Status Report on ANITA, an FTIR Spectrometer Flight Experiment for Manned Space Cabin Air Analysis

This paper reports on the development status of the flight experiment ANITA (Analysing Interferometer for Ambient Air). Based on ruggedized FTIR technology, ANITA represents a sophisticated air analyser for manned space cabins. In combination with specific analysis software developed through physical simulations and PLS (Partial Least Squares) statistical analyses, the monitoring system can detect and quantify over 30 gases nearly on–line. After testing, calibration and qualification of the system, an in-orbit-testing is scheduled around end of 2003.
