Sagem delivers first detectors for Eclairs telescope, primary instrument on the SVOM space observation satellite
Paris, November 10, 2010
Sagem (Safran group) has delivered the first prototype sensors to space research center CESR (1) for the Eclairs telescope, the main payload to be carried by the scientific satellite SVOM (Space-based multi-band Variable Object Monitor).
The satellite’s X-ray and gamma ray detection modules, developed and produced by Sagem’s Safran Electronics division in Valence, each comprise 32 cadmium telluride (CdTe) detectors and an application-specific integrated circuit (ASIC), based on high-temperature co-fired ceramic (HTCC) elements. The Eclairs telescope will group 200 of these subassemblies to form a detector with total sensing area of 1,000 square centimeters.
The SVOM mission is primarily designed to study gamma-ray bursts, the most violent events in the Universe – not counting the Big Bang of course. The celestial bodies created by gamma-ray bursts (the huge explosion of a massive star at the end of its life) offers huge potential for cosmological studies, in particular the possible detection of the first stars in the Universe, and a survey of the cosmos.
The Eclairs telescope is the primary mission instrument, and is being built under the auspices of French space agency CNES, in conjunction with the CESR lab and the French atomic energy commission CEA. The SVOM spacecraft will be launched in 2015 as part of a joint French-Chinese mission organized by the Chinese space agency, the Chinese Academy of Sciences and CNES.
The selection of Sagem and its Safran Electronics division for the SVOM program further consolidates their role as a leading supplier of integrated electronics for platforms operating in the harshest environments, including aircraft, launch vehicles and satellites. Sagem’s acknowledged expertise in this field was a decisive factor in its selection by CNES and CESR.
Sagem already supplies hybrid products and printed circuit boards for civilian satellites (ERS 1 and 2, Metop, Envisat, Spot), and contributes to the military satellites Helios, Pleiades and CSO Musis.
