A heliostat was designed and built as carrier for a 10 micrometer IR heterodyne spectrometer for transmission measurements in the Earth atmosphere for investigations of solar oscillations. The high wavelength resolution allows the determination of line profiles and transition frequencies with high precision. A series of highly resolved ozone absorption spectra lead to the vertical ozone distribution, in good agreement with reference measurements. An improvement of the results is expected after a more precise determination of ozone spectroscopic data from laboratory measurements. The measurement uncertainties are still too high to determine a frequency spectrum of solar oscillations.
