Abstract
The moderate resolution imaging spectroradiometer (MODIS) presents a series of significant and interesting challenges in the area of system integration and test. Hughes has developed several clever and innovative solutions and so is successfully addressing these challenges as it nears completion of the protoflight model. The broad spectral coverage and large number of bands/detectors present unique challenges in areas such as background radiation, data handling, and the need for some highly capable test equipment. The several demanding performance parameters associated with the optical train often require solutions to be found among conflicting requirements. Specialized alignment techniques and tooling were developed to address image rotation caused by the folded optical train. The large field of view and need to test a wide range of system performance parameters on a tight schedule drove a comprehensive floor layout scheme with full rotation capability of the instrument and associated fixturing. The large number of optical surfaces combined with an extremely low scatter requirement led us to develop several initiatives to improve cleanliness.
