8 June 1994SEDS, earth, atmosphere, and space imaging system (SEASIS)
The Students for the Exploration and Development of Space (SEDS) Satellite #1 (SEDSAT 1) will fly a unique multi-role imaging system. The system, known as SEDS Earth, Atmosphere, and Space Imaging System (SEASIS) will be used to determine SEDSAT attitude during the spacecraft's deployment, study the optical properties of the atmosphere in the visible spectrum, monitor earth cloud cover, and serve as an educational tool for primary and secondary schools. The system has two visible CCD cameras (one camera has a 10 degree telephoto lens and the other camera has a 45 degree panoramic annular lens), two filter wheel systems, a frame grabber/digitizer, a multichip module processor, and 1 Gigabit of static memory. SEASIS is in the final prototype stages, and is approved for launch aboard SEDSAT 1 from the shuttle sometime in FY '96 or '97.
