Medium-resolution multispectral satellite imaging system KMSS-2 started operations on board Meteor-M No. 2-2 spacecraft that was launched in July 2019. The system consists of two identical imagers MSU-100TM with three spectral channels at 0.55, 0.65, 0.85 mkm central wavelengths, 55 m ground sample distance at nadir and common swath of more than 1000 km. KMSS-2 has principal improvements to the previous instruments of KMSS series operating in orbit since 2009 onboard Meteor-M No. 1/2 meteorological satellites. Among the improvements are: optical alignment of the spectral channels, new linear charge coupled detectors with enhanced dynamic range and higher signal-to-noise ratio, 10 bit per channel signal quantization, individual integration time, dark current level and gain selection for each channel. The purpose of the improvements was to enhance data quality with the same instrument-to-spacecraft interfaces, data transmission channel and control logics proven by previous system operation. Imaging data are synchronized with spacecraft position and attitude measurements to allow image georeferencing during the ground processing procedures.
