Abstract
The Multi-viewing, Multi-spectral, Multi-polarisation Imager (3MI) is one of the payloads that will be on board of the MetOp-SG “Satellite A”, developed to provide information on atmospheric aerosols. 3MI is a space-based, wide field-of-view polarimeter that is designed to acquire sequential images of the same ground target, which are then combined with multiple spectral views in both un-polarized and polarized channels. This article presents the On-Ground calibration results on the 3MI PFM payload. The calibration request the measurement of a set of Key Data Parameters (KDP). These are needed in an instrument model. In the frame of 3MI calibration additionally to the geometrical, spectral and radiometric KDP, polarization and Stray Light are also considered. Because of 3MI wide FOV and polarization performance, dedicated Ground System Equipment GSE have been developed. Test results of the PFM calibration campaign are discussed and lessons learnt for the next campaign are proposed.
