIS cells

  • These messages can

“collide” at the spacecraft resulting in messages being lost or garbled

  • De-collision algorithms

will cope for now.

  • Prudent to think about

third frequency for 2011 (WRC)

Typical satellite field

  • f view

Many SOTDMA cells

Long Range Applications

  • Maritime Applications

– LRR including (LRIT) and mandatory safety reports

  • More Than 64 mandatory and voluntary reports

– Requirement to report incidents, Ice, storms pollution, Piracy, Alien smugling – ISPS - Ship Security Alert – Maritime Safety Information Broadcasts (NAVTEX) – Fishing Vessel Monitoring System (VMS)

  • Mandatory and Voluntary LRR message could be replaced by LRIT

information plus an additional message part that was either manually or preferably automatically generated when on board sensors measure tendency towards degradation of seaworthiness.

  • Static and dynamic parameters.
  • Marine Electronic Highways will require offshore surveillance.

Enabler to Evolution of Long Range Reporting

  • AIS Satellite combined with LEO or

MEO Low data rate communication services.

  • To provide a complete suite of Maritime

communications for:-

– Global maritime Distress Service System (GMDSS) – Long Range Identification and Tracking (LRIT - IMO) – Vessel monitoring Systems (Fishery VMS EU & UNFAO) – Traffic Monitoring – Evolution of Long Range reporting to suite Environmental issues – GMDSS Area 4 - Polar Areas

The Future and next steps

  • If we consider AIS from space as a likely

future candidate to provide all ship reporting ID, position and status information needs.

– Then should we have new AIS messages?

– LRR, VMS, Degradation of seaworthiness?

– If so for which applications? – Do we want AIS SARTS to be detected from space and what about AIS EPIRBS? – Considering the certain expansion of AIS population What frequency and messages do we need?

Can AIS or LRIT be spoofed

– VMS experience

– There are some ±24,000 vessels fitted with VMS equipment (±11500 in Europe). – Existing VMS systems require vessels to report positions hourly, or if able to be polled, once every two hours.

– Falsification of VMS Position Reports.

  • Cases of Vessels reporting false position information

– Major hindrance to monitoring compliance and providing evidence of infringements

– LRIT - Falsification of LRR or LRIT message parts?? – Which is more robust - AIS Space or Commercial Communications?

AIS Provides its own PVT solution

If LRIT or LRR information is spoofed, will this have consequence on regulatory use of the information?
