F\u00f6r hundra \u00e5r sedan, den 15 april 1912, kolliderade RMS Titanic med ett isberg och sj\u00f6nk under sin resa \u00f6ver Nordatlanten, vilket ledde till att \u00f6ver 1 500 passagerare och bes\u00e4ttningsmedlemmar omkom. Idag f\u00e4rdas tusentals fartyg l\u00e4ngs samma rutt utan att n\u00e5gon omkommer \u2013 och det \u00e4r tack vare satelliterna.<\/p>\n<\/div>\n

Frederick Fleet hade till uppgift att st\u00e5 vakt p\u00e5 Titanic natten den 14 april 1912. De israpporter som Frederick l\u00e4mnade var den enda information som kapten Edward John Smith hade f\u00f6r att lotsa fartyget genom dessa farliga farvatten.<\/p>\n

Ett av de viktigaste resultaten av Titanic-katastrofen var f\u00f6rb\u00e4ttringen av sj\u00f6s\u00e4kerheten, genom inr\u00e4ttandet av den internationella konventionen om s\u00e4kerhet f\u00f6r m\u00e4nniskoliv till sj\u00f6ss och den internationella ispatrullen (IIP).<\/p>\n

Isbevakningens uppgift \u00e4r att \u00f6vervaka isberg och fastst\u00e4lla ett farozon f\u00f6r isberg. Det kan n\u00e4r som helst finnas tusentals isberg i de arktiska vattnen. Isbevakningens utmaning \u00e4r att fastst\u00e4lla hur m\u00e5nga isberg som kommer att driva s\u00f6derut mot farlederna. Hittills har inget fartyg som f\u00f6ljt Isbevakningens publicerade \u2018isbergsgr\u00e4ns\u2019 kolliderat med ett isberg!<\/p>\n

\"\"<\/figure>\n

Inledningsvis anv\u00e4nde ispatrullen fartyg f\u00f6r att genomf\u00f6ra rutinm\u00e4ssiga ispatruller, men \u00f6vergick till flyg\u00f6vervakning efter andra v\u00e4rldskriget. Idag \u00e4r flyg\u00f6vervakning den huvudsakliga metoden, men IIP har som m\u00e5l att ers\u00e4tta de kostsamma isflygningarna med satellitobservationer.<\/p>\n

Idag anv\u00e4nder ispatrullen satellitbaserade radarobservationer som komplement till flygobservationerna. Radar p\u00e5 satelliter \u00e4r utm\u00e4rkta f\u00f6r \u00f6vervakning av isberg eftersom de kan ta bilder genom moln och i m\u00f6rker.<\/p>\n

Sentinel-1, som ska skjutas upp 2013, kommer att avsev\u00e4rt \u00f6ka tillg\u00e5ngen p\u00e5 radardata och hj\u00e4lpa ispatrullen att undvika katastrofer som den som drabbade Titanic f\u00f6r ett sekel sedan.<\/p>","protected":false},"excerpt":{"rendered":"
