Meteor-M No.2-4

Meteor-M No.2-4 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 Meteor-M No.2-4 rather than just read about it. In short: Meteor-M №2-4 (alternatively, Meteor-M number 2-4) is a Russian meteorological satellite which is part of the Meteor-M No.2 series of satellites that are designed to replace the old Meteor-3M series of satellites. The missions' primary tasks include environmental monitoring, surveillance of solar activity near the Earth, studying the interactions of the ocean and atmosphere, and exploring Earth's geology.

Key takeaways

Meteor-M No.2-4 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 Meteor-M No.2-4 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Meteor-M No.2-4 from memory before moving on to harder problems.

Reference excerpt

Meteor-M №2-4 (alternatively, Meteor-M number 2-4) is a Russian meteorological satellite which is part of the Meteor-M No.2 series of satellites that are designed to replace the old Meteor-3M series of satellites. The missions' primary tasks include environmental monitoring, surveillance of solar activity near the Earth, studying the interactions of the ocean and atmosphere, and exploring Earth's geology. The satellite also features a COSPAS-SARSAT search and rescue system. It was successfully launched on 29 February 2024 on a Soyuz-2.1b launch vehicle from the Vostochny Cosmodrome.

Instruments

Relevance for amateur radio hobbyists

The satellite continuously transmits sensor data and images of the Earth. Some of these transmissions are unencrypted and can be received using inexpensive equipment. Amateur radio operators and other radio hobbyists regularly receive pictures of the Earth transmitted using Low-rate picture transmission at 137.9 MHz or High-resolution picture transmission at 1705 MHz. Received data packets can be decoded using Free software, such as SatDump,

Worked examples

Example 1 — a first encounter with Meteor-M No.2-4

Start with the simplest possible case. Write down what Meteor-M No.2-4 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 Meteor-M No.2-4 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 Meteor-M No.2-4 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 Meteor-M No.2-4

In research: Meteor-M No.2-4 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 Meteor-M No.2-4 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: Meteor-M No.2-4 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2024 in spaceflight, Roscosmos, Spacecraft launched in 2024, so understanding it makes those chapters shorter.
In everyday life: Look for Meteor-M No.2-4 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.
