摘要:KARI has been doing Calibration and Validation (Cal/Val) activities for the KOMPSAT-2 (KOrea Multi-Purpose SATellite-2) after launch at July 28th 2006. The Cal/Val for KOMPSAT-2 has already been done to guarantee the requirements of KOMPSAT-2 Users, and we are doing more Cal/Val activities to enhance the KOMPSAT-2 image quality for Users. The content of KOMPSAT-2 Cal/Val defined before launch has been a little changed after launch. After launch, we could find out the new and different phenomenon from analyzing the KOMPSAT-2 image data directly. Firstly, we tried to define the status of KOMPSAT-2 (e.g. the sequence of MS band, Line of Sight, Pointing accuracy, etc.). Secondly, every KOMPSAT-2 Cal/Val parameter was validated, and then KOMPSAT-2 was calibrated with the validated and uploaded initial value of them (e.g. Non-Uniformity Correction table, Misalignment between body and sensor etc.). Finally, we have done to implement the KOMPSAT-2 image data processing system with the results of K2 Cal/Val (e.g. De-noise, MTF compensation, Metadata, Users Manual, etc.)
