The present document applies to Earth Stations located on board Vessels (ESVs) which have the following characteristics:
" The ESV is comprised of all the equipment, electrical and mechanical, from the antenna itself to the in-terface with other communications equipment on board (usually referred to as the terrestrial interface).
" The ESV transmits in the frequency range from 14,00 GHz to 14,50 GHz allocated to the Fixed Satellite Services (FSS) (earth to space).
" The ESV receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in the bands allocated to the Fixed Satellite Services (FSS) (space to earth), depending on the ITU Region where the ESV is located.
" The ESV uses linear polarization.
" The ESV operates through a geostationary satellite at least 2° to 3° away from any other geostationary satellite operating in the same frequency band and covering the same area.
NOTE 1: The satellite spacing is mainly equal to 3° in ITU Regions 1 and 3 and 2° in ITU Region 2.
The ESV transmits at elevations greater or equal to the minimum elevation angle declared by the applicant.
" The ESV antenna diameter is not smaller than 0,6 m.
NOTE 2: Operation within 125 km of non CEPT countries with antenna diameter smaller than 1,2 m may be subject to specific agreement with concerned administrations as stated in ITU-R Resolution 902 (WRC 03).
" The ESV is designed for transmission and reception of radio communications signals in accordance with any of the frequency bands specified above.
" The ESV is usually designed for unattended operation.
" The ESV is operating as part of a satellite network (e.g. star, mesh or point to point) used for the distri-bution and/or exchange of information between users.
" The ESV is controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the present document.
The present document applies to the ESV with its ancillary equipment and its various telecommunication ports, and when operated within the boundary limits of the operational environmental profile declared by the applicant and when installed as required by the applicant by declaration or in the user documentation.
The present document is intended to cover the provisions of Directive 2014/53/EU [9] (RE Directive) article 3.2, which states that ". radio equipment shall be so constructed that it both effectively uses and supports the effi-cient use of radio spectrum in order to avoid harmful interference".
The present document incorporates the technical limitations listed in annex 2 of ITU-R Resolution 902 (WRC 03) [i.2].
NOTE 3: According to ITU-R Resolution 902 (WRC 03), any transmission from ESVs within the 125 km minimum distance of each country where the ESV transmit frequency band is used by the Fixed Service will be subject to the prior agreement of the concerned administration(s) or to the relevant ECC Decision and may specify additional operational requirements.
In addition to the present document, other ENs that specify technical requirements in respect of essential re-quirements under other parts of article 3 of the Directive 2014/53 [9] (RE Directive) may apply to equipment within the scope of the present document.
