Radiometric On-Orbit Calibration of the Aerosol-UA Mission Scanning Polarimeter: Technique, Design Elements, and Illumination Angles
The concept of a device for the radiometric calibration of photometers or polarimeters on the Earth orbit using the Sun is considered. The shortcomings and advantages for the designing and materials of the key elements are analyzed. The illumination conditions are determined for the working element of the radiometric calibration assembly of the ScanPol scanning polarimeter aboard the YuzhSat satellite platform for different configurations in different orbit locations. The satellite orbit sections where solar illumination is optimal for the working element of this assembly from the viewpoint of the relation between the incidence and observation angles and minimization of the light caused by reflection from the Earth surface, atmosphere, ScanPol structure elements, and satellite platform are specified. The obtained results are planned for use in the development of an optimal design for the ScanPol radiometric calibration assembly to provide a necessary radiometric measurements precision during the Aerosol-UA space mission.
