Regular onboard calibration of satellite data is of great practical importance for the processing of remote sensing information. For flight cross-calibration it is proposed to use a geostationary satellite as a reference to calibrate polar orbiting satellites data on the example of the “Canopus–V–IR” and Himawary satellites. Authors use data from center for collective use “IKI–Monitoring”, united data catalogue of Planeta Research Centers for Space Hydrometeorology. The work has been done on theme «Monitoring»
