NSS-6

NSS-6 is a astronomy 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 NSS-6 rather than just read about it. In short: NSS-6 is a communications satellite owned by SES. NSS-6 covers the whole of Asia with six high-performance Ku band beams, which can deliver broadband media to small businesses, ISPs or domestic rooftop antennas in those markets.

Key takeaways

NSS-6 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NSS-6 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NSS-6 from memory before moving on to harder problems.

Reference excerpt

NSS-6 is a communications satellite owned by SES. NSS-6 covers the whole of Asia with six high-performance Ku band beams, which can deliver broadband media to small businesses, ISPs or domestic rooftop antennas in those markets. The satellite delivers Direct-To-Home power and performance, as well as significant inter-regional connectivity. High-gain uplink performance (i.e. high receiver G/T figures) allows the use of small uplink antennas and/or amplifiers.

Manufacturer: Lockheed-Martin Original Orbital Location: 95° East Current Orbital Location: 86.85° West Launch date: December 17, 2002 Launch Vehicle: Ariane 4 Number of Transponders (physical): Ku band: 50 Number of Transponders (36 MHz Equivalent): 60 Saturated EIRP Range: Ku band: 44 to 55 dBW Frequency Band: Ku band uplink: 13.75 to 14.50 GHz Frequency Band: Ka band uplink: 29.5 to 30.0 GHz Frequency Band: Ku band downlink: 10.95 to 11.20 GHz, 11.45 to 11.70 GHz, 12.50 to 12.75 GHz

Worked examples

Example 1 — a first encounter with NSS-6

Start with the simplest possible case. Write down what NSS-6 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 NSS-6 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 NSS-6 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 NSS-6

In research: NSS-6 appears in astronomy 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 NSS-6 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: NSS-6 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Communications satellite stubs, Communications satellites in geostationary orbit, European spacecraft stubs, so understanding it makes those chapters shorter.
In everyday life: Look for NSS-6 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 NSS-6 in simple terms?

Why does NSS-6 matter?

Because it connects several astronomy 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 NSS-6?

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.
