1 | , Artificial communication satellites are placed in an orbit around the Earth. They relay radio and television signals around the curved surface of the Earth and thus serve the purpose of intercontinental radio and television transmission. There are two types of satellites in the orbit: active and passive. As for active satellites, they are used to receive, amplify, and retransmit signals being sent for the purpose of communication. The function of passive satellites is only to reflect the transmitted signals from the surface of the Earth..: |

1 | , Nowadays spaceships may be launched from the Earth and return to it or they may be launched from the Earth and not return to it. They may also be launched from a satellite space station. Manned and unmanned (automatic) spaceships of nowadays are used for space exploration and bring back information on space. The first spaceship was a high altitude rocket. It was launched from the Earth, travelled through the atmosphere into space and returned to the Earth. Information on space collected by the rocket was transmitted to the Earth via telemetry.

Practically, one can say that communication is carried out due to the energy being transmitted over the transmitting lines. Lines used for energy transmission may be classed into the following three types: overhead, indoor and underground. Naturally, these types are different in construction and in the elements they are made of. As for overhead lines, they include line conductors, insulators and supports.: |

For example, it became possible for people to receive television programs through cables. Modern cable is a complex wire system that makes it possible to transmit a number of television signals at the same time. People today also widely use videotape recorders to record television programs. One of the most interesting inventions of today is also the usage of satellites for video and audio communication. People can receive programs through using satellites.: |

1 | , Artificial communication satellites are placed in an orbit around the Earth. Artificial satellites are being used to receive and reflect back information about the upper atmosphere and the ionosphere. It is a well-known fact that the ionosphere forms part of the Earth's upper atmosphere. It reflects electromagnetic radiations of radio frequencies, which makes it possible to carry out intercontinental radio transmission round the curved surface of the Earth.: |

1 | , As we know, electric energy is transmitted to different parts of the country means of transmitting lines. The lines include thick wires made of different metals. A number of metal wires put together form one thick cable and a pair includes two insulated conductors forming a metallic circuit. Thus the basic technological part of energy transmission process is a long transmission line, and a cable is its main part.: |

1 | Communication between INFORMATION SOURCES can be carried out through the combination of the sources into networks. Telephone and telegraph networks may serve as examples. Telex has been used for communication for a long time. Not long ago cable transmission has also become used for the same purpose. As for computer networking, it is also highly developed in every sphere of communication and is very popular locally and internationally.: |
1 | The RADIO-CONTROLLED SPACESHIP named Vostok was equipped with two-way radio transmitters operating on short and ultra-short waves. These transmitters enabled the cosmonaut to send signals to the Earth. What was the cosmonaut's pulse? Temperature? What were the altitudes of the spaceship? Electronic communications received the answers to these questions via radio, radar, and telemetry. German Titov was the second Soviet cosmonaut, who on August 6, 1961, rode the spaceship Vostok 2 seventeen times around the Earth in 25 hours and 11 minutes. German Titov communicated with the Earth by radiophone. He travelled at altitudes ranging from 178 to 244 km.: |

1 | Transmission lines belong to the basic parts of the technological sphere of modern communication. In this sphere there operate different types of energy transmission lines. They differ in length, construction, and cost. Among different types of transmission lines compressed gas-insulated ones have a number of advantages. Their main advantages are simplicity of construction and comparatively low cost. The gas-insulated lines include a number of phase conductors and each of them is placed inside a tube. In the technological sphere there operate different types of ________.: |

Lines used for energy transmission may be classed into the following three types: overhead, indoor and underground. Naturally, these types are different in construction and in the elements they are made of. As for overhead lines, they include line conductors, insulators and supports. Indoor lines include conductors, cords and buses. The conductors in indoor lines may include one wire or a combination of wires not insulated from one another. Underground lines mostly used in ________.: |

1 | The losses of a system including compressed gas-insulated transmission are rather low; they are considerably lower than those of cable transmission. Besides, unlike cables, compressed gas-insulated transmission system can be designed for ultra-high frequencies. The next advantage is that there is no external electric field in the system. As for the shunt capacitance, it is considerably less for a gas-insulated line than for a cable. A gas-insulated line can thus transmit power over larger distances than cable lines. The losses of a system are considerably lower than those of ________.: |
