A radio that can be automatically controlled by electronic devices and that requires little or no human intervention.
Industry:Telecommunications
A radio wave that is propagated by reflection from a place of abrupt change in the dielectric constant, or its gradient, in the troposphere. Note: In some cases, a ground wave may be so altered that new components appear to arise from reflection in regions of rapidly changing dielectric constant. When these components are distinguishable from the other components, they are called "tropospheric waves. "
Industry:Telecommunications
A radio wave that travels upward from the antenna. Note: A sky wave may be reflected to Earth by the ionosphere.
Industry:Telecommunications
A radiocommunication service between Earth stations and one or more space stations, which may include links between space stations, in which: information relating to the characteristics of the Earth and its natural phenomena is obtained from active sensors or passive sensors on Earth satellites; similar information is collected from airborne or Earth-based platforms; such information may be distributed to Earth stations within the system concerned; platform interrogation may be included. This service may also include feeder links necessary for its operation.
Industry:Telecommunications
A radiocommunication service between Earth stations at given positions when one or more satellites are used; the given position may be a specified fixed point or any fixed point within specified areas; in some cases this service includes satellite-to-satellite links, which may also be effected in the inter-satellite service, the fixed-satellite service may also include feeder links for other space radiocommunication services. 2. A radiocommunication service between Earth stations at given positions when one or more satellites are used; the given position may be a specified fixed point or any fixed point within specified areas; in some cases this service includes satellite-to-satellite links, which may also be operated in the inter-satellite service; the fixed-satellite service may also include feeder links of other space radiocommunication services.
Industry:Telecommunications
A radiocommunication service between mobile and land stations, or between mobile stations.
Industry:Telecommunications
A radiocommunication service between specified fixed points provided primarily for the safety of air navigation and for the regular, efficient and economical operation of air transport.
Industry:Telecommunications
A radiocommunication service between specified fixed points.
Industry:Telecommunications
A radiocommunication service concerned exclusively with the operation of spacecraft, in particular space tracking, space telemetry and space telecommand. These functions will normally be provided within the service in which the space station is operating.
Industry:Telecommunications
A radiocommunication service for scientific, technical and other purposes, providing the transmission of specified frequencies, time signals, or both, of stated high precision, intended for general reception.
