MTG-I2

MTG-I2 is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand MTG-I2 rather than just read about it. In short: MTG-I2, also known as Meteosat-14, is a European geostationary satellite, part of the Meteosat Third Generation (MTG) system of weather satellites developed by EUMETSAT in cooperation with the European Space Agency (ESA). It is the second of four imaging satellites of MTG, completing its first trio together with MTG-I1 and MTG-S1/Sentinel-4A.

Key takeaways

MTG-I2 belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect MTG-I2 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of MTG-I2 from memory before moving on to harder problems.

Reference excerpt

MTG-I2, also known as Meteosat-14, is a European geostationary satellite, part of the Meteosat Third Generation (MTG) system of weather satellites developed by EUMETSAT in cooperation with the European Space Agency (ESA). It is the second of four imaging satellites of MTG, completing its first trio together with MTG-I1 and MTG-S1/Sentinel-4A. It will provide high resolution imagery over Europe every 2.5 minutes from a position at 9.5 degrees East—in line with Germany and Sardinia. It was launched in August 2026 on Ariane 62.

Instruments

Flexible Combined Imager The Flexible Combined Imager (FCI), a continuation of the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instruments on Meteosat Second Generation satellites, is designed to provide near-real-time monitoring of Earth's atmosphere by scanning the full Earth disc every 10 minutes and its upper quarter, containing Europe, every 2.5 minutes in 16 visible and infrared channels. It observes at wavelengths between 0.3 and 13.3 μm, and has a spatial resolution of 1 to 2 km.

Lightning Imager The Lightning Imager (LI) continuously detects the light pulses produced by different types of lightning: cloud-to-cloud, cloud-to-ground, and intra-cloud. It contains four cameras, capable of capturing 1,000 images per second, observing Europe, Africa, the Middle East, and partially also South America – in total covering 84% of the Earth disc. The instrument observes in a narrow spectral band centred on 777 nm and has a spatial resolution of around 10 km.

History

In September 2025, MTG-I2's two instruments, FCI and LI, were mounted on the satellite platform at Thales Alenia Space in Cannes. The completed spacecraft then underwent a thermal vacuum test. In March 2026, the satellite completed its last environmental tests, followed by a series of health checks. In April 2026, the satellite, together with FLEX and Sentinel-3C, was on show at a media event hosted by Thales Alenia Space in Cannes. MTG-I2 was then transported to Guiana Space Centre and on 6 July 2026, it was taken out of its protective casing at the spaceport. The satellite was launched by Ariane 62 on 27 August 2026 at 20:11 UTC from Guiana Space Centre. This was Ariane 6's first mission to geostationary orbit. After separation, the satellite was healthy and transmitting signals.

Worked examples

Example 1 — a first encounter with MTG-I2

Start with the simplest possible case. Write down what MTG-I2 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to MTG-I2 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about MTG-I2 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of MTG-I2

In research: MTG-I2 appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses MTG-I2 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: MTG-I2 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2026 in spaceflight, European Space Agency, Spacecraft launched in 2026, so understanding it makes those chapters shorter.
In everyday life: Look for MTG-I2 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is MTG-I2 in simple terms?

Why does MTG-I2 matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study MTG-I2?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
