RAL Space Involvement
In collaboration with Lockheed Martin, the Imaging Systems Division built camera electronics boxes (CEBs) for two of SDO's three remote sensing instruments: the Atmospheric Imaging Assembly (AIA), led from the Lockheed Martin Solar Astrophysics Laboratory in Palo Alto, California, and the Helioseismic and Magnetic Imager (HMI), led from Stanford University. The overall programme was managed by Lockheed Martin with CCD sensors from e2v technologies Ltd., Chelmsford, UK, and the CCD camera electronics from the UK's Rutherford Appleton Laboratory (RAL).
