After many technical and programmatic challenges, the first satellite tv for pc of the subsequent technology of the Meteosat household has taken a major step towards its first flight, at the moment scheduled for launch in autumn 2022.

Following on from the success of the first and second technology of Meteosat satellites, the Meteosat Third Generation (MTG) will quickly take over the reins to make sure the continuity of knowledge for climate forecasting for the subsequent 20 years.The new technology of climate satellites will supply a major enhancement of the present imager capabilities offered by the Meteosat Second Generation, a real-time lightning imaging and an all-new infrared sounding functionality for early detection of extreme storms.Following the completion of the first flight mannequin of the Flexible Combined Imager (FCI) in July of this 12 months, the instrument has now been efficiently mounted onto the protoflight platform and the mixed meeting is now being ready for the Satellite Thermal Vacuum marketing campaign, which is scheduled to start out in early October in Cannes, France.This check will display the proper functioning of the satellite tv for pc within the simulated thermal situations seen in flight.

Final mating of the Flexible Combined Imager to the satellite tv for pc

Prior to this, the Flexible Combined Imager, developed by Thales Alenia Space, had undertaken an intensive system and environmental check marketing campaign, which concluded with the complicated ‘Optical Vacuum’ efficiency testing which measured all of the vital optical and radiometric traits of the instrument. The testing confirmed the anticipated state-of-the-art efficiency of the instrument.In parallel, the three-axis stabilised platform, developed by OHB in Bremen, had additionally undertaken in depth system testing demonstrating the platform’s efficiency and related knowledge dealing with hyperlinks with the devices.The platform had additionally participated within the System Validation Test (SVT) the place it was efficiently commanded from each Telespazio (demonstrating the nominal Launch and Early Orbit section sequence) and Eumetsat, the European Organisation for the Exploitation of Meteorological Satellites, (for routine operations).ESA’s Meteosat Programme Manager, Paul Blythe, commented, “It could be very pleasing to see the numerous progress that has been made during the last couple of years, regardless of the various technical and programmatic challenges encountered. Both the economic consortium and ESA groups ought to be very happy with what has been achieved notably when contemplating the unprecedented constraints introduced by the Covid disaster.

The Flexible Combined Imager beneath mechanical testing

“The performance results recently measured for the protoflight Flexible Combined Imager are truly impressive and reaffirm the world class capabilities that the European industry has to offer. I very much look forward to the launch of the MTG-I1 satellite at the end of next year, which will begin the deployment of the ‘Third Generation’ of geostationary meteorological observing capabilities.”The MTG-I1 satellite tv for pc would be the first of six satellites being developed within the body of the MTG contract, from which 4 ‘Imager’ satellites (MTG-I) and two ‘Sounder’ satellites (MTG-S) are being procured.The first MTG-S satellite tv for pc can be progressing nicely and is on observe for launch readiness towards the tip of 2023. Developed by OHB, the Infrared Sounder is beneath ultimate meeting in Munich, and is scheduled for instrument mechanical testing towards the tip of this 12 months.MTG is a cooperation between ESA and Eumetsat. ESA is answerable for the definition and implementation of the MTG satellites and procurement of recurrent {hardware}, whereas Eumetsat is answerable for working the spacecraft all through its lifetime. The MTG satellites will change the present Meteosat Second Generation (MSG) operational system for which the first of 4 satellites had been launched in 2002, and the final in 2015.
