 THALES ALENIA SPACE EARTH OBSERVATION METEOROLOGY WEATHER SATELLITES

MTG-I1 set to revolutionize weather forecasting in Europe

Cannes, September 7, 2022 – Thales Alenia Space, a joint venture between Thales (67%) and Leonardo (33%), as prime contractor for the Meteosat Third Generation (MTG) satellites, is currently carrying out the final integration phase on the MTG-I1 satellite. The MTG-I1 will soon depart for the Guiana Space Centre in Kourou, French Guiana, where its launch is scheduled for the end of 2022 onboard an Ariane 5 rocket.

MTG-I1 is the first imaging satellite in the Meteosat Third Generation program, which aims to improve weather forecasting in Europe and Africa. Designed as a follow-on to the Meteosat Second Generation (MSG) series, the MTG program is a collaborative venture between the European Space Agency (ESA) and EUMETSAT  to ensure the continuity of high-resolution weather monitoring beyond 2040. Built by Thales Alenia Space in cooperation with OHB, the MTG satellites will operate in geostationary orbit 36,000 km above the Earth and will have a life span of 8.5 years.

The MTG program comprises six satellites: four imaging satellites (MTG-I) and two atmospheric sounding satellites (MTG-S) capable of providing 3D maps of the atmosphere — a major technological breakthrough.

The MTG-I1 satellite is equipped with a flexible combined imager (FCI), a technological gem that can provide a full image of the Earth every 10 minutes (versus 15 minutes for the previous generation) and includes a fast mode capable of providing images of Europe every 2.5 minutes. With a spatial resolution of 0.5 to 1 km, the satellite will improve the reliability of weather forecasts over a timescale of minutes to hours.

The MTG-I1 is also equipped with an extremely sophisticated lightning imager (LI), the first of its kind in Europe. Developed by Leonardo,  the LI, made of four cameras, will be able to detect cloud-to-cloud and cloud-to-ground flashes in all potential scenarios (for example during both night and day). This unique instrument will further our knowledge of how lightning is generated and improve emergency population warnings as well as weather nowcasting, traffic control safety and climate change awareness.

This first satellite in the MTG series will become operational in orbit during 2023 and will be joined by three other imaging satellites and two sounding satellites between 2024 and 2030. Together, they will form a geostationary constellation operated by EUMETSAT that will represent a big step forward in terms of the monitoring of extreme weather.

Цитата

"The Meteosat Third Generation constellation will revolutionize weather forecasting and deepen our understanding of the climatic changes taking place today. By integrating spectral and lightning imagery data, the MTG program will enable earlier prediction of severe storms and other significant weather events, which pose a growing threat to communities" commented Pierre Armand, MTG Program Director for Thales Alenia Space.

The MTG-I1 imaging satellite will leave the Thales Alenia Space site in Cannes in late September 2022. Special means will be deployed to transport the four-tonne satellite and its container to the Fos-sur-Mer port for shipment. The satellite is scheduled to be launched from the Guiana Space Centre in Kourou before the end of 2022, onboard an Ariane 5 rocket.

Mission Details
Galaxy 35 & 36
Intelsat's Galaxy 35 and Galaxy 36 satellites will operate in the upper portion of the C-band spectrum, a range of wireless radio frequencies that is used for critical telecommunications and data connectivity around the world. With this mission, Intelsat will meet the accelerated C-band spectrum clearing timelines established by the U.S. Federal Communications Commission (FCC).
Payloads: 2  Geostationary Transfer Orbit

MTG-I1
MTG (Meteosat Third Generation) is the follow-up system to Meteosat MSG series of geostationary satellites.
The satellite system will consist of a twin configuration of 3-axis-stabilised satellites: the Imaging mission satellite (MTG-I) and the Sounding mission satellite (MTG-S).
The payload proposed for MTG-I consists of the Flexible Combined Imager (FCI), Lightning Imager (LI), Data Collection System (DCS), and search and rescue (GEOSAR).
The FCI is expected to outperform MSG Spinning and Enhanced Visible and Infrared Imager (SEVIRI) observations on cloud, aerosol, moisture and fire by adding new channels in the solar domain and by improving temporal-, spatial-, and radiometric resolution. For instance, the FCI in its High Resolution Fast Imagery mode focusing on Europe/North Africa with a resolution down to 500 meters and a repeat cycle of 2.5 minutes will produce the greatest benefits to Nowcasting services.

Новый европейский метеорологический спутник прибыл на космодром во Французской Гвиане
После двухнедельного путешествия через Атлантический океан первый спутник третьего поколения Meteosat (MTG-I1) прибыл во Французскую Гвиану. Теперь инженеры займутся его подготовкой к запуску на ракете Ariane 5 в декабре, сообщает AstroNews.
Сейчас спутник находится в чистом помещении, инженеры миссии проводят дальнейшие проверки и готовят его к запуску.
MTG-I1 является первым из шести спутников, образующих полноценную систему MTG, которая будет предоставлять важнейшие данные для прогнозирования погоды в ближайшие 20 лет.
Миссия будет состоять из двух спутников MTG-I и одного MTG для зондирования (MTG-S), которые будут работать совместно.
Остальные MTG заменят спутники первого набора, чтобы обеспечить непрерывность передачи данных как минимум на два десятилетия.
Миссия MTG будет предоставлять данные с более высоким разрешением, скорость передачи увеличится, а также будут доступны новые данные для загрузки.
Спутники MTG-I оснащены двумя совершенно новыми инструментами для получения высококачественных данных, которые позволят улучшить прогнозы погоды: «Гибким комбинированным формирователем изображений» (Flexible Combined Imager, FCI) и «Устройством для отображения молний» (Lightning Imager).
«Гибкий комбинированный формирователь изображений» имеет больше спектральных каналов и способен получать изображения с более высоким разрешением по сравнению с текущим прибором Meteosat второго поколения SEVIRI.
«Устройство для отображения молний» будет непрерывно отслеживать более 80% земного шара на предмет молниевых разрядов, происходящих либо между облаками, либо между облаками и землей.
Этот новый инструмент позволит обнаруживать сильные штормы на ранних стадиях. Его детекторы настолько чувствительны, что смогут обнаружить относительно слабую молнию даже при полном дневном свете.
Спутники MTG-I также несут две меньшие полезные нагрузки, которые будут использоваться для сбора данных с удаленных научных маяков и для поиска аварийных маяков.

MTG-I1 ON THE HOME STRAIGHT FOR LAUNCH
21 November 2022
After six weeks of intense work, the first phase of the MTG-I1 launch campaign is coming to an end, paving the ground for the hazardous second phase of fuelling, before transferring the satellite to the Arianespace Launcher Authority, that is responsible for the final mating with the launcher in the third and last phase before launch.
A great acknowledgement goes to the dedication and professionalism of the industrial team of Thales Alenia Space and OHB.
The last two weeks were characterised by final system checks, advanced dry runs for the launch configuration and the training of launch countdown events involving both ESA and Eumetsat.
What is remarkable is that, despite the re-shuffling of activities due to the availability of manpower, the additional workload induced by Qualification Acceptance Review (QAR) closeout activities, and the re-test induced by NCR closeouts, the combined ESA-Eumesat industrial team could maintain the previously envisaged schedule of six weeks for this phase.
