8 February 2002 Risk reduction on the CrIS program through rapid prototyping
Author Affiliations +
The Crosstrack Infrared Sounder (CrIS) is one of the sensors now under development for the National Polar-orbiting Operational Environmental Satellite System (NPOESS) program. In order to reduce program risk and verify instrument performance on the CrIS Program, various independent research projects were integrated into a prototype instrument. This was a rapid prototype built in 6 months that was similar to flight in the significant risk areas. This prototype instrument is referred to as the EDU1 (Engineering Development Unit). The coordination between the various, previously disjointed research tasks was a critical part of the effort. A layout of the flight CrIS instrument was the departure point for this effort. This layout was used to establish interfaces between the various modules. A set of clear cardinal requirements was established. The layout and the cardinal requirements therefore provided a conceptual overview and a basis for deriving lower level requirements. These requirements remained basically unchanged throughout the effort. The purpose of this paper is to describe the CrIS EDU1 system design and build, and summarize the key performance capabilities of the EDU1.
