The document provides a history of telecommunications including its roots in telegraph systems in the 19th century and the development of computers and packet switching in the 1950s and 1960s which enabled point-to-point communication between mainframe computers and terminals. It discusses how modern communications satellites use geostationary and other orbits to transmit data and how the World Meteorological Organization established a global network to transmit meteorological data from various sources.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching.<br />Satellite Communications<br />1238250405765A communications satellite is an artificial satellite stationed in space for the purpose of telecommunications. Modern communications satellites use a variety of orbits including geostationary orbits, Molina orbits, other elliptical orbits and low Earth orbits.<br />A satellite in a geostationary orbit appears to be in a fixed position to an earth-based observer. A geostationary satellite revolves around the earth at a constant speed once per day over the equator.<br />Telecommunications and meteorology<br />Is a global network for the transmission of meteorological data from weather stations, satellites and numerical weather prediction centers?<br />The World Meteorological Organization (WMO) is a specialized agency of The United Nations (UN) of which 179 States and 6 Territories are Members. It was created:<br /> To facilitate worldwide cooperation in the establishment of networks of stations for making meteorological observations <br />Research and training.<br />8096251002030-114300256332-666752487930<br />
