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 Final draft ETSI EN 302 977 V1.1.1 (2009-10)
• 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 must 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 1999/5/EC [1] (R&TTE Directive) article 3.2,
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as 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 1999/5/EC [1] (R&TTE 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/.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in Directive 1999/5/EC [1] and the following
apply:
ancillary equipment: equipment used in connection with a VMES is considered as ancillary if the three following
conditions are met:
• the equipment is intended for use in conjunction with the VMES to provide additional operational and/or
control features (e.g. to extend control to another position or location); and
• the equipment cannot be used on a stand alone basis, to provide user functions independently of the VMES;
and
• the absence of the equipment does not inhibit the operation of the VMES.
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
antenna controller: equipment used to maintain antenna stabilization and tracking accuracy based on inputs from the

ETSI
10 Final draft ETSI EN 302 977 V1.1.1 (2009-10)
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
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 must 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.

internal control channel: control channel which is carried by the VMES network via the same satellite as used for
transmission of user data and within the internal protocol structure of the VMES system
Internally Mounted Equipment (IME): part of the VMES equipment which is installed inside the vehicle and its
connection cables with the EME
NOTE: The IME is usually comprised of:
a) the modem and the IF radio equipment;
b) the interfaces to equipment and services onboard the vehicle.
Optionally the IME may include the following elements (otherwise they will be included in the EME):
c) a Block Down Converter (BDC), which converts the RF signals to intermediate frequencies;

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 V1.1.2 (2010-02)
• 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 must 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 1999/5/EC [1] (R&TTE Directive) article 3.2,
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as 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 1999/5/EC [1] (R&TTE 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/.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in Directive 1999/5/EC [1] and the following
apply:
ancillary equipment: equipment used in connection with a VMES is considered as ancillary if the three following
conditions are met:
• the equipment is intended for use in conjunction with the VMES to provide additional operational and/or
control features (e.g. to extend control to another position or location); and
• the equipment cannot be used on a stand alone basis, to provide user functions independently of the VMES;
and
• the absence of the equipment does not inhibit the operation of the VMES.
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
antenna controller: equipment used to maintain antenna stabilization and tracking accuracy based on inputs from the

ETSI
10 ETSI EN 302 977 V1.1.2 (2010-02)
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
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 must 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.
ETSI
11 ETSI EN 302 977 V1.1.2 (2010-02)

internal control channel: control channel which is carried by the VMES network via the same satellite as used for
transmission of user data and within the internal protocol structure of the VMES system
Internally Mounted Equipment (IME): part of the VMES equipment which is installed inside the vehicle and its
connection cables with the EME
NOTE: The IME is usually comprised of:
a) the modem and the IF radio equipment;
b) the interfaces to equipment and services onboard the vehicle.
Optionally the IME may include the following elements (otherwise they will be included in the EME):
c) a Block Down Converter (BDC), which converts the RF signals to intermediate frequencies;

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 and telecommunications terminal equipment within the scope of the R&TTE Directive [1]. The modular structure is shown in EG 201 399 [i.2]. SIST EN 302 977 V1.1.2:2010

ETSI ETSI EN 302 977 V1.1.2 (2010-02) 7 1 Scope The present document applies to Earth Stations located on board Vehicles, which have the following characteristics. In-vehicle Services Interface Stabilization & Tracking mechanism AntennaEnclosure / RadomeControl and Monitoring Function Antenna Controller ModemExternal mounted equipment (EME) Internally mounted equipment (IME) Externally or internally mounted equipment LNA BDC HPA BUC RadioAntenna Control Facility Interface
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 V1.1.2 (2010-02) 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 must 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 1999/5/EC [1] (R&TTE Directive) article 3.2, which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as 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 1999/5/EC [1] (R&TTE 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 References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accepted that it will be possible to use all future changes of the referenced document for the purposes of the referring document; - for informative references. Referenced documents which are not found to be publicly available in the expected location might be found at http://docbox.etsi.org/Reference.

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 must 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. SIST EN 302 977 V1.1.2:2010
