Intelsat 14

Intelsat 14 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 Intelsat 14 rather than just read about it. In short: Intelsat 14 is a communications satellite owned by Intelsat located at 45° West longitude, serving the Americas, Europe, and African markets. Intelsat 14 replaced Intelsat 1R which was at the end of its design life.

Key takeaways

Intelsat 14 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Intelsat 14 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Intelsat 14 from memory before moving on to harder problems.

Reference excerpt

Intelsat 14 is a communications satellite owned by Intelsat located at 45° West longitude, serving the Americas, Europe, and African markets. Intelsat 14 replaced Intelsat 1R which was at the end of its design life. It was built by Space Systems Loral, as part of its LS-1300 line.

Communications payload Intelsat 14 has a C-band and Ku band payload, each of which is further divided to provide service to 2 each coverage areas. The C-band payload has an Americas beam which covers the southern part of the United States, all of Mexico, Central America, and all of South America. A second C-band beam provides coverage for Western Europe and Africa. The Ku band payload also has an Americas beam which covers the Alabama, Georgia and Florida, all of the Caribbean, Central America and all of South America except Brazil. The Ku band US/Europe/Africa beam covers the southern eastern United States, Western Europe, and the northern western African countries. Intelsat 14 also carries an experimental radiation-tolerant IP router payload that can be connected to several of the C and Ku band channels. This experimental payload is known as IRIS (Internet Routing in Space) demonstration.

Launch Intelsat 14 was launched from Cape Canaveral Air Force Station Space Launch Complex 41 November 23, 2009 on an Atlas V rocket flying in the 431 configuration. The satellite was released into a geosynchronous transfer orbit 1 hour and 58 minutes after lift-off.

Worked examples

Example 1 — a first encounter with Intelsat 14

Start with the simplest possible case. Write down what Intelsat 14 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 Intelsat 14 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 14 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 14

In research: Intelsat 14 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 Intelsat 14 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 14 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Communications satellites in geostationary orbit, Intelsat satellites, Satellite television, so understanding it makes those chapters shorter.
In everyday life: Look for Intelsat 14 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.
