Heaviest satellite launched by EUMETSAT (European Organization For The Exploitation Of Meteorological Satellites) into space at 2,300 kg
Sentinel 3A is a government satellite operated by EUMETSAT (European Organization for the Exploitation of Meteorological Satellites) (ESA) for the purpose of earth observation (Earth Science).
Constructed by Thales Alenia Space (France), it was launched into space using Rokot as the launch vehicle from Plesetsk Cosmodrome on 16 February 2016. Sentinel 3A orbits around the Earth as a sun-synchronous LEO satellite.
Sentinel 3A has a launch mass of 2,300 kg (dry mass at 2,146 kg) and is expected to have a operational lifetime of 7 years. It navigates with the COSPAR ID 2016-011A and NORAD ID 41335.
Taking 101 minutes to orbit the Earth, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 802km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 804km. The eccentricity of the orbit is 1.39E-04 and it orbits at an inclination of 99 degrees to the equatorial plane of the Earth.
