Hydrometeorological satellite “Meteor-M” No. 2-4 is planned to be launched at the end of the year, said Ildar, General Director of the Scientific and Production Corporation “Space Monitoring Systems, Information, Control and Electromechanical Complexes” named after A. G. Iosifyan (VNIIEM, part of Roscosmos) Khalilyulin.

The Soyuz-2.1b will soon launch from the cosmodrome in the Amur Region with the Meteor-M hydrometeorological satellite No. 2-4 and a payload of other small spacecraft. It will launch from Cosmodrome Site 1S at the Vostochny Cosmodrome, Siberia, Russian Federation

The Fregat upper stage is a universal upper stage that is designed to launch spacecraft into various orbits. It is used as part of various types of launch vehicles, including Soyuz-type launch vehicles. The Fregat upper stage was designed and produced by the Scientific and Production Agency named after S.A. Lavochkin.

The Meteor-M 2-4 spacecraft is a weather satellite that is designed to provide global observations of the Earth’s atmosphere and oceans. The spacecraft is equipped with a variety of instruments that can be used to monitor weather patterns, climate change, and other environmental phenomena. In addition to the MSU-MR Sensor package, it will, like M2-3 have aboard it the KMSS (Multispectral Scanning Imaging System).

The instrument comprises three cameras in the VNIR range; two cameras (MSU-100) have a focal length of 100 mm; the third one (MSU-50), has a focal length of 50 mm. The two MSU-100 cameras are tilted ±14º in cross-track to each side of the nadir; together they cover a swath width of 960 km, which is close to the swath of MSU-50. 

Each camera has a focal plane with 3 CCD lines (each covered with a corresponding filter) behind a common lens. The three-line camera system (with 3 CCD-lines in a focal plane and 1 lens, the corresponding detector elements of different bands look necessarily in different along-track directions) provides the following along-track observation directions: ±17º and 0º (nadir) for MSU-50, and ±8.7º and 0º for MSU-100. The KMSS instrument represents simply the mounting fixture of three separate cameras, and the KMSS image will be an image of 3 separate cameras put together in ground processing.

MTVZA-GY (Microwave Imaging/Sounding Microwave Radiometer) will also be onboard The objective of the MTVZA-GY instrument is to monitor ocean and land surfaces as well as global atmospheric parameters such as temperature and water vapor profiles and to obtain sea surface wind profiles. MTVZA-GY is a conical scanning instrument with a common field of view for imaging and sounding channels (simultaneous multispectral and polarization measurements), due to the single antenna design.

Meteor M2-4 is a clone of Meteor M2-3 and as such it can be expected to function on 137.1 and 137.9 MHz for LRPT and 1.7GHz for HRPT. As of 2023 Meteor M2-5 and Meteor M2-6 were in production at VNIIEM Corporation. The launch of the sea-monitoring Meteor-M No. 3, which was custom-designed to observe oceans with a high-resolution phased-array radar, has been pushed beyond 2025 due to a lack of funding.

December 16: A Soyuz-2.1b rocket to launch the 2,100-kilogram Arktika-M No. 2 remote-sensing satellite into a highly elliptical orbit. This is a priority satellite for Russian Weather Observation as the Meteor Satellites do not do a very good job of weather monitoring over the important Arctic regions.
