What is Sentinel-3?
Sentinel-3 is primarily an ocean mission, however, the mission is also able to provide atmospheric and land applications. The mission provides data continuity for the ERS, Envisat and SPOT satellites.
Sentinel-3 makes use of multiple sensing instruments to accomplish its objectives; SLSTR (Sea and Land Surface Temperature Radiometer), OLCI (Ocean and Land Colour Instrument), SRAL (SAR Altimeter), DORIS, and MWR (Microwave Radiometer).

The Copernicus Research and User Support (RUS) team would like announce an upcoming webinar on Ocean Colour Monitoring with Sentinel-3.
Please register now to the live webinar which is taking place on Wednesday 21 February 2018 from 14.30 to 16:00 CET.
Orbit Type: Sun-synchronous
Resolution and Swath Width:
In addition to the observation instruments, the Sentinel-3 spacecraft will carry the GNSS (Global Navigation Satellite System) and LRR (Laser Retro Reflector) instruments. GNSS will provide precise orbit determination and can track multiple satellites simultaneously. LRR will be used to accurately locate the satellite in orbit using a laser ranging system.
The dimensions of the craft are: 3.7 x 2.2 x 2.2 m with a weight (at time of launch) of 1250 kg.
Thales Alenia Space is the prime contractor, responsible for constructing the spacecraft and the SRAL instrument, as well as contributing to the supply of the SLSTR instrument.
