1 6th annual ARTES Applications Workshop - April 2016

2 Contractual Background Advanced Ship Tracking and Reporting (A-STAR) is a cofunded ESA ARTES 21 2C SAT-AIS applications demonstration project, which runs October 2014 to June 2016 Consortium comprises: - exactearth Europe / Gatehouse / Roke Manor Research / National Space Centre Ireland / TeamSurv Objective is to: - under the ESA-EMSA SAT-AIS Initiative supply ee SAT-AIS data to EMSA, including ee Doppler data - Develop and trial Positional Anomaly (PA) services - Develop and trial Behaviour Analysis (BA) services, courtesy of Roke - Ingest global sea-state and weather forecast data for event generation, courtesy of TeamSurv Slide 2

3 A-STAR Demonstration End Users European Maritime Safety Agency (EMSA): - under the ESA-EMSA SAT-AIS Initiative A-STAR continues to supply SAT-AIS data to EMSA for use in its SAT-AIS demonstration service roll out to EC member states Defence Centre for Operational Oceanography (FCOO) Danish Maritime Authority (DMA) Irish Navy UK National Maritime Intelligence Centre (NMIC) Each of these: - provides input into the services specifications (i.e. user requirements) - uses the implemented pre-operational services, evaluates and provides feedback Slide 3

4 Positional Anomaly Service Of the 130,000+ AIS enabled vessels, < 2% are misrepresenting their location. Being able to quickly identify those vessels that represent a security or commercial threat can significantly improve operational efficiency, and enhance national security. Slide 4

5 Positional Anomaly Service - exactearth s Positional Anomaly Service identifies vessels globally that have discrepancies with their reported positions - vessels attempting to hide their true position by either simply entering false positions into their AIS transponder, or by disconnecting their GPS - Vessels accidentally reporting incorrect or no positions - Positional Anomaly Service reports: - 181/91 longitude/latitude coordinate transmissions (these occur when the GPS attached to the AIS receiver is not connected or not functioning) - reported positions out of satellite footprint (i.e. the ship is reporting a position that cannot be correct given the fact the transmission was detected within a particular satellite acquisition coverage area) - hard-coded/fixed positions (e.g. identical GPS locations even though vessel is transmitting > 1 kn velocity) Slide 5

6 Positional Anomaly Service - Approximate position calculation via satellite footprint triangulation - Estimated position reporting via Doppler frequency shift calculation - This service is available to provide information on: - Vessels with a history of anomalous or suspicious position reports - Vessels that falsely report to be within an organisation s Area of Interest (AOI) - Vessels that are likely to be within an organisation s AOI but are reporting to be elsewhere in the world - Positional Anomaly Service made available via: - ee s OGC-compliant web feature/map server - ee s interactive web viewer ShipView - GH s interactive web viewer aisweb - PDF reports Slide 6

7 As it turns out, all vessels in the middle of Africa are not invalid. This vessel (MMSI ), shows up as continually fishing inland around Nigeria and Chad. Using PA we can establish that the vessel is actually fishing off the coast of Namibia.

8 Positional Anomaly Service PA Estimates Comparing the actual to expected AIS Signal RF characteristics, able to generate independent estimates for vessel location Slide 8

9 Slide 9 PA Service via Gatehouse aisweb

10 Behaviour Analysis Service Highlights the most unusual behaviour Reduces operator workload to allow them to focus on the most unusual behaviour Current focus is on identifying illegal fishing - Vessels acting like a fishing vessel which are not reported as fishing vessels - Vessels marked as fishing appearing in inconsistent locations Slide 10

11 Behaviour Analysis Service Detects presence of the abnormal System learns what is normal Builds a picture of what to expect - Actual and Relative Position - Speed - Grouping Slide 11

12 Behaviour Analysis Service Reduces operator workload, and highlights activities of interest Guides the operator Interfaces with exiting sensor systems Can be used on various data sources - Satellite AIS - Terrestrial AIS - Radar - Video Slide 12
