The Sentinel-3 mission will produce a consistent, long-term set of remotely-sensed marine and land data for (operational) ocean state analysis, forecasting and service provision. A comprehensive measurement system facilitating global ocean and land observation is required in order to provide data for advanced numerical forecasting models.
Sentinel-3 will determine parameters such as sea surface topography, sea/land surface temperature, ocean colour and land colour with high-end accuracy and reliability. For this purpose, it carries an advanced radar altimeter and a multi-channel optical imaging instrument.
To achieve near-global coverage and meet all scientific requirements, Sentinel-3 will be placed in a high-inclination, sun-synchronous polar orbit. Near-realtime data processing and delivery will allow operational services to continuously profit from the mission.
ESA carried out the Sentinel-3 definition phase in 2005/6, drawing on an industrial consortium led by Thales Alenia Space. The implementation phase started in autumn 2007 and the launch of the first Sentinel-3 satellite is planned for 2012.
