UoSAT-12

UoSAT-12 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 UoSAT-12 rather than just read about it. In short: UoSAT-12 is a British satellite in Low Earth Orbit. It is the twelfth satellite in the University of Surrey series and was designed and built by Surrey Satellite Technology Ltd.

Key takeaways

UoSAT-12 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect UoSAT-12 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of UoSAT-12 from memory before moving on to harder problems.

Reference excerpt

UoSAT-12 is a British satellite in Low Earth Orbit. It is the twelfth satellite in the University of Surrey series and was designed and built by Surrey Satellite Technology Ltd. (SSTL). It was launched into orbit in April 1999 on board a Dnepr rocket from Yasny Russia.

Mission UoSAT-12 was an experimental mission used to demonstrate and test a number of new technologies. Imaging cameras and a high-speed 1 Mbit/s S-band downlink (the MERLION experiment) were tested. An Internet Protocol stack was uploaded to the satellite, allowing experiments in extending the Internet to space to be made by NASA Goddard as part of its Operating Missions as Nodes on the Internet (OMNI) effort. These now-proven technologies were later adopted by SSTL in the design of its Disaster Monitoring Constellation satellites.

Worked examples

Example 1 — a first encounter with UoSAT-12

Start with the simplest possible case. Write down what UoSAT-12 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 UoSAT-12 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 UoSAT-12 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 UoSAT-12

In research: UoSAT-12 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 UoSAT-12 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: UoSAT-12 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amateur radio satellites, Amateur radio stubs, European spacecraft stubs, so understanding it makes those chapters shorter.
In everyday life: Look for UoSAT-12 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.
