e2v CCD Imaging Sensors Equip First Unmanned Spacecraft Sent To International Space Station

Chelmsford, UK - On March 9, 2008, e2v image sensors were launched into space on board the European Space Agency's (ESA) Jules Verne spacecraft, the first Automated Transfer Vehicle (ATV) to be sent to the International Space Station (ISS).

e2v CCD47-20 image sensors were selected by EADS SODERN as part of the two key systems they delivered for the ATV; an SED16 star tracker, an optical device used for determining the orientation of the spacecraft by measuring its position relative to stars, and a Videometer, a system EADS SODERN developed which is the primary rendezvous and docking sensor for the spacecraft.

The Jules Verne ATV was carried into orbit from the launch site in French Guiana and hauled almost 7 tons of cargo to the Station 400 km above the Earth. The spacecraft is the most powerful automatic spaceship ever built, having been equipped with its own propulsion and high-precision navigation system, which automatically guided it into dock at the ISS. The ISS relies on frequent deliveries of equipment, spare parts, food, air and water for its permanent crew. The unmanned ATV is essential in delivering supplies to it every 18 months or so and will then stay attached to the station, providing reboost and attitude control for up to six months.

Brian McAllister, Aerospace General Manager at e2v said "e2v has long relationships with SODERN, and ESA. We are pleased to deliver imaging sensors for the navigation and docking which directly enabled the successful delivery of supplies to the International Space Station."
