Damit k\u00f6nnen unabh\u00e4ngig von Tageslicht und Wolkenbedeckung Land- und Meeresoberfl\u00e4chen \u00fcberwacht werden, um zum Beispiel Behinderungen durch Meereis und \u00d6lverschmutzungen zu erkennen. Der Satellit hat eine Aufl\u00f6sung von 20 Metern und \u00fcberfliegt eine Region einmal am Tag.<\/p>\n<p>Die Daten werden bereits eine Stunde nach dem \u00dcberflug zur Verf\u00fcgung stehen, das ist eine deutliche Verbesserung zu bisherigen SAR-Systemen. In einigen Jahren wird Sentinel-1 einen <strong>Zwilling<\/strong> bekommen, der dann einen halben Tag versetzt Daten von einer Region liefern wird.<\/p>\n<p><strong>Sentinel-2<\/strong> ist ein polumlaufender Satellit, der multispektrale, hochaufl\u00f6sende Bilder zur Land\u00fcberwachung aufnehmen wird. Damit k\u00f6nnen zum Beispiel \u00dcberflutungsgebiete rasch identifiziert werden. Sentinel-2 wird 2014\/15 starten.<\/p>\n<p><strong>Sentinel-3<\/strong> ist ebenfalls ein polumlaufender Satellit, aber mit mehreren Instrumenten an Bord. Damit k\u00f6nnen mit hoher Pr\u00e4zision die Topographie der Meeresoberfl\u00e4che, See- und Landoberfl\u00e4chentemperaturen sowie Ozean- und Landf\u00e4rbungen \u00fcberwacht werden. Auch Sentinel-3 wird 2014\/15 starten.<\/p>\n<p><strong>Sentinel-4 und -5<\/strong> sind keine eigenen Satelliten, sondern Instrumente zur \u00dcberwachung der Atmosph\u00e4re, die zum einen an Bord des geplanten geostation\u00e4ren Satelliten &#8220;Meteosat Third Generation&#8221; (MTG), zum anderen an Bord des geplanten polumlaufenden Satelliten MetOp Second Generation eingebaut werden.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Der erste Satellit Sentinel-1 f\u00fcr das neue europ\u00e4ische Umwelt\u00fcberwachungsprogramm &#8220;Copernicus&#8221; durchl\u00e4uft derzeit die letzten Tests.
