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»
