Overview of the complete CDS Ground System
Views of the CDS Engineering Model, located at RAL
The Engineering model was used in the testing of electrical subsystems at spacecraft level prior to building the flight instrument. Today it is used to develop and test studies prior to use on the flight instrument; to train people in the operations of CDS and to troubleshoot or test instrument upgrades.

The CDS Optical layout shows both the Normal Incidence and Grazing Incidence spectrometers, which are fed solar radiation from different angular segments of a Wolter II grazing incidence telescope. The scan mirror is used to scan different parts of the sun across the slit. Last revised on .
