Telkom-3S

Telkom-3S 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 Telkom-3S rather than just read about it. In short: Telkom-3S is an Indonesian geostationary communications satellite built as a replacement of Telkom-3 that was lost due to a launch failure on 6 August 2012. Telkom-3S was successfully launched on 14 February 2017, at 21:39 UTC and commissioned into service on 17 April 2017.

Key takeaways

Telkom-3S belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Telkom-3S to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Telkom-3S from memory before moving on to harder problems.

Reference excerpt

Telkom-3S is an Indonesian geostationary communications satellite built as a replacement of Telkom-3 that was lost due to a launch failure on 6 August 2012. Telkom-3S was successfully launched on 14 February 2017, at 21:39 UTC and commissioned into service on 17 April 2017.

Satellite description Telkom-3S is fitted with 24 C-Band transponders, 8 extended C-Band transponders and 10 Ku-Band transponders. The C-band payload will cover Indonesia and Southeast Asia, while the extended C-band payload will cover both Indonesia and part of Malaysia. The Ku-band payload will specifically cover Indonesia. Telkom-3S will provide high-definition television (HDTV) services along with mobile communications and internet applications.

Worked examples

Example 1 — a first encounter with Telkom-3S

Start with the simplest possible case. Write down what Telkom-3S 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 Telkom-3S 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 Telkom-3S 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 Telkom-3S

In research: Telkom-3S 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 Telkom-3S 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: Telkom-3S is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2017 in Indonesia, Communications in Indonesia, Communications satellites, so understanding it makes those chapters shorter.
In everyday life: Look for Telkom-3S 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 Telkom-3S in simple terms?

Why does Telkom-3S 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.

How should I study Telkom-3S?

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.
