Scientific paper

IFSI efforts in the development of the long-wavelength spectrometer (LWS) for the IR Space Observatory (ISO), scheduled for launch in 1993, are briefly reviewed. The LWS operates at 45-200 microns with resolution of about 200 (using a grating alone) or about 10,000 (using a grating with one of two Fabry-Perot etalons). Other LWS parameters include FOV 1.5 arcmin, sensitivity 1 x 10 to the -16th W/sq m, and SNR = 10 for a 10-sec high-resolution observation. Particular attention is given to the LWS data-processing unit (DPU), based on an 80C86 CPU and providing telecommand reception at 80 bps, data telemetry at 32,000 bps, detector sampling once every 0.5 msec, control of gratings and etalons, and continuous self-maintenance. Since the orbit of ISO exposes it to the earth radiation belts for about 2 h/day, the DPU is doubled, and the software is completely relocatable. An overview of the software design and a description of the low-noise dc-dc converter are included.
