Infographic showing a close-up of the Sentinel-3 satellite body with solar panels visible against a dark background. Text provides a mission overview: Sentinel-3 is a European multi-instrument mission developed for the Copernicus Programme to systematically monitor the oceans, land, ice and atmosphere, operated by ESA and EUMETSAT. Main mission objectives and applications listed include ocean forecasting, sea-surface topography, ocean colour, sea and land surface temperature, marine ecosystems, inland waters, land monitoring, sea ice monitoring, wildfire and thermal anomaly detection, and climate monitoring.
Infographic showing two Sentinel-3 satellites during separation against a dark background, with an Earth observation image strip visible below. Text presents the Sentinel-3 launch timeline: Sentinel-3A launched 16 February 2016, Sentinel-3B launched 25 April 2018, Sentinel-3C scheduled for 2026, and Sentinel-3D planned.
Infographic showing the Sentinel-3 satellite and a rocket stage against a dark background with Earth visible below. Text lists orbital parameters: sun-synchronous, near-polar orbit at 814.5 km altitude, inclination of 98.65 degrees, 27-day repeat cycle, 385 orbits per cycle, and a revisit time of less than two days for OLCI and less than one day for SLSTR at the equator using the two-satellite constellation.
Infographic showing the Sentinel-3 satellite against a dark background with Earth visible at the bottom left. Text lists three onboard instruments: OLCI (Ocean and Land Colour Instrument), an imaging spectrometer with 21 spectral bands, 300 m resolution and 1270 km swath; SLSTR (Sea and Land Surface Temperature Radiometer), a dual-view scanning radiometer measuring sea and land surface temperature with a 740 km dual-view swath and 1400 km single-view swath; and SRAL (Synthetic Aperture Radar Altimeter), a radar altimeter measuring sea-surface height, waves and topography, operating in 100% SAR mode.
The #Sentinel3 constellation orbits Earth at 814.5 km, monitoring oceans, land, ice and atmosphere on behalf of the EU #Copernicus programme.
