3 KSAT the Company World Leading Commercial Satellite Centre for: Launch Support Satellite In-Orbit Support Data Acquisition and Processing Satellite based Marine Services

4 KSAT owner structure Kongsberg Defense and Aerospace Norwegian Space Center 100 % 50 % 50 % Kongsberg Spacetec Kongsberg Satellite Services Tromsø Station (TSS) SvalSat (Svalbard) Grimstad Station TrollSat (Antarctica) Ground Station Services Earth Observation

5 KSAT Satellite Centers - Pole to Pole SvalSat, 78 N 14 of 14 orbits Tromsø Station, 69 N, 10 of 14 orbits Grimstad, 58 N 8 of 14 orbits TrollSat/Antarctica, 72 S 12 of 14 orbits

6 Maritime Surveillance Service Chain External/supporting info: Wind, GIS, etc. User Information Service KSAT EO Ship Information Detection Service Radar Operational resource utilisation Satellite tasking Data reception & processing VAP & QA AIS Satellite operator Service Ship information service report VMS Early Warning Alert Requests & Confirmation Distribution Sales & Marketing Service Development ---- Order desk Planning & Feedback Operations centre

7 Vessel Detection System KSAT (1) Two systems in use today: MEOS (KSPT implementation of FFI algorithm) SUMO (JRC developed, integrated in service chain) VDS is in a demonstration/pilot phase at KSAT: No operational day-to-day use(rs) yet, campaigns and demonstrations within projects so far Data from KSAT used for operational VDS by the Norwegian defence VDS is produced and included as a layer for the oil spill monitoring service users Market development is ongoing, world-wide interest

8 KSAT (2) Two satellite systems in use today: Radarsat-1 Envisat ASAR Future satellite systems: Radarsat-2 (TerraSAR-X) Potential future satellite systems: Cosmo/Skymed Sentinel-1 Radarsat-C

11 KSAT Vessel detection development activities SkipSat Algorithm development Norwegian Research Council funded development project SatOcean Ship Service chain and national user development Norwegian Space Centre funded development project MARISS - Maritime security service development, user focussed ESA funded project (GSE) LIMES Maritime security service development, service chain development and user development EC 6th Framework Integrated Project (KO next week) MarNIS Maritime traffic and reporting EC funded project

12 SkipSat Norwegian partners FFI, NPI, Norut IT, Kongsberg Spacetec Development of new and existing algorithms and methods Detection based on coherence and intensity Detection based on superresolution techniques Integration of x-band data (new sensors/satellites) Iceberg and vessel discrimination Tracking of vessels and icebergs (based on coming satellite constellations) Implementation and operationalisation New and improved algorithms integrated in the operational service chain (MEOS system) Validation of operational performance

13 Icebergs Requirements Detection - dimensions Tracking - Where will it go, and what damage will it do? Current Status: Can detect some icebergs, but not calculate size For wide-swath data Easily detected in far range but not in near range Better detection in calm waters (wind shadow, South of FJL)

14 Statoil Project: Franz Josef Land 2004 HH polarization Bright is near KONGSBERG KONGSBERG 26 August 2003

15 Example: Franz Josef Land 2006 Envisat AP Images Acquired on 15th August at: 09:30 UTC (left) 16:08 UTC (right) Icebergs are detected using the ship detection software

16 Objection Detection Software: Franz Josef Land 2006 Detected icebergs around Franz Josef Land app_ _ Latitude Repeat ice band detection app_ _ app_ _ app_ _ app_ _ app_ _ app_ _ app_ _ Possible island Longitude

17 Repeat Detection Ice band detected in consecutive scenes in the cross-pol band of AP data 12th August th August 2006

18 Ice object detection, West Greenland Over 500 objects detected

19 Conclusions Iceberg Detection Possible, but dependent on environmental conditions Limiting factor: spatial resolution Iceberg Tracking Limited by size of icebergs in Barents Sea Worth investigating methods can be applied to ice floes - Possible requirement for ship navigation ice velocity

20 Coherence method (1) Using the coherence improves the target to sea ratio substantially utilising the SLC data, not the detected products as usual today in most systems

21 Coherence method (2)

22 Future SAR systems RADARSAT-2, ALOS, TerraSAR-X, Cosmo-Skymed, Sentinel-1, Radarsat Constellation, Higher resolution Polarimetry Other frequencies Continued development of detection systems needed Increased capabilities come at the expense of reduced swath width Wide area surveillance is often not helped More satellites imply higher revisit frequency But at higher cost Improved revisit increases potential for tracking of vessels/icebergs Improved detection performance can be expected

23 Use of vessel and iceberg detection Fisheries control Monitor and detect illegal fishing Maritime security Illegal trafficking of people and goods Illegal transhipments Recognised Maritime Picture Maritime navigation Navigation in icy waters Maritime traffic monitoring, VTS, traffic separation lanes
