Tuginedes \u00fcle 30-aastasele kogemusele Maa vaatlus satelliitide lennutamisel, arendab ESA viit uut t\u00fc\u00fcpi kosmoses\u00f5idukit, mida tuntakse nimetusega Sentinel. Iga Sentinel-missioon koosneb kahest identsest satelliidist, et tagada Maa maksimaalne katvus.<\/p>\n<\/div>\n

Need taevas asuvad seirejaamad edastavad tohutuid andmehulki Maa pinna ja atmosf\u00e4\u00e4ri kohta. Seda teavet kasutatakse Copernicus-programmi operatiivvajadusteks.<\/p>\n

Sentinel-1 on igasuguste ilmastikutingimustega, \u00f6\u00f6p\u00e4evaringne radarpildistamise missioon. Selle paljude \u00fclesannete hulka kuuluvad Arktika merej\u00e4\u00e4 seire, mere reostuse (nt naftalekked) kontrollimine, maapinna liikumiste kaardistamine, metsade, vee ja pinnase uurimine ning katastroofiabi toetamine. Polaarorbiidil tiirlev satelliit Sentinel-1A lasti orbiidile 3. aprillil 2014. Selle kaksik, Sentinel-1B, lasti orbiidile kaks aastat hiljem, 25. aprillil 2016.<\/p>\n

Sentinel-2 on veel \u00fcks polaarorbiidil tiirlev satelliitide paar. Need satelliidid pakuvad \u00fcksikasjalikke optilisi pilte taimestikust, pinnasest ja veekattest, samuti rannikualadest. Sentinel-2A lasti orbiidile 23. juunil 2015. Sentinel-2B lasti orbiidile 7. m\u00e4rtsil 2017.<\/p>\n

Sentinel-3 mitmed m\u00f5\u00f5teriistad m\u00f5\u00f5davad merepinna k\u00f5rgust, maa- ja merepinna temperatuuri ning ookeani v\u00e4rvi (mille tekitavad pisikesed elusolendid). Sentinel-3A lasti edukalt orbiidile 16. veebruaril 2016, Sentinel-3B k\u00e4ivitamine on kavandatud 2017. aastaks.<\/p>\n

Nii Sentinel-4 kui ka Sentinel-5 j\u00e4lgivad \u00f5hukvaliteeti, osoonikihti, p\u00e4ikesekiirgust ja kliimamuutusi. Sentinel-4 koosneb mitmest seadmest, mis asuvad kahel Meteosat Third Generation ilmastiku satelliidil, mis tiirlevad ekvaatori kohal.<\/p>\n

Sentinel-5 m\u00f5\u00f5teriistad paigaldatakse polaarorbiidil liikuvale MetOp teise p\u00f5lvkonna (MSG) satelliidile, mis lendab palju madalamal k\u00f5rgusel kui Sentinel-4.<\/p>","protected":false},"excerpt":{"rendered":"
