Figure 1: ESOMP System Overview
• The ESOMP is designed for both mobile and stationary operation.
• The ESOMP operates on various mobile platforms such as trains, maritime vessels, aircraft and other vehicles
and, therefore, may be subject to occasional disturbances and interruptions in the satellite link.
• The ESOMP 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 ESOMP is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on a mobile platform (usually referred to as the terrestrial
interface).
• The transmit and receive frequencies are shown in table 1.
Table 1: Frequency bands
Frequency Bands/frequencies
(GHz)
Transmit (Earth-to-space) 27,50 to 30,00
Receive (space-to-Earth) 17,30 to 20,20

• The ESOMP transmits within the frequency range from 27,50 GHz to 30,00 GHz, which is a band allocated to
the Fixed Satellite Services (FSS) (Earth-to-space) among other services. However, operation of the ESOMP is
intended to be restricted to the frequency range 29,50 GHz to 30,00 GHz in and near those countries that have
allocated Fixed Service (FS) to the other frequency ranges. Local regulation may permit operation in these
frequency ranges.
• The ESOMP receives in one or more frequencies within the range from 17,30 GHz to 20,20 GHz (FSS).
• The ESOMP uses linear or circular polarization.
• The ESOMP operates through a geostationary satellite (or a cluster of co-located geostationary satellites) that
is at least 2° away from any other geostationary satellite operating in the same frequencies and over the same
coverage area.
NOTE 1: ESOMPs may operate with satellites that are more closely spaced than 2° with additional operational
constraints that are beyond the scope of the present document.
ETSI
10 Final draft ETSI EN 303 978 V1.1.1 (2012-12)
• The ESOMP is designed for unattended operation.
• The ESOMP is controlled and monitored by a Network Control Facility (NCF). This function may be
performed centrally (e.g. for a network of ESOMPs with a central hub) or it could be performed within the
ESOMP for autonomous control. The NCF is outside the scope of the present document.
The present document applies to the ESOMP 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 [i.2] (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 2: 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 [i.2] (R&TTE Directive) may apply to equipment within the
scope of the present document.
NOTE 3: A list of such ENs is included on the web site http://www.newapproach.org/.

Figure 1: ESOMP System Overview
• The ESOMP is designed for both mobile and stationary operation.
• The ESOMP operates on various mobile platforms such as trains, maritime vessels, aircraft and other vehicles
and, therefore, may be subject to occasional disturbances and interruptions in the satellite link.
• The ESOMP 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 ESOMP is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on a mobile platform (usually referred to as the terrestrial
interface).
• The transmit and receive frequencies are shown in table 1.
Table 1: Frequency bands
Frequency Bands/frequencies
(GHz)
Transmit (Earth-to-space) 27,50 to 30,00
Receive (space-to-Earth) 17,30 to 20,20

• The ESOMP transmits within the frequency range from 27,50 GHz to 30,00 GHz, which is a band allocated to
the Fixed Satellite Services (FSS) (Earth-to-space) among other services. However, operation of the ESOMP is
intended to be restricted to the frequency range 29,50 GHz to 30,00 GHz in and near those countries that have
allocated Fixed Service (FS) to the other frequency ranges. Local regulation may permit operation in these
frequency ranges.
• The ESOMP receives in one or more frequencies within the range from 17,30 GHz to 20,20 GHz (FSS).
• The ESOMP uses linear or circular polarization.
• The ESOMP operates through a geostationary satellite (or a cluster of co-located geostationary satellites) that
is at least 2° away from any other geostationary satellite operating in the same frequencies and over the same
coverage area.
NOTE 1: ESOMPs may operate with satellites that are more closely spaced than 2° with additional operational
constraints that are beyond the scope of the present document.
ETSI
10 ETSI EN 303 978 V1.1.2 (2013-02)
• The ESOMP is designed for unattended operation.
• The ESOMP is controlled and monitored by a Network Control Facility (NCF). This function may be
performed centrally (e.g. for a network of ESOMPs with a central hub) or it could be performed within the
ESOMP for autonomous control. The NCF is outside the scope of the present document.
The present document applies to the ESOMP 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 [i.2] (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 2: 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 [i.2] (R&TTE Directive) may apply to equipment within the
scope of the present document.
NOTE 3: A list of such ENs is included on the web site http://www.newapproach.org/.

ETSI ETSI EN 303 978 V1.1.2 (2013-02) 9 1 Scope The present document applies to Earth Stations on Mobile Platforms (ESOMP), which have the following characteristics. Service Interface Stabilization & Tracking mechanism AntennaEnclosure / RadomeControl and Monitoring Function Antenna Controller ModemLNA BDC HPA BUC RadioAntenna Control Facility Interface
Figure 1: ESOMP System Overview • The ESOMP is designed for both mobile and stationary operation. • The ESOMP operates on various mobile platforms such as trains, maritime vessels, aircraft and other vehicles and, therefore, may be subject to occasional disturbances and interruptions in the satellite link. • The ESOMP 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 ESOMP is comprised of all the equipment, electrical and mechanical, from the antenna itself to the interface with other communications equipment on a mobile platform (usually referred to as the terrestrial interface). • The transmit and receive frequencies are shown in table 1. Table 1: Frequency bands
Frequency Bands/frequencies (GHz) Transmit (Earth-to-space) 27,50 to 30,00 Receive (space-to-Earth) 17,30 to 20,20
• The ESOMP transmits within the frequency range from 27,50 GHz to 30,00 GHz, which is a band allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. However, operation of the ESOMP is intended to be restricted to the frequency range 29,50 GHz to 30,00 GHz in and near those countries that have allocated Fixed Service (FS) to the other frequency ranges. Local regulation may permit operation in these frequency ranges. • The ESOMP receives in one or more frequencies within the range from 17,30 GHz to 20,20 GHz (FSS). • The ESOMP uses linear or circular polarization. • The ESOMP operates through a geostationary satellite (or a cluster of co-located geostationary satellites) that is at least 2° away from any other geostationary satellite operating in the same frequencies and over the same coverage area. NOTE 1: ESOMPs may operate with satellites that are more closely spaced than 2° with additional operational constraints that are beyond the scope of the present document. SIST EN 303 978 V1.1.2:2013

ETSI ETSI EN 303 978 V1.1.2 (2013-02) 10 • The ESOMP is designed for unattended operation. • The ESOMP is controlled and monitored by a Network Control Facility (NCF). This function may be performed centrally (e.g. for a network of ESOMPs with a central hub) or it could be performed within the ESOMP for autonomous control. The NCF is outside the scope of the present document. The present document applies to the ESOMP 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 [i.2] (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 2: 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 [i.2] (R&TTE Directive) may apply to equipment within the scope of the present document. NOTE 3: 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.
