Pierre Kaufmann Radio Observatory

Pierre Kaufmann Radio Observatory 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 Pierre Kaufmann Radio Observatory rather than just read about it. In short: Pierre Kauffman Radio Observatory (Portuguese: Rádio Observatório Pierre Kauffman - ROPK), formerly known as the Itapetinga Radio Observatory (Portuguese: Rádio Observatório de Itapetinga - ROI), is a radio observatory located in the municipality of Atibaia in the state of São Paulo in Brazil. It is located approximately 7.5 km (4.7 mi) south of Atibaia and 40 km (25 mi) north of São Paulo.

Key takeaways

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

Reference excerpt

Pierre Kauffman Radio Observatory (Portuguese: Rádio Observatório Pierre Kauffman - ROPK), formerly known as the Itapetinga Radio Observatory (Portuguese: Rádio Observatório de Itapetinga - ROI), is a radio observatory located in the municipality of Atibaia in the state of São Paulo in Brazil. It is located approximately 7.5 km (4.7 mi) south of Atibaia and 40 km (25 mi) north of São Paulo. ROI was founded in 1970 by Universidade Presbiteriana Mackenzie (UPM). Control of the facility was passed to the National Institute for Space Research (INPE) in 1982. Today it is managed jointly by INPE, UPM, University do Vale do Paraíba (Univap), Universidade de São Paulo (USP), and Universidade Federal de Itajubá (UNIFEI). In addition to the telescopes, the observatory has living quarters for visiting scientists. ROI is located inside a small radio quiet zone. It was renamed in 2016 after Pierre Kauffman.

Telescopes A 13.7 m (45 ft) dish antenna was completed in 1974. It is housed in a radome which was replaced in 1990. It observes in bands from 18 GHz to 26 GHz and 40 GHz to 50 GHz simultaneously. It is used for both astronomical and solar observations. The Solar Patrol Equipment (Portuguese: Equipamento de Patrulhamento Solar - SPUA) is an array of 1.5 m (4.9 ft) dish antennas on a common mount. It monitors the intensity and linear polarization of radio waves from the Sun at 12 GHz. The Solar Radio Polarimeter (Portuguese: Rádio Polarímetro Solar - RaPoSo) is a 1.5 m (4.9 ft) antenna with two low-noise receivers centered at 7 GHz. It monitors the intensity and circular polarization of radio waves from the Sun. It was originally located at UPM's defunct Umuarama Radio Observatory near Campos do Jordão and is the oldest telescope at ROI.

Worked examples

Example 1 — a first encounter with Pierre Kaufmann Radio Observatory

Start with the simplest possible case. Write down what Pierre Kaufmann Radio Observatory 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 Pierre Kaufmann Radio Observatory 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 Pierre Kaufmann Radio Observatory 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 Pierre Kaufmann Radio Observatory

In research: Pierre Kaufmann Radio Observatory 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 Pierre Kaufmann Radio Observatory 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: Pierre Kaufmann Radio Observatory is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical observatories in Brazil, Buildings and structures in São Paulo (state), Radio telescopes, so understanding it makes those chapters shorter.
In everyday life: Look for Pierre Kaufmann Radio Observatory 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.
