Paper Abstract

The Upper Atmosphere Research Satellite (UARS) is dedicated to the study of the earth's atmosphere, composition, and temperature. It carries several instruments. Among them, WINDII is a Michelson interferometer used to observe wind and temperature in the upper mesosphere and thermosphere. The onboard calibration of the interferometer requires a He-Ne laser of frequency stability of 10-9. To be used in the space environment, particular specifications have been met by a special design described here. Performances of the system are shown and analyzed.
