UBAKUSAT

UBAKUSAT 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 UBAKUSAT rather than just read about it. In short: UBAKUSAT was a Turkish nanosatellite that was developed by Istanbul Technical University. It was launched into space on board a Falcon-9 rocket in April 2018 and was deployed into its orbit from the International Space Station in May 2018.

Key takeaways

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

Reference excerpt

UBAKUSAT was a Turkish nanosatellite that was developed by Istanbul Technical University. It was launched into space on board a Falcon-9 rocket in April 2018 and was deployed into its orbit from the International Space Station in May 2018. It was built as a technology demonstration and Earth observation satellite to provide voice communications for amateur radio stations around the world. It carried an experimental card, TAMSAT Simplesat, which allowed scientists to test its accuracy of measuring radiation from space. It was the fifth satellite to be built by students of Istanbul Technical University.

Development The contractual agreement covering the development and launching UBAKUSAT was signed between the Japanese government and the Istanbul Technical University on 8 September 2016, in Ankara. UBAKUSAT is a nanosatellite built by students of Istanbul Technical University's Faculty of Aeronautics and Astronautics, Space Systems Design and Test Lab (SSDTL). Technical support was provided by Turkey's Ministries of Transportation, Communication and Maritime in collaboration with the Japan Aerospace and Exploration Agency (JAXA) and Kyushu Institute of Technology. The satellite has an amateur radio and a linear transponder. UBAKUSAT's linear transponder is similar to the TURKSAT-3USAT satellite which was launched on 26 April 2013. UBAKUSAT is the fifth satellite to have been built by students of SSDTL. The first was ITUpSAT1 which was launched into low Earth orbit about 720 kilometres (450 mi) above Earth, on 23 September 2009 by a Polar Satellite Launch Vehicle rocket. On February 23, 2018, UBAKUSAT was delivered to JAXA officials at Tsukuba Space Center in Ibaraki. The satellite then underwent several tests at the space centre to simulate conditions that will be faced in space.

Launch On 2 April 2018, the satellite was carried on the International Space Station (ISS) on board a Falcon-9 rocket with help from the National Aeronautic and Space Administration (NASA). It was deployed from the space station into its orbit from the KIBO module on 11 May 2018. Its launch coincided with that of the 1KUNS-PF from Kenya and Irazú from Costa Rica. All three CubeSats carry amateur radio payloads with Irazú and 1KUNS-PF have telemetry beacons while UBAKUSAT carries a linear transponder for amateur radio. All three satellites were deployed into space from the Kibo module of the ISS by Japanese astronaut Norishige Kanai. UBAKUSAT was expected to orbit the Earth for a duration of between six and twelve months before de-orbiting.

Purpose UBAKUSAT was launched into space with the aim of providing voice communications for amateur radio stations around the world. The satellite had an experimental TAMSAT Simplesat card onboard which relayed data about space radiation to ground stations. The card was used in an experiment to assess its space radiation measuring technology.

Worked examples

Example 1 — a first encounter with UBAKUSAT

Start with the simplest possible case. Write down what UBAKUSAT 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 UBAKUSAT 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 UBAKUSAT 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 UBAKUSAT

In research: UBAKUSAT 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 UBAKUSAT 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: UBAKUSAT is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2018 in Turkey, CubeSats, Satellites deployed from the International Space Station, so understanding it makes those chapters shorter.
In everyday life: Look for UBAKUSAT 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 UBAKUSAT in simple terms?

Why does UBAKUSAT 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 UBAKUSAT?

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.
