La vicenda dei Marò: possibile ausilio dei satelliti di telerilevamento?

Nel  sito internet di e- Geos società partecipata dell'ASI, dedicata alle osservazioni della terra,  vi sono indicazioni sulle molteplici applicazioni possibili.

Tra quste vi è anche la sorveglianza marittima: si visualizza ad esempio mediante la costellazione Cosmo-Skymed dei containers al largo di Singapore

La società partecipata dell'ASI pertanto avrebbe potuto monitorare anche la petroliera dalla quale i Marò avrebbero sparato ai  due pescatori indiani,uccjdendoli.

La questione dirimente importante per la giustizia indiana è accertare se la nave fosse in acque territoriali o non.

Ci si domanda se siano state utilizzate queste ed altre informazioni  ed in tal caso quale siano state le risultanze.

Chissà se  il Ministero degli Esteri ed il Ministero della Difesa si siano mai posto il problema!

Maritime Surveillance
Ship detection and tracking Satellite borne SAR instruments can provide an efficient way of detecting ships in the open sea and measuring, through wake and Doppler displacement, their speed and direction. Repeated observation can contribute to a maritime surveillance system, complementing information on routes from coastal radars and shipboard Automatic Identification Systems (AIS). e-GEOS grants unique access to a variety of SAR satellites: COSMO-SkyMed constellation, RADARSAT-1 & -2, ENVISAT and ERS-2. Particularly COSMO-SkyMed constellation significantly improves the role of SAR in this application because of its high revisit frequency. High spatial resolution observing modes can provide ship characterization / classification. For each ship, the system provides: geographical location date and time of detection estimate of size estimated speed & direction, where wake is visible MMSI code of the ship, obtained by integrating Earth Observation data with AIS and/or Satellite-AIS and/or Long Range Identification & Tracking (LRIT) systems data Near Real Time monitoring e-GEOS, thanks to its own ground station based in Matera (Basilicata region, Italy), is able to cover the Mediterranean basin with NRT services and provide oil spill and ship detection reports integrated with AIS, Satellite AIS, VMS (Vessel Monitoring System), LRIT and any other available in-situ data. Strategic Surveillance e-GEOS provides statistical traffic information derived from multi-temporal maritime picture analysis, and coastal areas monitoring, for critical route identification, patrol activity planning and decision support systems in case of crisis. Oil spill Oil damps down capillary waves on the sea surface. The SAR instrument can easily detect oil slicks as areas of lower back-scattered signal, provided that the sea is not too calm or too rough. Applications of oil slick detection encompass disasters (sinking tankers), illegal activities (tank washing) and oil exploration (natural seepage). The COSMO-SkyMed constellation can support large scale monitoring for oil spills with its ScanSAR observing mode. The short revisit time supports an operational use of a SAR-based oil spill monitoring service making it easier to link an oil spill with a specific ship. Available oil spill services and applications: routine and on-demand sea monitoring services statistical analysis support to environmental recovery measures following a spill integrated value-added products (automatic data integration chain) services provided on a continuous basis NRT performance (30 minutes from satellite pass) WebGIS delivery mode Sea Ice Sea ice information is required by a wide spectrum of users operating at high latitudes, including navigation (rivers, lakes and sea) and off-shore operations. Satellite Earth Observation and in particular SAR instruments represent a reliable tool for ice monitoring, providing a synoptic view which complements the accurate but low coverage reports from ships and airborne sources.
