The Russian Space Systems (RKS) holding has completed the modernization of the multispectral scanning unit (MSU-MR) for Meteor-M satellites. The improved instrument is installed on the Meteor-M No. 2-5 satellite, scheduled for launch in 2027–2028. The device will enhance the quality of Earth imaging for meteorology and environmental monitoring.
The updated MSU-MR allows for clearer images of the planet's surface due to improved characteristics and automated focusing. The instrument operates in six channels, capturing visible and thermal spectra, which helps track weather phenomena, natural and man-made processes. A new circular view mode simplifies equipment status monitoring. The modernization was based on the operational experience of Meteor-M satellites No. 2-2, No. 2-3, and No. 2-4.
The Meteor-M No. 2-5 satellite will be the sixth spacecraft in the Meteor-3M complex. It will collect data for weather forecasting, climate monitoring, disaster monitoring, and atmospheric research. Information from the instrument is sent to ground stations, where it is processed and transmitted to meteorologists, scientists, and other specialists.
Primary radiometric and geometric processing of images is carried out directly in the MSU-MR using its own computing resources and algorithms developed by our specialists on Earth. Onboard the spacecraft, the digital stream received from the MSU-MR is combined with the target information from the atmospheric temperature and humidity sounding module, the helio-geophysical instrumentation complex, and sent to ground receiving stations, where the information is processed and then transmitted to consumers — representatives of various sectors of the economy. The new MSU-MR is a significantly improved "traditional" hydrometeorological instrument that has proven itself successful for solving a wide range of tasks.
The satellites are developed by the Corporation "VNIIEM", and the system operator is the Scientific Center for Operational Monitoring of the Earth.
