Med utgangspunkt i over 30 \u00e5rs erfaring med \u00e5 sende jordobservasjonssatellitter i bane utvikler ESA n\u00e5 fem nye typer romfart\u00f8yer, kjent som Sentinel-satellitter. Hver Sentinel-oppdrag best\u00e5r av to identiske satellitter for \u00e5 sikre maksimal dekning av jorden.<\/p>\n<\/div>\n

Disse \u00ab\u00f8ynene i himmelen\u00bb vil sende tilbake enorme mengder data om jordens overflate og atmosf\u00e6re. Denne informasjonen vil bli brukt til \u00e5 dekke de operative behovene i Copernicus-programmet.<\/p>\n

Sentinel-1 er et radarbasert bildesystem som kan operere i all slags v\u00e6r, b\u00e5de dag og natt. Blant de mange oppgavene er overv\u00e5king av havisen i Arktis, kartlegging av havforurensning (for eksempel oljeutslipp), kartlegging av landbevegelser, unders\u00f8kelse av skog, vann og jord, samt st\u00f8tte til katastrofehjelp. Den polg\u00e5ende Sentinel-1A-satellitten ble skutt opp 3. april 2014. Dens tvilling, Sentinel-1B, ble skutt opp to \u00e5r senere, 25. april 2016.<\/p>\n

Sentinel-2 er et annet par satellitter i pol\u00e6r bane. De vil levere detaljerte optiske bilder av vegetasjon, jord- og vanndekke, samt kystomr\u00e5der. Sentinel-2A ble skutt opp 23. juni 2015. Sentinel-2B ble skutt opp 7. mars 2017.<\/p>\n

\"Sentinel-3\"

De ulike instrumentene om bord p\u00e5 Sentinel-3 skal m\u00e5le havoverflatens h\u00f8yde, temperaturen p\u00e5 land og p\u00e5 havoverflaten samt havets farge (som skyldes bittesm\u00e5 levende organismer). Sentinel-3A ble skutt opp 16. februar 2016, mens oppskytingen av Sentinel-3B er planlagt til 2017.<\/p>\n

B\u00e5de Sentinel-4 og Sentinel-5 skal overv\u00e5ke luftkvaliteten, ozonlaget, solstr\u00e5lingen og klimaendringene. Sentinel-4 vil best\u00e5 av flere instrumenter om bord p\u00e5 to Meteosat Third Generation-v\u00e6rsatellitter i bane over ekvator.<\/p>\n

Sentinel-5-instrumentene skal monteres p\u00e5 en MetOp Second Generation (MSG)-satellitt i pol\u00e6r bane, som flyr i en mye lavere h\u00f8yde enn Sentinel-4.<\/p>","protected":false},"excerpt":{"rendered":"
