Telstar 19V

Telstar 19V 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 Telstar 19V rather than just read about it. In short: Telstar 19V (Telstar 19 Vantage) is a communication satellite in the Telstar series of the Canadian satellite communications company Telesat. It was built by Space Systems Loral (MAXAR) and is based on the SSL-1300 bus.

Key takeaways

Telstar 19V belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Telstar 19V to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Telstar 19V from memory before moving on to harder problems.

Reference excerpt

Telstar 19V (Telstar 19 Vantage) is a communication satellite in the Telstar series of the Canadian satellite communications company Telesat. It was built by Space Systems Loral (MAXAR) and is based on the SSL-1300 bus. The satellite was designed to provide additional capacity over the North Atlantic region. As of 26 July 2018, Telstar 19V is the heaviest commercial communications satellite ever launched, weighing at 7,076 kg (15,600 lbs) and surpassing the previous record, set by TerreStar-1 (6,910 kg/15230lbs), launched by Ariane 5ECA on 1 July 2009.

Launch Telstar 19V was launched on a SpaceX Falcon 9 Block 5 rocket into geostationary transfer orbit (GTO) from Space Launch Complex 40 (SLC40) at Cape Canaveral Air Force Station, Space Coast, Florida, United States, on 22 July 2018 at 1:50 AM EDT (5:50 UTC). The rocket core landed on the autonomous spaceport drone ship about eight and a half minutes after liftoff.

Worked examples

Example 1 — a first encounter with Telstar 19V

Start with the simplest possible case. Write down what Telstar 19V 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 Telstar 19V 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 Telstar 19V 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 Telstar 19V

In research: Telstar 19V 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 Telstar 19V 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: Telstar 19V is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2018 in Canada, Canadian broadcasting stubs, Communications satellite stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Telstar 19V 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.
