Abstract: Cross-calibration of satellite multispectral imaging systems is based on quantitative estimation of compliance of quasi-synchronous measures made by these sensors for the same underlying surface. The paper describes a method of channel-comparison measurements of different sensors using correction coefficients that allow difference between sensor parameters and measurement conditions. Presented are the results of radiometric cross-calibration of images obtained in closest channels of Belarusian satellite and Landsat 8, EO-1 (ALI & Hyperion) and AVIRIS imaging systems. The data of these sensors were chosen as a sample because of their regular adjustments, including subsatellite test sites measurements. As a result of cross-calibration it was established that the data of Belarusian satellite is reliable; this is because the differences of the satellite sensors (that are effective within the compared channels of radiance by the same underlying surface at quasi-synchronous measures) received from the research are within total uncertainties; these are determined by accuracy of absolute preflight energy calibration of the sensors, methodological error of comparison and difference of measurement conditions. The analysis of the images of the past few years did not reveal any tendencies of change in sensitivity of imaging systems of the Belarusian satellite.
