Nigerian Communications Satellite

Nigerian Communications Satellite 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 Nigerian Communications Satellite rather than just read about it. In short: Nigerian Communications Satellite (NIGCOMSAT) Limited is a company under the supervision of the Federal Ministry of Communications and Digital Economy. Established to manage Nigeria's satellite communications program, it has overseen the launch and operation of the country's communications satellites.

Key takeaways

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

Reference excerpt

Nigerian Communications Satellite (NIGCOMSAT) Limited is a company under the supervision of the Federal Ministry of Communications and Digital Economy. Established to manage Nigeria's satellite communications program, it has overseen the launch and operation of the country's communications satellites. The company is responsible for NigComSat-1, Africa's first communications satellite, and its replacement NigComSat-1R, both developed in cooperation with Chinese partners.

Satellites

NigComSat-1 NigComSat-1, a Nigerian satellite ordered and built in China in 2004, was Nigeria's second satellite and Africa's first communication satellite. It was launched on 13 May 2007, on board a Chinese Long March 3B carrier rocket, from the Xichang Satellite Launch Centre in China. The spacecraft was operated by NIGCOMSAT LTD and the Nigerian Space Agency, NASRDA. On 11 November 2008, NigComSat-1 was de-orbit after running out of power due to an anomaly in its solar array. It was based on the Chinese DFH-4 satellite bus, and carried different transponders: 4 C band; 14 Ku band; 8 Ka band; and 2 L band. It was designed to provide coverage to many parts of Africa, and the Ka band transponders would also cover Italy. On 10 November 2008 (0900 GMT), the satellite was reportedly switched off for analysis and to avoid a possible collision with other satellites and was put into "emergency mode operation in order to effect mitigation and repairs". The satellite eventually was de-orbited later on in the same month. According to internal sources, the situation was caused by a problem with the solar panels of the satellite, which further lead to reduced functioning capacity. On 24 March 2009, the Nigerian Federal Ministry of Science and Technology, NIGCOMSAT Ltd. and CGWIC signed a further contract for the in-orbit delivery of NigComSat-1R satellite. NigComSat-1R was also a DFH-4 satellite.

NigComSat-1R Funded by insurance proceeds, a replacement for the failed satellite was launched from China in 2011.

2018 agreement In 2018, Nigeria signed an agreement with China to purchase two additional communications satellites with funds provided the Export-Import Bank of China. In exchange, China will receive part ownership of Nigerian Communications Satellite.

Worked examples

Example 1 — a first encounter with Nigerian Communications Satellite

Start with the simplest possible case. Write down what Nigerian Communications Satellite 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 Nigerian Communications Satellite 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 Nigerian Communications Satellite 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 Nigerian Communications Satellite

In research: Nigerian Communications Satellite 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 Nigerian Communications Satellite 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: Nigerian Communications Satellite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Government of Nigeria, Nigeria stubs, Telecommunications company stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Nigerian Communications Satellite 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.
