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).

Following the successful LPVE 2014, the European Space Agency (ESA) is inviting scientists and Cal/Val experts to present the latest results from their on-going research at the 2018 Workshop on Land Product Validation and Evolution (LPVE 2018).
The abstract submission deadline has been extended to 30 November 2017.

Working together for three decades, ESA and Eumetsat have been instrumental in positioning Europe as a leader in observing Earth from space. Continuing to share a vision, the two organisations have signed a statement that will strengthen Europe in meteorology and climate monitoring, and that will help to take the Copernicus programme into the future.
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.
