Heaviest satellite launched by EUMETSAT (European Organization For The Exploitation Of Meteorological Satellites) into space at 2,300 kg
Operated by EUMETSAT (European Organization for the Exploitation of Meteorological Satellites) of ESA, Sentinel 3A is a government satellite launched for the purpose of earth observation (Earth Science).
A sun-synchronous LEO satellite, it was launched into space using Rokot as the launch vehicle from Plesetsk Cosmodrome on 16 February 2016. Sentinel 3A was constructed by Thales Alenia Space (France).
Designated with COSPAR ID 2016-011A and NORAD ID 41335, Sentinel 3A is designed to operate in space for a lifetime of 7 years. It has a launch mass of 2,300 kg and dry mass of 2,146 kg.
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.
