Global Telecommunications System
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.[1][2] 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 circuits of the GTS are composed of a combination of terrestrial and satellite telecommunication links.Meteorological Telecommunication Centres are responsible for receiving data and relaying it selectively on GTS circuits.Marine data are also collected through the International Maritime Mobile Service and Inmarsat satellites.
