1 Scope
The present document together with ETSI 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 ETSI 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 on board ships as identified in IEC EN 60945 [i.2].
NOTE: The relationship between the present document and essential requirements of article 3.1b of Directive
2014/53/EU [i.1] is given in annex A.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI 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
NOTE: 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 disabled state: ESV is in this state when it is not authorized by the CCMF to transmit
transmission enabled state: ESV is in this state when it is authorized by the CCMF to transmit

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 disabled state: ESV is in this state when it is not authorized by the CCMF to transmit
transmission enabled state: ESV is in this state when it is authorized by the CCMF to transmit
