Nilesat 102

Nilesat 102 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 Nilesat 102 rather than just read about it. In short: Nilesat 102 is an Egyptian owned geosynchronous communications satellite that was launched by an Ariane 44LP rocket from Kourou, French Guiana on August 17, 2000, at 23:16 UTC by the European Space Agency. It was manufactured by the European company Matra Marconi Space (Astrium), and started official broadcasting on 12 September 2000 with an expected lifetime of 15 years.

Key takeaways

Nilesat 102 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nilesat 102 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nilesat 102 from memory before moving on to harder problems.

Reference excerpt

Nilesat 102 is an Egyptian owned geosynchronous communications satellite that was launched by an Ariane 44LP rocket from Kourou, French Guiana on August 17, 2000, at 23:16 UTC by the European Space Agency. It was manufactured by the European company Matra Marconi Space (Astrium), and started official broadcasting on 12 September 2000 with an expected lifetime of 15 years. The spacecraft weighed 1,827 kg at launch.

Manufacture It was manufactured by the European company Matra Marconi Space (Astrium). At launch, the spacecraft weighed 1,827 kg (fully fuelled). The receiver dish diameter is 50 cm to 75 cm. The transponder output power is 100 W and 12 Ku-band transponders with a bandwidth of 33 MHz. The maximum power consumption is 3.06 kW. The satellite utilizes a three axis stabilization system. The satellite is powered by two deployable solar arrays, with the power being stored on batteries.

Launch Nilesat 102 was launched by an Ariane 44LP rocket from Kourou, French Guiana on August 17, 2000, at 23:16 UTC by the European Space Agency.

Mission

Operations Nilesat 102 is operated by the Egyptian satellite Co. Nilesat, which was established in 1996 with the purpose of operating Egyptian satellites and their associated mission control center and ground stations. The two control centers are located in Cairo and Alexandria. The two satellites carried more than 150 TV channels, adding 50 more channels than when only Nilesat 101 was operational. Additional services provided include data transmission, turbo internet, and multicasting operations.

End of Mission Nilesat 102 was retired in June 2018 and moved to a graveyard orbit.

Worked examples

Example 1 — a first encounter with Nilesat 102

Start with the simplest possible case. Write down what Nilesat 102 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 Nilesat 102 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 Nilesat 102 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 Nilesat 102

In research: Nilesat 102 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 Nilesat 102 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: Nilesat 102 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000 in Egypt, Communications satellites in geostationary orbit, Satellites of Egypt, so understanding it makes those chapters shorter.
In everyday life: Look for Nilesat 102 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.
