USA-192

USA-192 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 USA-192 rather than just read about it. In short: USA-192, also known as GPS IIR-16(M), GPS IIRM-3 and GPS SVN-58, is an American navigation satellite which forms part of the Global Positioning System. It was the third of eight Block IIRM satellites to be launched, and the sixteenth of twenty one Block IIR satellites overall.

Key takeaways

  • USA-192 belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect USA-192 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of USA-192 from memory before moving on to harder problems.

Reference excerpt

USA-192, also known as GPS IIR-16(M), GPS IIRM-3 and GPS SVN-58, is an American navigation satellite which forms part of the Global Positioning System. It was the third of eight Block IIRM satellites to be launched, and the sixteenth of twenty one Block IIR satellites overall. It was built by Lockheed Martin, using the AS-4000 satellite bus. USA-192 was launched at 19:12:00 UTC on 17 November 2006, atop a Delta II carrier rocket, flight number D321, flying in the 7925-9.5 configuration. The launch took place from Space Launch Complex 17A at the Cape Canaveral Air Force Station, and placed USA-192 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37FM apogee motor. By 17 January 2007, USA-192 was in an orbit with a perigee of 20,087 kilometers (12,481 mi), an apogee of 20,277 kilometers (12,600 mi), a period of 717.96 minutes, and 55 degrees of inclination to the equator. It is used to broadcast the PRN 12 signal, and operates in slot 4 of plane B of the GPS constellation. The satellite has a mass of 2,032 kilograms (4,480 lb), and a design life of 10 years. As of 2019 it remains in service.

Worked examples

Example 1 — a first encounter with USA-192

Start with the simplest possible case. Write down what USA-192 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 USA-192 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 USA-192 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 USA-192

In research
USA-192 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 USA-192 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
USA-192 is common in secondary-school and first-year university syllabi. It links to neighbouring topics American spacecraft stubs, GPS satellites, Spacecraft launched in 2006, so understanding it makes those chapters shorter.
In everyday life
Look for USA-192 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.
