Paper Abstract

Due to the new requirements of multi-site、multi-time、multi-satellites and highfrequency post-launch calibration, the hyperspectral post-launch cross-calibration system is developed. The system integrating global calibration-site network、calibration task automatic planning software and hyperspectral cross-calibration software can efficiently execute post-launch cross-calibration and dynamic performance evaluation. The application of the hyperspectral post-launch cross-calibration system is introduced. Hyperspectral imager Hyperion is used as reference sensor and HJ-1A/HSI is used as sensor to be calibrated. The system is used to acquire the cross-calibration coefficients of all HSI bands. The average differences of all HSI bands is 6.34% when cross-calibration coefficients are compared with site-calibration coefficients. The application feasibility of the post-launch cross-calibration system is validated preliminarily.
