Abstract
The FTIR spectrometer is devoted to detect and study the concentration and spatial distribution of atmospheric trace gases and of natural ozone in the wavelength band 2-16 micrometers with spectral resolution 0.1 cm-1 and in the height range between 10km to 70km with vertical spatial resolution approximately 2km. Measurements will take place during sunset and sunrise for absorption spectrum. The instrument will be looking at the Sun through the Earth's atmosphere. These measurements will be very useful in the study of the Earth's environment. Moreover, the instrument is used to study the designing and manufacturing of light and compact FTIR spectrometers for low-cost small satellite missions. The instrument will be placed on board the small satellite CESAR, which is a Sun pointing satellite with position accuracy better than 1 degree. CESAR satellite orbital parameters are : perigee-400km, apogee-1000km, inclination 70 degrees, period-98.8 min. The general description of the instrument and preliminary measurements are presented.
