GaindéSat‑1A

GaindéSat‑1A 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 GaindéSat‑1A rather than just read about it. In short: GaindéSat‑1A is Senegal's first satellite. It is a nanosatellite launched on 16 August 2024.

Key takeaways

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

Reference excerpt

GaindéSat‑1A is Senegal's first satellite. It is a nanosatellite launched on 16 August 2024. It is the first on‑orbit milestone of Senegal's broader SenSAT/SENSAT national program aimed at using space data for practical development needs and it was led by Maram Kairé. This made Senegal the 12th nation in Africa to launch a satellite into space.

Background The GaindéSat‑1A is the first satellite that was launched by the Senegal Space Study Agency, collecting data for state agencies like the Directorate of Water Resources Management and Planning as well as the National Agency for Civil Aviation and Meteorology. The satellite itself was designed and constructed in cooperation between Senegalese engineers and the Space Center of the French University of Montpellier (CSUM) for three years and it was launched on 16 August 2024 at 18:56 GMT from Vandenberg Space Force Base in California on SpaceX Falcon 9 rideshare mission. The rideshare mission also included 155 other small satellites. Its successor, the GAINDESAT‐1B, is also planned to be launched.

Worked examples

Example 1 — a first encounter with GaindéSat‑1A

Start with the simplest possible case. Write down what GaindéSat‑1A 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 GaindéSat‑1A 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 GaindéSat‑1A 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 GaindéSat‑1A

In research: GaindéSat‑1A 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 GaindéSat‑1A 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: GaindéSat‑1A is common in secondary-school and first-year university syllabi. It links to neighbouring topics Nanosatellites, Science and technology in Senegal, Spacecraft stubs, so understanding it makes those chapters shorter.
In everyday life: Look for GaindéSat‑1A 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.
