The multispectral satellite Earth remote sensing systems (KMSS) operate on board Meteor-M satellites, which are parts of the Meteor-3M space system of hydrometeorological and oceanographic support. KMSS are medium-resolution instruments designed to survey the Earth’s surface in a swath of about 1000 km in three VNIR spectral bands. KMSS-2 (launched in July 2019 on-board the Meteor-M No. 2-2 s/c) is the next modernized generation of ERS instrument after KMSS-M on the Meteor-M No. 2 s/c. In this work, the radiometric data of KMSS-M and KMSS-2 are analyzed. The comparison results of the KMSS and MODIS data obtained during in-flight calibrations in 2020 over the homogeneous snow cover of Antarctica are presented. The difference in the radiometric calibration of these instruments was estimated at 1–5 %, the root-mean-squared (RMS) deviation of the KMSS and MODIS reflectance measurements was found to be within 0.05.
