Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under the Council Directive 98/34/EC [5] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulation.
The present document, together with EN 301 843-1 [1], is intended to become a Harmonized Standard, the reference of
which will be published in the Official Journal of the European Communities referencing the Council Directive on the
approximation of the laws of the Member States relating to electromagnetic compatibility ("the EMC Directive")
(89/336/EEC [3] as amended), and Directive 1999/5/EC of the European Parliament and of the Council of 9 March
1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity
(the "R&TTE Directive" [2]).
EN 301 843-1 [1] is based upon the standard for marine navigational equipment EN 60945 [4] particularly clauses 9
(Electromagnetic emission) and 10 (Immunity to electromagnetic environment).
The present document is part 6 of a multi-part deliverable. Full details of the entire series can be found in part 1 [1].

National transposition dates
Date of adoption of this EN: 20 January 2006
Date of latest announcement of this EN (doa): 30 April 2006
Date of latest publication of new National Standard

Date of withdrawal of any conflicting National Standard (dow): 31 October 2007

1 Scope
The present document together with EN 301 843-1 [1], covers the assessment of Earth Stations on board Vessels
(ESVs) transmitting above 3 GHz in the Fixed Satellite Service (FSS) as defined in annex A and ancillary equipment in
respect of ElectroMagnetic Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of Earth Stations on board
Vessels are not included in the present document. Such technical specifications are found in the related product
standards for the effective use of the radio spectrum.
The present document specifies the applicable test conditions, performance assessment, and performance criteria for
Earth Stations on board Vessels and the associated ancillary equipment.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and EN 301 843-1 [1], the provisions of the present document take precedence.
The electromagnetic environment used in the present document to develop the technical specifications encompasses the
electromagnetic environment onboard ships as identified in EN 60945 [4].

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in EN 301 843-1 [1] and the following apply:
above-deck unit: part of the ESV intended to be installed above deck, as declared by the manufacturer, or as indicated
in the user documentation
NOTE 1: The above-deck unit usually comprises the following main parts:
a) the antenna sub-system which converts the incident radiation field into a guided wave and
vice versa;
b) the Low Noise Block (LNB) down converter, which is a device that amplifies, with very low
internal noise, the received signals in the Radio Frequency (RF) band and converts them to
intermediate frequencies;
c) the up-converter and the power amplifier which convert from the intermediate frequency to RF and
amplify the low level RF signals for transmission through the antenna subsystem;
d) the stabilization and tracking subsystems that ensure pointing of the antenna main beam towards
the satellite within the required accuracy.
NOTE 2: The installation equipment (means of attachment) is outside the scope of the present document. However,
the antenna structures and other components directly mounted on the antenna and forming an integral part
of it, are subject to the specifications of the present document.
below-deck unit: is composed of that part of the ESV equipment which is not part of the above-deck unit. This unit is
installed inside the vessel and is connected to the above-deck unit. The connection cable between the above and
below-deck units is considered part of the below-deck unit
carrier-off state: ESV is in this state when it is authorized by the Centralized Control and Monitoring Functions
(CCMF) to transmit, but when it does not transmit any signal
NOTE: The existence of a carrier-off state depends on the system of transmission used. For ESV designed for
continuous transmission mode there may be no carrier-off state.
carrier-on state: ESV is in this state when it is authorized by the CCMF to transmit and when it transmits a signal
transmission enabled state: ESV is in this state when it is authorized by the CCMF to transmit
transmission disabled state: ESV is in this state when it is not authorized by the CCMF to transmit

4 Test conditions
4.1 General
For the purposes of the present document, the test conditions of EN 301 843-1 [1], clause 4, shall apply as appropriate.
Further product type related test conditions for Earth Stations on board Vessels are specified in the present document.
For emission and immunity tests the normal test modulation, test arrangements, etc., as specified in the present
document, clauses 4.1 to 4.5 shall apply.
For Earth Stations on board Vessels with or without ancillary equipment, and/or various telecommunication ports, the
number of test configurations shall be determined. The assessment shall include sufficient representative configurations
of the ESV to adequately exercise the equipment. These configurations shall be recorded in the test report.
In the following clauses, the Equipment Under Test (EUT) is an ESV with the selected configuration of ancillary
equipment.
4.2 Arrangements for test signals
The provisions of EN 301 843-1 [1], clause 4.2 shall apply with the following modifications.
In order to measure the unwanted emissions and electromagnetic immunity under operational conditions, the following
arrangements shall be provided by the manufacturer:
a) the specific test equipment and/or procedures to put the ESV terminal in its normal operating mode, and
providing the ESV with a receive signal to emulate the operational conditions of reception. This equipment
shall control the EUT, when it is capable of transmission, so that it switches between the transmission
disabled, carrier-on and carrier-off states;
b) the specific Quality of Transmission Measurement Apparatus (QTMA). The QTMA shall also monitor and
record the stability of the antenna tracking during testing.
For the measurement of the quality of transmission a communications link shall be established and the wanted input
signal shall be applied to the Radio Frequency (RF) input of the receiver via the antenna.
4.2.1 Arrangements for test signals at the input of the transmitter
The provisions of EN 301 843-1 [1], clause 4.2.1 shall apply.
4.2.2 Arrangements for test signals at the output of the transmitter
The provisions of EN 301 843-1 [1], clause 4.2.2 shall apply.
4.2.3 Arrangements for test signals at the input of the receiver
The provisions of EN 301 843-1 [1], clause 4.2.3 shall apply with the following modification.
For tests on the receiver, due to the fact that for satellite earth stations the receive margin is considerably lower tha
