Bonn, Germany (SPX) Jul 28, 2009
This image - from the German TerraSAR-X radar satellite - shows the city of Kiel and the Kiel Fjord, an approximately 17-km long fjord or firth of the Baltic Sea on the northeastern shore of Schleswig-Holstein. The ships that were in this area at the time the image was captured are each marked with a circle.
The high resolution of TerraSAR-X images makes them ideally suitable for the rapid identification of ships. The image was taken on 18 June 2009. It was acquired in stripmap mode with a resolution of three metres.
Post haste - the real time service of DLR Neustrelitz
This is done by the automatic despatch of an email, including a 'quick look', in less than an hour. The processed pictures, which are subsequently offered to users for download, contain further information. In the case of ship identification, this is the position of the ships, which are automatically searched for by the computer processing the images. This application also offers the opportunity to discover hijacked ships, off the coast of Somalia for example.
Real time ship identification is required off the German coast as well. The German federal police ('Bundespolizei'), for example, use the TerraSAR-X radar images during 'Kieler Woche', to keep an eye on the many different ships attending.
The TerraSAR-X mission
TerraSAR-X works regardless of weather conditions, cloud cover or absence of daylight, and is able to provide radar data with a resolution of down to one metre.
DLR is responsible for using TerraSAR-X data for scientific purposes. It is also responsible for planning and implementing the mission as well as controlling the satellite. Astrium built the satellite and shares the costs of developing and using it. Infoterra GmbH, a subsidiary company founded specifically for this purpose by Astrium, is responsible for marketing the data commercially.
