Sada aastat tagasi, 15. aprillil 1912, p\u00f5rkas RMS Titanic P\u00f5hja-Atlandi ookeani \u00fcletamise ajal j\u00e4\u00e4m\u00e4ega kokku ja uppus, mille tagaj\u00e4rjel hukkus \u00fcle 1500 reisija ja meeskonnaliikme. T\u00e4nap\u00e4eval l\u00e4bivad tuhanded laevad sama marsruuti ilma inimohvriteta \u2013 ja selles aitavad kaasa satelliidid.<\/p>\n<\/div>\n

Frederick Fleetil oli \u00fclesanne olla 14. aprilli 1912. aasta \u00f6\u00f6l \u201eTitanicu\u201d vahimees. Fredericki edastatud teave j\u00e4\u00e4olude kohta oli ainus teave, mille p\u00f5hjal kapten Edward John Smith sai laeva nendes ohtlikes vetes juhtida.<\/p>\n

\u00dcks Titanicu katastroofi olulisemaid tagaj\u00e4rgi oli meres\u00f5iduohutuse parandamine, mille raames v\u00f5eti vastu rahvusvaheline konventsioon inimelude ohutuse kohta merel ning asutati Rahvusvaheline J\u00e4\u00e4patrull (IIP).<\/p>\n

J\u00e4\u00e4patrulli \u00fclesanne on j\u00e4lgida j\u00e4\u00e4m\u00e4gesid ja m\u00e4\u00e4rata kindlaks j\u00e4\u00e4m\u00e4e ohtlik ala. Arktika vetes v\u00f5ib igal hetkel olla tuhandeid j\u00e4\u00e4m\u00e4gesid. J\u00e4\u00e4patrulli \u00fclesanne on kindlaks teha, kui palju j\u00e4\u00e4m\u00e4gesid triivib l\u00f5una poole laevateede suunas. Seni pole \u00fckski laev, mis on j\u00e4rginud j\u00e4\u00e4patrulli avaldatud \u2018j\u00e4\u00e4m\u00e4e piiri\u2019, p\u00f5rganud kokku j\u00e4\u00e4m\u00e4ega!<\/p>\n

Alguses kasutas j\u00e4\u00e4patrull rutiinsete j\u00e4\u00e4patrullide l\u00e4biviimiseks merelaevu, kuid p\u00e4rast Teist maailmas\u00f5da mindi \u00fcle \u00f5huseirele. T\u00e4nap\u00e4eval on \u00f5huseire peamine kasutatav meetod, kuid IIP eesm\u00e4rk on asendada kulukad j\u00e4\u00e4patrullilennud satelliidivaatlustest.<\/p>\n

T\u00e4nap\u00e4eval kasutab j\u00e4\u00e4patrull satelliidip\u00f5hiseid radarivaatlusi \u00f5hust tehtavate vaatluste t\u00e4iendamiseks. Satelliitidel asuvad radarid sobivad j\u00e4\u00e4m\u00e4gi j\u00e4lgimiseks suurep\u00e4raselt, kuna suudavad pildistada l\u00e4bi pilvede ja pimeduse.<\/p>\n

2013. aastal orbiidile saadetav Sentinel-1 suurendab oluliselt radariandmete k\u00e4ttesaadavust ja aitab j\u00e4\u00e4l\u00f5hkujatel v\u00e4ltida selliseid katastroofe nagu sajand tagasi juhtunud Titanicu hukku.<\/p>","protected":false},"excerpt":{"rendered":"
