    Abstract

    Using ultraviolet stars to finish the on-orbit calibration of far ultraviolet hyperspectral imaging spectrometer is an important step to achieve high precision remote sensing. However, in this way, the on-orbit calibration coefficients can not be directly used in target inversion. Therefore, the conversion of on-orbit calibration coefficients is of great significance to improve the on-orbit calibration accuracy of instrument. In this paper, the conversion process of the calibration coefficients is derived, a new equation of the calibration coefficients is given, the related verification experiments are carried out by using the developed instrument. The results show that the accuracy of target inversion can be improved by 40% by using the modified calibration coefficients.
