5 High resolution satellite radar imagery Why using High resolution radar imagery? Not weather dependent (not masked by clouds) Day & night observation capacity Large coverage and high resolution capacity Using satellite high resolution radar imagery, it is possible to: Detect ships, platforms, icebergs, etc Detect et characterize oil pollutions Measure sea state conditions (wind, waves) and characterize meteorological and oceanographic phenomena Near-real time surveillance services with very strong timeliness requirements Satellites can be tasked up to 12 hours before image acquisitions Information retrieved from satellite radar images must be delivered in less than 30 minutes after image reception CLS April 2011

6 High resolution satellite radar imagery SAR imagery provides a non-cooperative picture of the maritime situation regardless of day/night conditions and cloud coverage. Routine large scale surveillance Oil pollution monitoring Icebergs detection Surveillance of large vessels & wakes Detetction of IUU fishing activites Detection of illegal traffics Zoom on Area of Interest Details Piracy Change detection MDA 2009 ESA 2009 Spatial resolution > 50 m Swath coverage 250 to 500 km (Sentinel-1, Radarsat-1&2 ScanSAR) Spatial resolution 25 m Swath Coverage 50 to 150 km (Sentinel-1, Radarsat, Cosmo Skymed, terrasar-x) This is a key technology of our satellite monitoring solutions Résolution 3 m Couverture 20 km x 20 km (ENVISAT, RARADSAT-1/2 Image) Spatial resolution < 5 m Swath coverage < 20 km (Radarsat, Cosmo SkyMed, TerraSAR)

16 Illegal fisheries

17 Surveillance of illegal fishing activities The Southern Indian Ocean Reference PAGE 17 Context: Protection of Patagonian Toothfish in the French and Australian EEZs of the Southern Indian Ocean Very remote areas with harsh meteorological conditions Proposed solution: 2004: Installation on Kerguelen Island of a satellite ground receiving station (ENVISAT, Radarsat-1&2) dedicated to the direct reception of satellite High resolution radar imagery Detection of illegal fishing activities based on : 1. Non cooperative vessels detection using satellite radar imagery 2. Correlation with VMS positions reported by licensed fishing vessels

19 Surveillance of illegal fisheries Workflow description in the Southern Indian Ocean PAGE 19 L Apache Le Malin Pioneering service worldwide to fight against IUU fisheries Operational without interruption since 2004 Proven deterrent effect

20 Detection of illegal logging

21 What is illegal logging? Illegal logging is the harvesting, transporting, processing, buying or selling of timber in violation of national laws. PAGE 21 Illegal logging exists because of increasing demand for timber, paper and derivative products (including packaging). Removed wood is also woodfuel used for basic energy needs. Illegal logging causes a significant economic impact as well as a social impact

22 Identification of the area of interest Pag e 22 PAGE 22 Areas of interest The illegal transhipment of rosewood on vessels requires mooring areas. Using Satellite AIS data and satellite Radar imagery, three potential areas for transhipment have been identified Area potentially favourable for transhipment due to the presence of a well protected bay and the mouth of a river Mooring area of the vessels detected on SAR image (RO-RO ANDREA) These areas are characterised by a facilitated access to the coast (presence of a beach) and are often close to the mouth of a river that flows through the national park of Masola Mooring areas of the vessels SOLAND et SEABIRD

23 Detection of the suspect vessels Pag e 23 PAGE 23 KIARA MMSI ; Type : General Cargo Flag : Antigua & Barbuda Picture taken on Sunday 8 December in the Antongila Bay The vessel SEABIRD was spotted during an illegal transhipment of woodrose The satellite AIS is dated from 10/12 at 0437Z (9 hours before the acquisition of the satellite radar image) The detected radar echoes may be linked to this transhipment operation SEABIRD MMSI ; Type : Fishing Vessel 3 vessels catch our attention KIARA : heading at 164 at a speed of 14 Knots SEABIRD : moored near the coast FAVOR : en route along the coast SEABIRD is highly suspected to be involved in illegal traffic of woodrose FAVOR MMSI ; Type : General Cargo

24 The case of the Oriental Pride PAGE 24 The Oriental Pride was spotted on three mooring areas, one of them being close to the national parc of Mananara It is stressed that she suddenly left few hours before the Authorities from Madagascar decided to arrest her. News from 05/06/2014: The oriental pride was intercepted by the customs from Singapore with 3000 tons of woodrose onboard

25 Sea state monitoring Wind and waves Sea state monitoring Wind and waves

26 Sea states measurements using SAR imagery PAGE 26 SAR imagery can measure oceans winds fields SAR imagery can measure global and coastal swell fields

27 High resolution coastal wind and swell fields Support to the offshore wind energy industry PAGE 27 Sentinel-1: The new European generation of satellite imagery radar will allow a long-term systematic coverage of coastal waters Unique opportunity for the Marine Renewable Energy sector : to better assess offshore wind resource in the frame of offshore wind farms siting studies to establish a High resolution coastal wind atlas k = 2.21 A = 8.67 m/s k = 2.28 A = 8.62 m/s Wind rose derived from SAR imagery [7.80 E ; N] Wind rose obtained from mast measurements (NorseWind FP7 project) [ E ; N]

28 Summary Satellite radar imagery is well adapted to the surveillance of the maritime domain and the non-cooperative detection of illegal activities Satellite tracking systems (Satellite AIS or VMS) are the good complementing technologies to go one step further towards the identification of suspect vessels Satellite radar imagery also offers the unique opportunity to measure sea states at high spatial resolution paving the way to the development of new coastal metocean applications The emergence of more and more EO radar mission players is also a good sign for users: more satellites and imaging capacities to meet users needs, more competition to the benefit of the market development
