Page 36 - 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.
Page 54 - MHz, assignments may be made to television stations using frequency modulation in the broadcasting-satellite service subject to agreement between the administrations concerned and those having services, operating in accordance with the Table, which may be affected (see Resolutions 33 (Rev.WRC-97) and 507). Such stations shall not produce a power flux-density in excess of the value - 129 dB(W'm2) for angles of arrival less than 20" (see Recommendation 705) within the territories of other countries...
Page 55 - ... above the horizontal plane; -150+(8-5)/2 dB(W/m2) in any 4 kHz band for angles of arrival 8 (in degrees) between 5 and 25 degrees above the horizontal plane; and -140 dB(W/m2) in any 4 kHz band for angles of arrival between 25 and 90...
Page 36 - ... the inter-satellite service; — for connection between one or more earth stations at specified fixed points and satellites used for a service other than the fixed-satellite service (for example, the mobile-satellite service, broadcasting-satellite service, etc.).
Page 37 - Service. A radiocommunication service in which signals transmitted or retransmitted by space stations are intended for direct reception by the general public. NOTE: In the broadcasting-satellite service, the term direct reception shall encompass both individual reception and community reception.
Page 37 - Community Reception (in the broadcasting-satellite service). The reception of emissions from a space station in the broadcasting-satellite service by receiving equipment, which in some cases may be complex and have antennae larger than those for individual reception, and intended for use: (1) by a group of the general public at one location; or (2) through a distribution system covering a limited area.
