Abstract

The moderate-resolution imaging spectroradiometer (MODIS) instrument is currently being designed at Santa Barbara Research Center to be flown on board the earth observation system (EOS) polar orbiting spacecraft. The MODIS measures the scene radiance in 36 spectral bands from the visible to the long wave infrared regions with high radiometric accuracy and an instantaneous field of view (FOV) of 250, 500, and 1000 meters at nadir. Two on board microprocessors are used to control the instrument subsystems, and supervise the data acquisition and packet formatting. This paper describes the MODIS multiprocessor architecture, the on board data processing, the command and control subsystem, and the flight software necessary to run the instrument with a high degree of reliability.
