46. lappuse - Union are : a) to maintain and extend international cooperation for the improvement and rational use of telecommunication of all kinds ; b) to promote the development of technical facilities and their most efficient operation with a view to improving the efficiency of telecommunication services, increasing their usefulness and making them, so far as possible, generally available to the public ; c) to harmonize the actions of nations in the attainment of those common ends.
150. lappuse - Fixed-satellite service. A radiocommunication service between Earth stations at specified fixed points when one or more satellites are used; 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.
150. lappuse - Earth Exploration-Satellite Service. A radiocommunication service between earth stations and one or more space stations, which may include links between space stations in which: (1) Information relating to the characteristics of the Earth and its natural phenomena is obtained from active sensors or passive sensors on earth satellites; (2) Similar information is collected from air-borne or earth-based platforms; (3) Such information may be distributed to earth stations within the system concerned;...
149. lappuse - Assigned Frequency Band. The frequency band within which the emission of a station is authorized; the width of the band equals the necessary bandwidth plus twice the absolute value of the frequency tolerance.
150. lappuse - Harmful interference. Any emission, radiation or induction which endangers the functioning of a radionavigation service or of other safety services or seriously degrades, obstructs or repeatedly interrupts a radiocommunication service operating in accordance with this chapter.
152. lappuse - A system of telecommunication which Is concerned in any process providing transmission and reproduction at a distance of documentary matter, such as written or printed matter or fixed Images, or the reproduction at a distance of any kind of information in such form.
52. lappuse - In using frequency bands for space radio services Members shall bear in mind that radio frequencies and the geostationary satellite orbit are limited natural resources and that they must be used efficiently and economically, in conformity with the provisions of the Radio Regulations, so that countries or groups of countries may have equitable access to both...
152. lappuse - ... any transmission, emission or reception of signs, signals, writings, images, and sounds or intelligence of any nature by wire, radio, optical, or other electromagnetic systems.
