e2v has signed a contract worth 2.8M euro with Astrium, Europe's leading space technology company. e2v will supply imaging sensors to equip the European Space Agency's (ESA) Sentinel 4 Ultraviolet Visible Near-infrared (UVN) instrument, which will gather data on the quality of the Earth's atmosphere and its chemical composition from geostationary orbit

Sentinel 4 is part of the Global Monitoring for Environment and Security (GMES) initiative, which is a joint undertaking of the European Commission and the European Space Agency. It will deliver environmental and security services in Europe, in response to the ever-increasing demands for effective environmental policies.

ESA is responsible for the Space component of GMES, of which the five families of Sentinel missions are key components. Within this programme, Sentinel 4 will be carried into orbit onboard the Meteosat Third Generation (MTG) geostationary satellite and enable seamless observations of Europe and North Africa to be taken hourly.

e2v's space qualified, custom Charge Coupled Device (CCDs) image sensors will be produced using cutting edge technologies, including back illumination, which delivers the best Quantum Efficiency (QE) and Modulation Transfer Function (MTF) over the wavelength range of interest for this hyperspectral imaging system.

The sensors are mounted in an e2v designed package assembly which manages the electrical, thermal, mechanical and optical interfaces to the instrument. The contract is carried out with funding from the European Union.

Hans Faulks, General Manager High Performances Imaging at e2v, said "e2v is delighted to sign this contract with Astrium. It demonstrates how e2v's imaging technology for Earth observation applications is well recognised and adds to more than 100 Earth observation programmes running with our high performance imaging sensors."

The Color of the Ocean: the SABIA-Mar Mission
Moffett Field CA (SPX) Jul 16, 2013
Remote sensing of ocean color is a currently well-established science that provides information about water composition and the depth of light penetration based on the ocean color, as seen from space. Ocean color satellites are part of an Earth observing system and, due to its importance in understanding the state of the ocean and its evolution, the international scientific community has agreed ... read more
