MTS 945

MTS 945 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 MTS 945 rather than just read about it. In short: The MTS 945 GLONASS was the world's first smartphone that was compatible with GLONASS. The phone was available from Mobile TeleSystems, and was built by Qualcomm and ZTE.

Key takeaways

MTS 945 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect MTS 945 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of MTS 945 from memory before moving on to harder problems.

Reference excerpt

The MTS 945 GLONASS was the world's first smartphone that was compatible with GLONASS. The phone was available from Mobile TeleSystems, and was built by Qualcomm and ZTE. The phone was released on March 31, 2011. The phone was discontinued following low sales numbers.

History On December 28, 2010 the CEO of AFK Sistema Vladimir Yevtushenkov and the Russian Deputy Prime Minister Sergei Ivanov presented Vladimir Putin with the MTS 945 - the first phone equipped with a dual system GLONASS\GPS. During the meeting, Vladimir Yevtushenko claimed that the phone was equivalent to the iPhone 4, with the addition of GLONASS capabilities. The MTS 945 was developed jointly by Sitronics, Qualcomm, and ZTE, and went on sale in March 2011 at the price of 10 990 rubles (US$360). The initial plans for the phone called for 500,000 units shipped in the first batch, however in early 2011 it was reduced to 100,000. This was later reduced again to just 5000 units, which took six months to sell. In February 2012 ZTE announced that they were ending production of the phone due to poor sales. Before the MTS 945 was released ZTE was planning to create 3-5 phones with support for GLONASS, but the slow launch month put those plans into development hell, and they were eventually cancelled. Huawei, which was also planning to launch a phone with GLONASS around the same time decided to delay the launch of their own GLONASS compatible phones.

Specifications The phone is capable of receiving signals of two Global Navigation Satellite Systems: GLONASS and GPS. The phone's SoC is the Qualcomm MSM7230, and it runs Android.

Criticism Tests found that the MTS 945 performed comparably to or worse than comparable smartphones that also ran Android 2.2 and only received signals from GPS. At the same time, the MTS 945 GLONASS was significantly more expensive than the other devices this level.

Next model In May 2012, MTS launched a second smartphone with GLONASS, the MTS 962. The new model was launched at half the price of its predecessor, about 5300 rubles.

Worked examples

Example 1 — a first encounter with MTS 945

Start with the simplest possible case. Write down what MTS 945 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 MTS 945 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 MTS 945 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 MTS 945

In research: MTS 945 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 MTS 945 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: MTS 945 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Android (operating system) devices, GLONASS, Mobile phones, so understanding it makes those chapters shorter.
In everyday life: Look for MTS 945 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.

Why does MTS 945 matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study MTS 945?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
