Abstract: The calibration on FY-2 in orbit is the key to the quantify analysis with the image of meteorological satellite.The calibration method of FY-2's visible,infrared and vapor channels in orbit is shown.The process of electric calibration and black body calibration of the channels in orbit is introduced.The result indicates that the infrared channel calibration curveis highly similar to the curve in the labortory.
