A method for the determination of three Euler angles for the SAC-C satellite magnetic mapper probe instrument package

Abstract The pre-flight determination of the relative orientation between the CSC vector magnetometer and the Star IMager in the Magnetic Mapper Probe on-board the Argentinean SAC-C satellite is described. Key elements of the instrumentation are given and the inter-calibration is attained using a temporary reference magnetometer and the satellite instrument package. The relative orientation is obtained with accuracy in the arcsec range. As opposed to previous methods the orientation of the reference magnetometer need not be known a priori, but is determined to within a few degrees, which is enough for the accurate determination of the CSC/SIM Euler angles.
