Intelsat V F-1

Intelsat V F-1 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 Intelsat V F-1 rather than just read about it. In short: Intelsat V F-1 (or Intelsat 501) was a geostationary communications satellite built by Ford Aerospace, it was owned by COMSAT. Launched in 1981, it was the second of fifteen Intelsat V satellites to be launched.

Key takeaways

Intelsat V F-1 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Intelsat V F-1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Intelsat V F-1 from memory before moving on to harder problems.

Reference excerpt

Intelsat V F-1 (or Intelsat 501) was a geostationary communications satellite built by Ford Aerospace, it was owned by COMSAT. Launched in 1981, it was the second of fifteen Intelsat V satellites to be launched. The satellite was based on the Intelsat V platform and its estimated useful life was seven years.

Satellite The satellite was box-shaped, measuring 1.66 by 2.1 by 1.77 metres; solar arrays spanned 15.9 metres tip to tip. The arrays, supplemented by nickel-hydrogen batteries during eclipse, provided 1800 watts of power. The payload housed 21 C-band and 4 Ku-band transponders. It could accommodate 15,000 two-way voice circuits and two TV channels simultaneously. It had a launch mass of 1928 kg. The satellite was deactivated in February 1997.

Launch The satellite was successfully launched into space on 23 May 1981, at 22:42:00 UTC, by means of an Atlas SLV-3D Centaur vehicle from the CCAFS, LC-36B.

Worked examples

Example 1 — a first encounter with Intelsat V F-1

Start with the simplest possible case. Write down what Intelsat V F-1 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 Intelsat V F-1 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 Intelsat V F-1 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 Intelsat V F-1

In research: Intelsat V F-1 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 Intelsat V F-1 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: Intelsat V F-1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1981 in spaceflight, Intelsat satellites, Spacecraft launched in 1981, so understanding it makes those chapters shorter.
In everyday life: Look for Intelsat V F-1 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.
