Foreword
This draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee Satellite Earth
Stations and Systems (SES), and is now submitted for the combined Public Enquiry and Vote phase of the ETSI
Standardisation Request deliverable Approval Procedure (SRdAP).
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.5] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.8].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive and associated
EFTA regulations.
Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa

1 Scope
The present document specifies technical characteristics and methods of measurements for 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
interface 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 in 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 defined for its intended
use.
• The ESV antenna diameter is not smaller than 0,6 m.
NOTE 2: Operation within 125 km of non-CEPT countries is subject to specific agreement with concerned
administrations as stated in ITU-R Resolution 902 (Rev. WRC-23). Decision ECC(05)10 [i.9] applies
for CEPT countries.
• 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
distribution 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 defined for its intended use
including all equipment as brought to the market.
The present document incorporates the technical limitations listed in annex 2 of ITU Radio Regulations
Resolution 902 (Rev. WRC-23) [9].
NOTE 3: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.8] (RE Directive) is given in annex A.
