摘要	The on-orbit intercalibration between satellite instruments is the central method to ensure the reliability, consistency and the continuity of observation data. The calibration uncertainty of 2% has been achieved combined with high-accuracy reference on-orbit instruments. This paper introduces the concepts and significance of the intercalibration and emphasizes which is a main way to correct the relative deviation of radiation calibration between instruments. It gives the basis conditions to complete the intercalibration and discusses the existing difficulties. Then, the realized process of the intercalibration is summed up such as the data collocating, filtering, correcting, reference changing and accuracy analyzing, and the effect factors on the calibration accuracy are analyzed. Moreover, it describes the current intercalibration methods for satellite optical remote sensing and needed conditions and summarizes the uncertainty of different intercalibration methods under different conditions for post-launch radiometric calibration of satellite remote sensors. In the end, this paper introduces a few international organizations and some ongoing joint campaigns with focusing on instrument calibration and validation, which shows the recent advance of research on the SI intercalibration in orbit. , 2015, Chinese Academy of Sciences.
