RES507 – 326 – MOD RESOLUTION 507 (REV.WRC-15) Establishment of agreements and associated plans for the broadcasting-satellite service1 The World Radiocommunication Conference (Geneva, 2015), considering a) that it is important to make the best possible use of the geostationary-satellite orbit and of the frequency bands allocated to the broadcasting-satellite service; b) that the great number of receiving installations using such directional antennas as could be set up for a broadcasting-satellite service may be an obstacle to changing the location of space stations in that service on the geostationary-satellite orbit, as of the date of their being brought into use; c) that satellite broadcasts may create harmful interference over a large area of the Earth’s surface; d) that the other services with allocations in the same frequency band need to use the frequency band before the broadcasting-satellite service is set up, resolves 1 that stations in the broadcasting-satellite service shall be established and operated in accordance with agreements and associated plans adopted by world or regional radiocommunication conferences, as the case may be, in which all the administrations concerned and the administrations whose services are liable to be affected may participate; 2 that during the period before the entry into force of such agreements and associated plans the administrations and the Radiocommunication Bureau shall apply the procedure contained in Resolution 33 (Rev.WRC-15), invites the Council to keep under review the question of world radiocommunication conferences, and/or regional radiocommunication conferences, as required, with a view to fixing suitable dates, places and agenda. _______________ 1 This Resolution does not apply to the frequency band 21.4-22 GHz.
