The COSMO-SkyMed Constellation Monitors the Costa Concordia Wreck
نویسندگان
چکیده
On 13 January 2012, the Italian vessel, Costa Concordia, wrecked offshore Giglio Island, along the coast of Tuscany (Italy). The ship partially sunk, lying on the starboard side on a 22° steep rocky seabed, making the stability conditions of the ship critically in danger of sliding, shifting and settling. The tilted position of the ship created also pernicious conditions for the divers involved in the search and rescue operations. It became immediately clear that a continuous monitoring of the position and movements of the ship was of paramount importance to guarantee the security of the people working around and within the wreck. Starting from January 19, the Italian constellation of synthetic aperture radar (SAR) satellites, COSMO-SkyMed (CSK), was tasked to acquire high resolution images of the wreck. Thanks to CSK’s short response and revisiting time and its capability to acquire high resolution images in Spotlight mode, satellite data were integrated within the real time, ground-based monitoring system implemented to provide the civil protection authorities with a regular update on the ship stability. Exploitation of both the phase (satellite radar interferometry, InSAR) and amplitude (speckle tracking) information from CSK images, taken along the acquisition orbit, Enhanced Spotlight (ES)-29, revealed a general movement of the translation of the vessel, consistent with OPEN ACCESS Remote Sens. 2014, 6 3989 sliding toward the east of the hull on the seabed. A total displacement, with respect to the coastline, of 1666 mm and 345 mm of the bow and stern, respectively, was recorded, over the time period of 19 January–23 March 2012.

SAR interferometry analyses and experiments with COSMO-SkyMed
The new X-band SAR missions provide SAR images characterized by a much higher resolution, opening new possibilities for SAR interferometry. Thanks to the high resolution it is expected to find a larger number of coherent points or persistent scatterers per unit area, resulting in more detailed and accurate measurements by means of SAR differential interferometry techniques. Among the other char...

In the framework of the application of remote sensing to civil protection from floods, the problem of the detection of flooded areas and ground changes in high-resolution images is addressed in this paper. Specifically, the high-resolution multitemporal observation capability offered by the current COSMO-SkyMed synthetic aperture radar (SAR) constellation is exploited. This work is framed in th...
متن کاملA Mathematical Programming Algorithm for Planning and Scheduling an Earth Observing SAR Constellation
We consider the planning and scheduling problem of the COSMO-SkyMed constellation for the observation of the Earth. We define a simplified problem which only takes into account the most binding constraints of the real problem. We present a Lagrangean relaxation algorithm that provides upper bounds and we show that it can also be used to guide an existing heuristic algorithm to find better solut...
