INSAT-2A

INSAT-2A is a 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 INSAT-2A rather than just read about it. In short: INSAT 2A was the first Indian multipurpose satellite. It was built in India and it came into operation in August 1992.

Key takeaways

INSAT-2A belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect INSAT-2A to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of INSAT-2A from memory before moving on to harder problems.

Reference excerpt

INSAT 2A was the first Indian multipurpose satellite. It was built in India and it came into operation in August 1992. The mission of the satellite was meteorology, Satellite based search and rescue, and Multipurpose Communication such as telecommunication, broadcasting of television and for disaster warning. The satellite weighed 1906 kg containing the fuel propellant. The weight of the satellite was 916 when there was no fuel.

History It is situated in the geostationary satellite at a longitude of 74 degree East. Its payload comprises a Radiometer of very high resolution for observing meteorological changes. This radiometer has a resolution of 2 km in the visible band and resolution of 8 km in the infra-red band. The satellite completed its mission on 30 May 2002, and is not in service since 2002. The mission life of the satellite was of 7 years. It was launched from French Guiana using the Ariane 4 as the Launch vehicle. In comparison to INSAT 1, this satellite can communicate in a better way, both in terms of quality as well as quantity. INSAT 2A has an advanced power amplifiers for catering communication terminals and was the first second generation satellite to replace the INSAT 1. This satellite will also enable the Indian National Satellite system to cover telecommunication circuits at larger distances.

Worked examples

Example 1 — a first encounter with INSAT-2A

Start with the simplest possible case. Write down what INSAT-2A claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 INSAT-2A 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 INSAT-2A 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 INSAT-2A

In research: INSAT-2A appears in 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 INSAT-2A 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: INSAT-2A is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1992 in India, INSAT satellites, Spacecraft launched by Ariane 4 rockets, so understanding it makes those chapters shorter.
In everyday life: Look for INSAT-2A 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 INSAT-2A in simple terms?

INSAT 2A was the first Indian multipurpose satellite. It was built in India and it came into operation in August 1992.

Why does INSAT-2A matter?

Because it connects several 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.
