Satelitske zemeljske postaje in sistemi (SES) - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU, za zemeljske postaje na vozilih (VMES), delujoče v frekvenčnih pasovih 11/12/14 GHz
Ta dokument se uporablja za zemeljske postaje na vozilih z naslednjimi značilnostmi:
Zemeljska postaja na vozilu lahko oddaja in sprejema podatke, ko se vozilo premika ali ko je
na mestu.
• Zemeljska postaja na vozilu deluje v vozilu na kolesih ali gosenicah, pri čemer lahko pride do občasnih motenj in prekinitev v satelitski povezavi.
• Zemeljska postaja na vozilu deluje kot del satelitskega omrežja (npr. zvezdnega, mrežnega ali od točke do točke), ki se uporablja za distribucijo in/ali izmenjavo informacij.
• Zemeljska postaja na vozilu je sestavljena iz vse opreme, električne in mehanske, od same antene do vmesnikov z drugo komunikacijsko opremo v vozilu (običajno se imenujejo zemeljski vmesniki).
• Zemeljska postaja na vozilu oddaja prek ene nosilne frekvence v frekvenčnem območju od 14,00 do 14,50 GHz – to je pas, ki je med drugimi storitvami dodeljen fiksnim satelitskim storitvam (FSS) (Zemlja–vesolje). Vendar je delovanje zemeljske postaje na vozilu omejeno na spodnjo polovico pasu, v državah, ki so pas dodelile fiksnim storitvam (FS), in njihovi bližini pa na zgornjo polovico. Lokalni predpisi lahko dovolijo delovanje v zgornji polovici pasu.
OPOMBA 1: za namen te specifikacije se modulacija ortogonalnega frekvenčnega multipleksa obravnava kot en nosilec.
• Zemeljska postaja na vozilu sprejema na eni ali več frekvencah v območju od 10,70 do 12,75 GHz v pasovih, ki so dodeljeni fiksnim satelitskim storitvam (FSS) (vesolje–Zemlja) ali radiodifuzijskim satelitskim storitvam (BSS) (vesolje-Zemlja), odvisno od regije Mednarodne telekomunikacijske zveze, v kateri se zemeljska postaja nahaja.
• Zemeljska postaja na vozilu uporablja linearno ali krožno polarizacijo.
• Zemeljska postaja na vozilu deluje prek geostacionarnega satelita (ali skupine skupno nameščenih geostacionarnih satelitov), ki je odmaknjen za vsaj 3° od kateregakoli drugega geostacionarnega satelita, ki deluje v istem frekvenčnem pasu in na istem območju.
OPOMBA 2: razmik med sateliti je lahko manjši od 3°. V teh primerih satelitski operater obvesti zemeljsko postajo na vozilu, ki deluje kot odjemalec, o zahtevah dogovorov za koordinacijo sistemov.
• Zemeljska postaja na vozilu oddaja na višinah, ki so večje ali enake 7° glede na lokalno obzorje.
• Zemeljska postaja na vozilu je izdelana za nenadzorovano delovanje.
• Zemeljska postaja na vozilu je izdelana za mobilno in stacionarno delovanje. V primeru stacionarnega delovanja se mora zemeljska postaja na vozilu varno upravljati in naj ne bi bila dostopna splošni javnosti.
• Zemeljska postaja na vozilu se krmili in spremlja z napravo za krmiljenje antene (ACF). Ta funkcija se lahko
izvaja centralno (npr. za omrežje zemeljskih postaj na vozilih s centralnim vozliščem) ali pa se lahko izvaja v sami zemeljski postaji na vozilu za avtonomno krmiljenje. Naprava za krmiljenje antene ne spada v področje uporabe tega dokumenta.
Ta dokument se uporablja za zemeljsko postajo na vozilu s pomožno opremo in različnimi telekomunikacijskimi vrati, ko ta deluje znotraj mejnih vrednosti obratovalnega okoljskega profila, kot ga določi kandidat, ter ko je nameščena v skladu z zahtevami kandidatove izjave ali v skladu z zahtevami dokumentacije uporabnika.
Ta dokument zajema določbe člena 3.2 Direktive 2014/53/EU [9] (direktive RE), ki navaja: »/.../ Radijska oprema je izdelana tako, da optimalno uporablja in podpira učinkovito izrabo radijskega spektra, z namenom preprečevanja škodljivega motenja.«
OPOMBA 3: obratovalne zahteve določajo nacionalne uprave in ustrezni sklepi Odbora za elektronske komunikacije.
Poleg tega dokumenta se lahko za opremo na področju uporabe tega dokumenta uporabljajo tudi drugi standardi EN, ki določajo tehnične zahteve v zvezi z bistvenimi zahtevami iz drugih delov člena 3 Direktive 2014/53/EU [9].
OPOMBA 4: seznam tovrstnih evropskih standardov je na voljo na spletnem mestu http://www.newapproach.org/.

Figure 1: VMES System Overview
• The VMES may transmit and receive data when the vehicle is in motion and also when the vehicle is
stationary.
• The VMES operates on wheeled or tracked vehicles and, therefore, may be subject to occasional disturbances
and interruptions in the satellite link.
• The VMES 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.
• The VMES is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on a vehicle (usually referred to as the terrestrial interface).
• The VMES transmits on single carrier in the frequency range 14,00 GHz to 14,50 GHz, which is a band
allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. However, operation of
the VMES is intended to be restricted to the lower half of the band in and near those countries that have
allocated Fixed Service (FS) to the upper half. Local regulation may permit operation in the upper half of the
band.
NOTE 1: For the purposes of the present specification, OFDM modulation is considered as a single carrier.
• The VMES receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in bands
allocated to the Fixed Satellite Services (FSS) (space-to-Earth) or the Broadcast Satellite Service (BSS)
(space-to-Earth), depending on the ITU Region where the VMES is located.
• The VMES uses linear or circular polarization.
• The VMES is designed to operate through a geostationary satellite (or a cluster of co-located geostationary
satellites) that is at least 3° away from any other geostationary satellite operating in the same frequencies and
over the same coverage area.
NOTE 2: Satellites may be spaced closer than 3°. In such cases, the satellite operator will inform the VMES client
of the requirements of the system coordination agreements.
ETSI
8 Draft ETSI EN 302 977 V2.1.0 (2016-02)
• The VMES transmits at elevations greater than or equal to 7° relative to the local horizon.
• The VMES is designed for unattended operation.
• The VMES is designed for both mobile and stationary operation. In the case of stationary operation, the
VMES should not be accessible to the general public and operated safely.
• The VMES is controlled and monitored by an Antenna Control Facility (ACF). This function may be
performed centrally (e.g. for a network of VMESs with a central hub) or it could be performed within the
VMES for autonomous control. The ACF is outside the scope of the present document.
The present document applies to the VMES with its ancillary equipment and its various telecommunication ports, and
when operated within the boundary limits of the operational environmental profile as declared by the applicant and
when installed as required by the applicant's 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 efficient use of radio
spectrumin order to avoid harmful interference".
NOTE 3: Operational requirements are defined by national administrations and by relevant ECC Decisions.
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 Directive 2014/53 [9] (RE Directive) may apply to equipment within the scope of
the present document.
NOTE 4: A list of such ENs is included on the web site http://www.newapproach.org/.

NOTE 1: The phrase "the VMES may transmit" means that all the conditions for transmission are satisfied (e.g. in a
state where transmissions are permitted, no failure detected, and the VMES is correctly pointed towards
the satellite).
NOTE 2: The existence of a "Carrier-off" radio state depends on the system of transmission used. For VMESs
designed for continuous transmission mode there may be no "Carrier-off" state.
carrier-on radio state: radio state in which the VMES may transmit and transmits a carrier
Control Channel (CC): channel or channels by which VMESs receive control information from the ACF
EIRP : maximum e.i.r.p. capability of the VMES as declared by the applicant
max
emissions-disabled radio state: radio state in which the VMES does not emit
NOTE: Examples of cases where the VMES is in this radio state: before system monitoring pass, before the
control channel is received, when a failure is detected, when a VMES is commanded to disable, and when
the VMES is in a location requiring cessation of emissions.
external control channel: control channel which is either:
(i) carried by the VMES network via the same or another satellite, but not within the internal protocol of the
VMES system; or
(ii) carried by any other radio communication system.
Externally Mounted Equipment (EME): that part of the VMES intended to be installed on the outside of the vehicle
(usually the roof), as declared by the applicant, or as indicated in the user documentation
NOTE 1: The EME unit is usually comprised of 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 Amplifier (LNA) which is a device that amplifies, with very low internal noise, the
received signals in the Radio Frequency (RF) band.
c) The stabilization and tracking mechanics that ensure pointing of the antenna main beam towards
the satellite within the required accuracy.
d) The radome for protecting the antenna subsystem, if required for normal operation.
NOTE 2: The LNA could be replaced by an LNB, which includes the block down converter.
Optionally, the EME may include the following elements (otherwise they will be part of the IME):
a) A Block Up Converter (BUC) and High Power Amplifier (HPA) which convert from the
intermediate frequency to RF and amplify the low level RF signals for transmission through the
antenna subsystem.
b) The Antenna Controller Processor.
c) The Control and Monitoring Function.
NOTE 3: 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.
NOTE 4: Certain configurations may include more than one EME per VMES. As for example, the VMES may
have separate transmit and receive antennas or it may have redundant transmit/receive antenna units.

Figure 1: VMES System Overview
• The VMES may transmit and receive data when the vehicle is in motion and also when the vehicle is
stationary.
• The VMES operates on wheeled or tracked vehicles and, therefore, may be subject to occasional disturbances
and interruptions in the satellite link.
• The VMES 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.
• The VMES is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on a vehicle (usually referred to as the terrestrial interface).
• The VMES transmits on single carrier in the frequency range 14,00 GHz to 14,50 GHz, which is a band
allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. However, operation of
the VMES is intended to be restricted to the lower half of the band in and near those countries that have
allocated Fixed Service (FS) to the upper half. Local regulation may permit operation in the upper half of the
band.
NOTE 1: For the purposes of the present specification, OFDM modulation is considered as a single carrier.
• The VMES receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in bands
allocated to the Fixed Satellite Services (FSS) (space-to-Earth) or the Broadcast Satellite Service (BSS)
(space-to-Earth), depending on the ITU Region where the VMES is located.
• The VMES uses linear or circular polarization.
• The VMES is designed to operate through a geostationary satellite (or a cluster of co-located geostationary
satellites) that is at least 3° away from any other geostationary satellite operating in the same frequencies and
over the same coverage area.
NOTE 2: Satellites may be spaced closer than 3°. In such cases, the satellite operator will inform the VMES client
of the requirements of the system coordination agreements.
ETSI
8 ETSI EN 302 977 V2.1.1 (2016-06)
• The VMES transmits at elevations greater than or equal to 7° relative to the local horizon.
• The VMES is designed for unattended operation.
• The VMES is designed for both mobile and stationary operation. In the case of stationary operation, the
VMES should not be accessible to the general public and operated safely.
• The VMES is controlled and monitored by an Antenna Control Facility (ACF). This function may be
performed centrally (e.g. for a network of VMESs with a central hub) or it could be performed within the
VMES for autonomous control. The ACF is outside the scope of the present document.
The present document applies to the VMES with its ancillary equipment and its various telecommunication ports, and
when operated within the boundary limits of the operational environmental profile as declared by the applicant and
when installed as required by the applicant's 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 efficient use of radio
spectrumin order to avoid harmful interference".
NOTE 3: Operational requirements are defined by national administrations and by relevant ECC Decisions.
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 Directive 2014/53/EU [9] (RE Directive) may apply to equipment within the scope
of the present document.
NOTE 4: A list of such ENs is included on the web site http://www.newapproach.org/.

Figure 1: VMES System Overview • The VMES may transmit and receive data when the vehicle is in motion and also when the vehicle is stationary. • The VMES operates on wheeled or tracked vehicles and, therefore, may be subject to occasional disturbances and interruptions in the satellite link. • The VMES 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. • The VMES is comprised of all the equipment, electrical and mechanical, from the antenna itself to the interface with other communications equipment on a vehicle (usually referred to as the terrestrial interface). • The VMES transmits on single carrier in the frequency range 14,00 GHz to 14,50 GHz, which is a band allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. However, operation of the VMES is intended to be restricted to the lower half of the band in and near those countries that have allocated Fixed Service (FS) to the upper half. Local regulation may permit operation in the upper half of the band. NOTE 1: For the purposes of the present specification, OFDM modulation is considered as a single carrier. • The VMES receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in bands allocated to the Fixed Satellite Services (FSS) (space-to-Earth) or the Broadcast Satellite Service (BSS) (space-to-Earth), depending on the ITU Region where the VMES is located. • The VMES uses linear or circular polarization. • The VMES is designed to operate through a geostationary satellite (or a cluster of co-located geostationary satellites) that is at least 3° away from any other geostationary satellite operating in the same frequencies and over the same coverage area. NOTE 2: Satellites may be spaced closer than 3°. In such cases, the satellite operator will inform the VMES client of the requirements of the system coordination agreements.

ETSI ETSI EN 302 977 V2.1.1 (2016-06) 8 • The VMES transmits at elevations greater than or equal to 7° relative to the local horizon. • The VMES is designed for unattended operation. • The VMES is designed for both mobile and stationary operation. In the case of stationary operation, the VMES should not be accessible to the general public and operated safely. • The VMES is controlled and monitored by an Antenna Control Facility (ACF). This function may be performed centrally (e.g. for a network of VMESs with a central hub) or it could be performed within the VMES for autonomous control. The ACF is outside the scope of the present document. The present document applies to the VMES with its ancillary equipment and its various telecommunication ports, and when operated within the boundary limits of the operational environmental profile as declared by the applicant and when installed as required by the applicant's 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 efficient use of radio spectrumin order to avoid harmful interference". NOTE 3: Operational requirements are defined by national administrations and by relevant ECC Decisions. 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 Directive 2014/53/EU [9] (RE Directive) may apply to equipment within the scope of the present document. NOTE 4: A list of such ENs is included on the web site http://www.newapproach.org/. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

Antenna Control Facility (ACF): set of functional entities that, at system level, monitor and control the correct operation of the VMES and, if appropriate, all of the VMESs in a network SIST EN 302 977 V2.1.1:2016
ETSI ETSI EN 302 977 V2.1.1 (2016-06) 10 antenna controller: equipment used to maintain antenna stabilization and tracking accuracy based on inputs from the Control and Monitoring Function applicant: manufacturer or his authorized representative within the European Community or the person responsible for placing the apparatus on the market carrier-off radio state: radio state in which the VMES may transmit and does not transmit any carrier NOTE 1: The phrase "the VMES may transmit" means that all the conditions for transmission are satisfied (e.g. in a state where transmissions are permitted, no failure detected, and the VMES is correctly pointed towards the satellite). NOTE 2: The existence of a "Carrier-off" radio state depends on the system of transmission used. For VMESs designed for continuous transmission mode there may be no "Carrier-off" state. carrier-on radio state: radio state in which the VMES may transmit and transmits a carrier Control Channel (CC): channel or channels by which VMESs receive control information from the ACF EIRPmax: maximum e.i.r.p. capability of the VMES as declared by the applicant emissions-disabled radio state: radio state in which the VMES does not emit NOTE: Examples of cases where the VMES is in this radio state: before system monitoring pass, before the control channel is received, when a failure is detected, when a VMES is commanded to disable, and when the VMES is in a location requiring cessation of emissions. external control channel: control channel which is either: (i) carried by the VMES network via the same or another satellite, but not within the internal protocol of the VMES system; or (ii) carried by any other radio communication system. external response channel: response channel which is either: (i) carried by the VMES network via the same or another satellite, but not within the internal protocol of the VMES system; or (ii) carried by any other radio communication system. Externally Mounted Equipment (EME): that part of the VMES intended to be installed on the outside of the vehicle (usually the roof), as declared by the applicant, or as indicated in the user documentation NOTE 1: The EME unit is usually comprised of 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 Amplifier (LNA) which is a device that amplifies, with very low internal noise, the received signals in the Radio Frequency (RF) band. c) The stabilization and tracking mechanics that ensure pointing of the antenna main beam towards the satellite within the required accuracy. d) The radome for protecting the antenna subsystem, if required for normal operation. NOTE 2: The LNA could be replaced by an LNB, which includes the block down converter. Optionally, the EME may include the following elements (otherwise they will be part of the IME): a) A Block Up Converter (BUC) and High Power Amplifier (HPA) which convert from the intermediate frequency to RF and amplify the low level RF signals for transmission through the antenna subsystem. b) The Antenna Controller Processor. c) The Control and Monitoring Function.
