Development of space-qualified Fourier Transform Spectrometer (FTS) systems for long-life operational space missions requires development of new technologies. ITT Industries has been developing these new FTS technologies for the past 5 years, in anticipation of their use in FTS systems for operational meteorological satellites and other long-life space applications. Our objectives are to identify FTS technologies that have important mission advantages, design and build new components using these technologies, and prove the new technologies in a complete FTS interferometer technology testbed. This paper describes the process used at ITT to identify and develop these new technologies, the Dynamically Aligned Porch Swing (DAPS) interferometer technology testbed used to prove the new technologies, characterization tests of the DAPS used to verify the performance of the new technologies, and space qualification efforts now underway to verify that the new technologies can survive space environments. |
