Lapan-TUBsat

Lapan-TUBsat 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 Lapan-TUBsat rather than just read about it. In short: Lapan- TUBSat is Indonesia’s first remote sensing satellite, made by the experts from National Institute of Aeronautics and Space (Lembaga Penerbangan dan Antariksa Nasional, Lapan) and Technische Universität Berlin (TUB) Germany. The uses of the satellite are for Indonesian natural resources observation and weather forecast for the Indonesian area.

Key takeaways

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

Reference excerpt

Lapan- TUBSat is Indonesia’s first remote sensing satellite, made by the experts from National Institute of Aeronautics and Space (Lembaga Penerbangan dan Antariksa Nasional, Lapan) and Technische Universität Berlin (TUB) Germany. The uses of the satellite are for Indonesian natural resources observation and weather forecast for the Indonesian area. Lapan-TUB Sat was launched aboard PSLV-C7 on 1 January 2007 from the Indian space centre in Sriharikota and still functioning well after the fifth birthday.

History Lapan-TUBSat is a micro satellite, weight of 56 Kilograms, and orbit at 630 kilometers above Indonesia. This satellite passes the polar orbital (from one polar to another) and across the archipelago for two or three times each day. Image of Lapan- TUBsat, now can only be received by Lapan ground station in Rumpin, West Java, called remote sensing image for West Indonesia. Afterward, ground station in Pare Pare, South Celebes and Biak Island, Papua, will be built to receive image from remote sensing satellite for Middle and East Indonesia. Before this discovery, image input and satellite data for the observation need, are received from other countries’ natural resources satellites, such as Landsat and NOAA (United States), SPOT (France), Radarsat (Canada), JRS (Japan), and also Feng Yun (China). Lapan as the institute that is made to fulfill this need could not fix the satellites’ orbital tracks, its coverage area, and time limit of the satellites rotation above Indonesia. Now, the Lapan-TUBsat can relay topography images from several regions in Indonesia. At the test phase, the satellite was aimed to Strait of Madura, North Java, Bangka Maritime and Strait of Malaya. Those areas classified as catastrophes areas of accident and flood. This point is consistent with the Lapan-TUBsat mission, giving attention to potentially dangerous areas in Indonesia.

Worked examples

Example 1 — a first encounter with Lapan-TUBsat

Start with the simplest possible case. Write down what Lapan-TUBsat 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 Lapan-TUBsat 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 Lapan-TUBsat 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 Lapan-TUBsat

In research: Lapan-TUBsat 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 Lapan-TUBsat 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: Lapan-TUBsat is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2007 in Indonesia, Earth observation satellites, Earth observation satellites of Indonesia, so understanding it makes those chapters shorter.
In everyday life: Look for Lapan-TUBsat 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.
