São Gião Radio Telescope

São Gião Radio Telescope 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 São Gião Radio Telescope rather than just read about it. In short: The São Gião Radio Telescope is situated in the parish of São Gião, Portugal. It was constructed in 2015, with first light in December 2015.

Key takeaways

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

Reference excerpt

The São Gião Radio Telescope is situated in the parish of São Gião, Portugal. It was constructed in 2015, with first light in December 2015. The gregorian telescope has a diameter of 9.3 m. As of 2019 it is the biggest radio telescope in mainland Portugal. Two 3 phase motors drive the azimuth and elevation (or altitude) servo systems with an accuracy of 0.01 degree. The main reflector has a solid reflector surface that makes it suitable for observations of high frequencies up to 22 GHz. It is used to observe the hydrogen line from our galaxy and maser signals from star-forming regions and late evolution AGB or OH/IR stars. The frequencies used for the hydrogen line is 1.42 GHz and maser signals are measured on 1.612, and 12 GHz The data results obtained with the telescope were presented on EUCARA 2016 Dwingeloo Netherlands and on the ASTROFESTA 2018 in Constancia Portugal. The telescope data and methods are also referenced by universities like the Western Kentucky University, and societies like Ofiuco and the Society of Amateur Radio Astronomers. A report from the Correio da Beira Serra newspaper about the São Gião radio telescope, can be consulted here.

Worked examples

Example 1 — a first encounter with São Gião Radio Telescope

Start with the simplest possible case. Write down what São Gião Radio Telescope 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 São Gião Radio Telescope 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 São Gião Radio Telescope 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 São Gião Radio Telescope

In research: São Gião Radio Telescope 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 São Gião Radio Telescope 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: São Gião Radio Telescope is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomy in Portugal, Radio telescopes, so understanding it makes those chapters shorter.
In everyday life: Look for São Gião Radio Telescope 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.
