First-year results of radiometric and MTF corrections for the KOMPSAT-I EOC sensor

The Republic of Korea KOMPSAT-I satellite has been in operation for over one year. The 6.6 meter resolution panchromatic Electro-Optical Camera (EOC) has shown a high degree of stability and fidelity in its digital signature, including its radiometric and Modulation Transfer Function (MTF) characteristics. The presentation will discuss the methods used in modeling these characteristics prior to launch, measurements after launch of the KOMPSAT-I, characterizations of the long-term stability and current image processing results.
