MSTI-3 Calibration and Characterization

The objective of the Miniature Sensor Technology Integration - 3 (MSTI-3) calibration is to generate calibration equations for each of the payload sensors and fully characterize all spacecraft components. The calibration equations relate scene radiate flux to sensor output values. The parameters integrated into the calibration equations for the system include gain and integration normalization, linearity correction, dark offset, and non-uniformity correction. The absolute responsively, spectral out-of-band sensor response, and non-ideal performance of the mid-wave infrared (MWIR), short-wave infrared (SWIR), and visible imaging spectrometer (VIS) sensors will be measured. The calibration will include estimates of measurement uncertainties generated with descriptions of their applicability to any particular on-orbit measurement objective. The procedures cover each of the sensors, payload components, bus electronics, and integrated spacecraft testing at multiple sites including Science Applications International Corporation, the Space Dynamics Laboratory Utah State University, Phillips Laboratory, and on-orbit. All requirement, procedural and test result documentation related to the system calibrations are being collected in a single document.
