The Meteor-MP hydrometeorological satellite planned for launch after 2025 will receive a new generation of Fourier spectrometers

The promising hydrometeorological satellites Meteor-MP will get a new generation Fourier spectrometers that have a longer range. They will be able provide twice the information as current devices. Vladimir Koshlakov, the Keldysh Center’s general director, announced this.

It looks like “Meteor M2”.
“For the promising polar-orbiting spacecraft Meteor-MP, we are developing a new generation Fourier spectrometer — IRFS-3, which has an extended spectral range (3.6-15.5) microns and significantly improved spatial characteristics”Koshlakov said.

He stated that the spectrometer would have three lenses and three photosenstors for each sub-spectral range. It will be possible to measure with only one step thanks to the photodetectors. Koshlakov stated that the information content of such devices should be several times greater than those from IKFS-2.

According to the Keldysh Center Director General, infrared sensors will be installed on new generations of satellites from the Elektro and Arktika series. Roshydromet set such a task for geostationary satellites Electro-M – the spectrometer must scan the Earth at minimum once an hour.

Koshlakov stated that although this is a complex piece of equipment, it could be mounted on the Arktika MP satellites to create an extremely elliptical orbit.

The Meteor M1 and Meteor M2 No.1 are now operational. Two devices are currently operating in orbit. The first Meteor M2 was lost in an emergency launch from Vostochny cosmodrome, 2017. The launches of devices 3 and 4 are planned for 2023, while the fifth and sixth should take place in 2024 and 2025, respectively. The next step should be the launch of the Meteor-MP vehicles of the new generation.

In early 2021, the first Arktika-M satellite was launched into orbit. The launch of the second Arktika-M satellite is planned for 2023. Three more satellites are scheduled to be launched in 2024-2025. Five satellites of Arktika-MP are expected to replace them after 2025.
