Fünf weitere „Sentinel-Familien“ geplant
The Sentinels are currently being developed for the specific needs of the Copernicus programme. The Sentinels will provide a unique set of observations for Copernicus. They will consist of five different families:
Sentinel-1 will provide all-weather, day and night radar imagery for land and ocean services. The first satellite (Sentinel-1A) was launched on 3 April 2014. The second one (Sentinel-1B) is planned for launch in 2015.
Sentinel-2 will provide high-resolution optical imagery for land services. It will provide imagery of vegetation, soil and water cover, inland waterways and coastal areas. It will also deliver information for emergency services. The first Sentinel-2 satellite is planned for launch in 2014.
Sentinel-3 will provide high-accuracy optical, radar and altimetry data by measuring variables such as sea-surface topography, sea- and land-surface temperature, ocean colour and land colour with high-end reliability. The first Sentinel-3 is planned for launch in 2014 with operations shared between ESA and EUMETSAT.
Sentinel-4 will provide data for atmospheric composition monitoring. Sentinel-4 will be a payload embarked on Meteosat Third Generation (MTG), which is scheduled to be launched around 2020 and which will be operated by EUMETSAT.
Sentinel-5 will also be dedicated to atmospheric composition monitoring. Sentinel-5 will be a payload embarked on a MetOp Second Generation satellite, also known as Post-EPS, to be launched in 2020 timeframe and which will also be operated by EUMETSAT.
A satellite mission called Sentinel-5 Precursor is also planned to launch in 2015 in order to reduce data gaps between Envisat and Sentinel-5.
