SIST EN 301 427 V2.1.1:2016
(Main)Satellite Earth Stations and Systems (SES) - Harmonised Standard for low data rate Mobile satellite Earth Stations (MESs) except aeronautical mobile satellite earth stations, operating in the 11/12/14 GHz frequency bands covering the essential requirements of article 3.2 of the Directive 2014/53/EU
Satellite Earth Stations and Systems (SES) - Harmonised Standard for low data rate Mobile satellite Earth Stations (MESs) except aeronautical mobile satellite earth stations, operating in the 11/12/14 GHz frequency bands covering the essential requirements of article 3.2 of the Directive 2014/53/EU
The present document applies to Mobile Earth Stations (MES), except aeronautical mobile earth stations, which have
the following characteristics:
• The MES are operating in one or more frequency ranges of the Fixed Satellite Service (FSS):
- 10,70 GHz to 11,70 GHz (space to earth);
- 12,50 GHz to 12,75 GHz (space to earth);
- 14,00 GHz to 14,25 GHz (earth to space).
Because the transmissions from the MES to the Satellite in the 14,00 GHz to 14,25 GHz band fall under a secondary
allocation, the transmissions should not cause harmful interference to primary services (e.g. the Fixed Satellite Service
(FSS)) and at the same time cannot claim protection from harmful interference from those services.
• The MES may be either:
- a Land Mobile Earth Station (LMES) radio equipment; and/or
- a Maritime Mobile Earth Station (MMES) radio equipment not providing those distress and safety
functions required by the International Maritime Organization (IMO).
• These LMESs could be either vehicle mounted or portable equipment.
• These MMESs are installable equipment on ships.
• The MES could consist of a number of modules including a keyboard interface to the user.
• The MES use linear polarization.
• The MES operate through a geostationary satellite at least 3° away from any other geostationary satellite
operating in the same frequency band and covering the same area.
• The antenna of the MES may be omnidirectional or directional with a means of tracking the satellite.
• The MES are operating as part of a satellite network used for the distribution and/or exchange of information
between users.
• The MES are 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 MES with its ancillary equipment and its various terrestrial ports, and when
operated within the boundary limits of the operational environmental profile declared by the manufacturer.
The present document is intended to cover the provisions of Directive 2014/53/EU [3] (RE Directive) article 3.2, which
states that "… radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio
spectrum in order to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the RE Directive [3] may apply to equipment within the scope of the present document.
NOTE: A list of such ENs is included on the ETSI web site.
Satelitske zemeljske postaje in sistemi (SES) - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU, za mobilne satelitske zemeljske postaje (MES) z nizkimi hitrostmi prenosa podatkov, razen za aeronavtične mobilne satelitske zemeljske postaje, ki obratujejo v frekvenčnih pasovih 11/12/14 GHz
Ta dokument se uporablja za mobilne zemeljske postaje (MES), razen za aeronavtične mobilne zemeljske postaje, z naslednjimi značilnostmi:
• Mobilne zemeljske postaje obratujejo v enem ali več frekvenčnih območjih fiksne satelitske storitve (FSS):
– od 10,70 do 11,70 GHz (vesolje–Zemlja);
– od 12,50 do 12,75 GHz (vesolje–Zemlja);
– od 14,00 do 14,25 GHz (Zemlja–vesolje);
Ker je pas od 14,00 do 14,25 GHz sekundarno dodeljen za prenose od mobilne zemeljske postaje do satelita, slednji ne bi smeli motiti primarnih storitev (npr. fiksnih satelitskih storitev (FSS)) in hkrati zanje ni mogoče zahtevati zaščite pred škodljivimi motnjami, ki jih povzročajo primarne storitve.
• Mobilna zemeljska postaja je lahko:
– radijska oprema kopenskih mobilnih zemeljskih postaj (LMES) in/ali
– radijska oprema pomorskih mobilnih zemeljskih postaj (MMES), ki ne zagotavlja funkcij za stisko in varnost,
ki jih zahteva Mednarodna pomorska organizacija (IMO).
• Kopenske mobilne zemeljske postaje so lahko nameščene na vozilu ali prenosne.
• Pomorske mobilne zemeljske postaje so nameščene v plovilih.
• Mobilne zemeljske postaje so lahko sestavljene iz več modulov, vključno z vmesnikom s tipkovnico za uporabnika.
• Mobilne zemeljske postaje uporabljajo linearno polarizacijo.
• Mobilne zemeljske postaje delujejo prek geostacionarnega satelita, ki je odmaknjen za vsaj 3° od kateregakoli drugega geostacionarnega satelita, ki deluje v istem frekvenčnem pasu in na istem območju.
• Antena mobilne zemeljske postaje je lahko vsesmerna ali usmerjena z možnostjo sledenja satelitu.
• Mobilne zemeljske postaje delujejo kot del satelitskega omrežja, ki se uporablja za distribucijo in/ali izmenjavo informacij med uporabniki.
• Mobilne zemeljske postaje se krmili in spremlja z napravo za krmiljenje omrežja (NCF). Naprava za krmiljenje omrežja ne spada v področje uporabe tega dokumenta.
Ta dokument se uporablja za mobilno zemeljsko postajo s pomožno opremo in različnimi zemeljskimi vrati, ko ta deluje znotraj mejnih vrednosti obratovalnega okoljskega profila, kot ga določi proizvajalec.
Ta dokument zajema določbe člena 3.2 Direktive 2014/53/EU [3] (direktive RE), ki navaja: »/.../ Radijska oprema je izdelana tako, da optimalno uporablja in podpira učinkovito izrabo radijskega spektra, z namenom preprečevanja škodljivega motenja.«
Poleg tega dokumenta se za opremo v področju uporabe tega dokumenta lahko uporabljajo tudi drugi standardi EN, ki določajo tehnične zahteve v zvezi z bistvenimi zahtevami iz drugih delov člena 3 Direktive RE [3].

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio equipment under the RE Directive [3]. The modular structure is shown in ETSI EG 201 399 [i.1].
Figure 1: Void
ETSI
7 ETSI EN 301 427 V2.1.1 (2016-06)
The present document is based on ETSI TBR 027 [i.2].
The requirements have been selected to ensure an adequate level of compatibility with other radio services. The levels,
however, do not cover extreme cases which may occur in any location but with a low probability of occurrence.
The present document may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or broadcast site in the
near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference, or
the interfered part or both.
The present document does not contain any requirement, recommendation or information about the installation of the
MES.
The determination of the parameters of the user earth stations using a given geostationary satellite for the protection of
the spectrum allocated to that satellite, is considered to be under the responsibility of the satellite operator or the
satellite network operators.

Introduction The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to cover all radio equipment under the RE Directive [3]. The modular structure is shown in ETSI EG 201 399 [i.1]. Figure 1: Void SIST EN 301 427 V2.1.1:2016
ETSI ETSI EN 301 427 V2.1.1 (2016-06) 7 The present document is based on ETSI TBR 027 [i.2]. The requirements have been selected to ensure an adequate level of compatibility with other radio services. The levels, however, do not cover extreme cases which may occur in any location but with a low probability of occurrence. The present document may not cover those cases where a potential source of interference which is producing individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or broadcast site in the near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference, or the interfered part or both. The present document does not contain any requirement, recommendation or information about the installation of the MES. The determination of the parameters of the user earth stations using a given geostationary satellite for the protection of the spectrum allocated to that satellite, is considered to be under the responsibility of the satellite operator or the satellite network operators. SIST EN 301 427 V2.1.1:2016
ETSI ETSI EN 301 427 V2.1.1 (2016-06) 8 1 Scope The present document applies to Mobile Earth Stations (MES), except aeronautical mobile earth stations, which have the following characteristics: • The MES are operating in one or more frequency ranges of the Fixed Satellite Service (FSS): - 10,70 GHz to 11,70 GHz (space to earth); - 12,50 GHz to 12,75 GHz (space to earth); - 14,00 GHz to 14,25 GHz (earth to space). Because the transmissions from the MES to the Satellite in the 14,00 GHz to 14,25 GHz band fall under a secondary allocation, the transmissions should not cause harmful interference to primary services (e.g. the Fixed Satellite Service (FSS)) and at the same time cannot claim protection from harmful interference from those services. • The MES may be either:
- a Land Mobile Earth Station (LMES) radio equipment; and/or - a Maritime Mobile Earth Station (MMES) radio equipment not providing those distress and safety functions required by the International Maritime Organization (IMO). • These LMESs could be either vehicle mounted or portable equipment. • These MMESs are installable equipment on ships. • The MES could consist of a number of modules including a keyboard interface to the user. • The MES use linear polarization. • The MES operate through a geostationary satellite at least 3° away from any other geostationary satellite operating in the same frequency band and covering the same area. • The antenna of the MES may be omnidirectional or directional with a means of tracking the satellite. • The MES are operating as part of a satellite network used for the distribution and/or exchange of information between users. • The MES are 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 MES with its ancillary equipment and its various terrestrial ports, and when operated within the boundary limits of the operational environmental profile declared by the manufacturer.
The present document is intended to cover the provisions of Directive 2014/53/EU [3] (RE Directive) article 3.2, which states that "… radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference". In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the RE Directive [3] may apply to equipment within the scope of the present document. NOTE: A list of such ENs is included on the ETSI web site. SIST EN 301 427 V2.1.1:2016
