This paper is a status report on the development of ANITA (Analyzing Interferometer for Ambient Air), an FTIR-based (Fourier Transform Infrared spectrometer) trace gas monitoring system. ANITA is scheduled for transport to the ISS (International Space Station) on the ATV (Automated Transfer Vehicle) maiden flight 'Jules Verne,' scheduled for launch April 2006. ANITA is calibrated to detect and quantify simultaneously 32 of the most important trace gases in the ISS atmosphere. ANITA operates fully automatic with one reading every 5 minutes. However, manual operation for non-local sampling is possible. To fulfill this measurement task a high-quality instrument has been developed and provided with sophisticated analysis software based on measurement simulations and advanced statistical regression techniques.
