Global Telecommunication System

Global Telecommunication System is a computer 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 Global Telecommunication System rather than just read about it. In short: The Global Telecommunication System (GTS) is a secured communication network enabling real-time exchange of meteorological data from weather stations, satellites and numerical weather prediction centres, providing critical meteorological forecasting, warnings, and alerts.

Key takeaways

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

Reference excerpt

The Global Telecommunication System (GTS) is a secured communication network enabling real-time exchange of meteorological data from weather stations, satellites and numerical weather prediction centres, providing critical meteorological forecasting, warnings, and alerts. It was established by the World Meteorological Organization in 1951 under the World Weather Watch programme for the free and open exchange of meteorological information. The GTS consists of an integrated network of point-to-point circuits, and multi-point circuits which interconnect meteorological telecommunication centres. The circuits of the GTS are composed of a combination of terrestrial and satellite telecommunication links. They comprise point-to-point circuits, point-to-multi-point circuits for data distribution, multi-point-to-point circuits for data collection, as well as two-way multi-point circuits. Meteorological Telecommunication Centres are responsible for receiving data and relaying it selectively on GTS circuits. The GTS is organized on a three level basis:

The Main Telecommunication Network (MTN) The Regional Meteorological Telecommunication Networks (RMTNs) The National Meteorological Telecommunication Networks (NMTNs) Satellite-based data collection and/or data distribution systems are integrated in the GTS as an essential element of the global, regional and national levels of the GTS. Data collection systems operated via geostationary or near-polar orbiting meteorological/environmental satellites, including the Argos System, are widely used for the collection of observational data from data collection platforms. Marine data are also collected through the International Maritime Mobile Service and Inmarsat satellites. Use of GTS is to be phased out by 2033 with WIS2 as its replacement.

Worked examples

Example 1 — a first encounter with Global Telecommunication System

Start with the simplest possible case. Write down what Global Telecommunication System claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 Global Telecommunication System 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 Global Telecommunication System 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 Global Telecommunication System

In research: Global Telecommunication System appears in computer 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 Global Telecommunication System 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: Global Telecommunication System is common in secondary-school and first-year university syllabi. It links to neighbouring topics Data collection satellites, Meteorological data and networks, Organizations established in 1951, so understanding it makes those chapters shorter.
In everyday life: Look for Global Telecommunication System 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.
