UPM-Sat

UPM-Sat 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 UPM-Sat rather than just read about it. In short: UPM-Sat is a series of Spanish microsatellites developed by the Technical University of Madrid (UPM), in collaboration with the Instituto Nacional de Técnica Aeroespacial (INTA), for educational, scientific and technological purposes. UPM-Sat 1 The UPM-Sat 1, also called UPM/LB-Sat, was launched on July 7, 1995, from French Guiana on the flight V75 of the Ariane IV-40 launcher.

Key takeaways

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

Reference excerpt

UPM-Sat is a series of Spanish microsatellites developed by the Technical University of Madrid (UPM), in collaboration with the Instituto Nacional de Técnica Aeroespacial (INTA), for educational, scientific and technological purposes.

UPM-Sat 1 The UPM-Sat 1, also called UPM/LB-Sat, was launched on July 7, 1995, from French Guiana on the flight V75 of the Ariane IV-40 launcher. It weighed 47 kg. It had an operational life in orbit of 213 days, with a Sun-synchronous polar orbit at an altitude of 670 kilometers, completing one revolution around the Earth every 98 minutes.

UPM-Sat 2 The UPM-Sat 2 project aimed to develop a satellite with a mass less than 50 kg and overall dimensions less than 0.5 m x 0.5 m x 0.6 m. The UPM-Sat 2 satellite, also called M.A.T.I.A.S., was originally scheduled to launch in 1999. It was finally launched on September 3, 2020, on the flight VV16 of the Vega rocket.

Worked examples

Example 1 — a first encounter with UPM-Sat

Start with the simplest possible case. Write down what UPM-Sat 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 UPM-Sat 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 UPM-Sat 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 UPM-Sat

In research: UPM-Sat 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 UPM-Sat 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: UPM-Sat is common in secondary-school and first-year university syllabi. It links to neighbouring topics Communications satellites, Instituto Nacional de Técnica Aeroespacial, Satellites of Spain, so understanding it makes those chapters shorter.
In everyday life: Look for UPM-Sat 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 UPM-Sat in simple terms?

Why does UPM-Sat 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 UPM-Sat?

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.
