Controlling the 1ESO13 spectrometer for spacelab and its data retrieval
Abstract
A discussion is presented of the Command and Data Management System (CDMS) for Spacelab and how it will be used to control the grille spectrometer. Spacelab, designed and built by the ESA, will be carried to and from an earth orbit by the U.S. Space Shuttle and will provide an Environmental Control Subsystem, an Electrical Power Distribution Subsystem with the electrical power being derived from the Orbiter fuel cells, the CDMS, and Common Payload Support Equipment. The functions of the CDMS are examined, including both low and high rate data acquisition and control, and a simplified block diagram of the CDMS is provided. The CDMS will control a grille spectrometer which will take medium resolution (0.1/cm) spectra in the near infrared (2.5-13 microns) region in small wavelength intervals in order to determine minor constituent concentrations in the upper atmosphere. The use of the CDMS for controlling the grille spectrometer is discussed, along with how the experimental data is handled until it finally reaches the ground support equipment in the payload operations control center for display and storage.
