Europe Completes MTG Weather Constellation with MTG‑I2 Launch

The Imager is now en route to geostationary orbit to deliver 2.5‑minute regional imagery, lightning detection, plus Sentinel‑4 air‑quality measurements that will speed short‑term warnings.

Overview

  • MTG‑I2 launched from Kourou on an Ariane 6 and is currently in transfer toward its geostationary slot with orbital insertion and commissioning expected to take about ten days.
  • The new satellite completes the three‑ship Meteosat Third Generation system, joining the first Imager (MTG‑I1) and the Sounder (MTG‑S1) to operate as a coordinated constellation over Europe and North Africa.
  • MTG‑I2 carries a high‑resolution Flexible Combined Imager that will provide images every 2.5 minutes, a Lightning Imager that detects individual strikes day and night, and a spectrometer to supply Sentinel‑4 air‑pollution data.
  • National weather services expect faster warnings because the higher cadence gives a near‑continuous “film” of storms; the German Weather Service says this could allow detection of thunderstorm development about fifteen minutes earlier.
  • The 3.8‑tonne satellite was built for EUMETSAT by ESA with major hardware from OHB in Bremen, has a planned life of more than ten years, and paves the way for further MTG‑class launches starting in the early 2030s.
