Paper Abstract

Emissive reference spheres will be used to calibrate the orbiting SPIRIT III LWIR sensor with respect to point sources. Such spheres can be made to approximate very closely the spectrum of an ideal blackbody. However, the temperature of the sphere must be modelled to an accuracy of 1.6K or better during the calibration measurements in spite of various sources of uncertainty over the sphere's near-Earth orbit. Observations of both standard stars and emissive reference spheres will provide an unprecedented opportunity to compare the results of two entirely distinct calibration methods.
