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 ESOMP comprises of one or more emitters and the system overview given in figure 1 should be
interpreted accordingly.
• The transmit and receive frequencies are shown in table 1.
Table 1: Frequency bands
Frequency Bands/frequencies
Transmit (Earth-to-space) 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz
Receive (space-to-Earth) 17,30 GHz to 20,20 GHz

• The ESOMP transmits within the frequency range from 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz,
which is a band allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. National
regulations will specify the bands available for the operation of the ESOMP. Such regulations may designate
some parts of the frequency range 27,5 GHz to 29,1 GHz to terrestrial services such as the Fixed Service.
However, the operation of the ESOMP may be permitted under national regulations in the 29,50 GHz to
30,00 GHz band since this band is allocated on a primary basis to the Fixed-Satellite Service.
• 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 non-geostationary satellites.
• The ESOMP is designed for unattended operation.
ETSI
10 ETSI EN 303 979 V1.1.1 (2015-07)
• 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 ESOMP operating in the 27,5 GHz to 28,6 GHz and 29,5 GHz to 30 GHz bands: epfd limits given in
Article 22 of the ITU Radio Regulations [i.6] apply for the ESOMPs operating with the NGSO system for the
protection of the GSO networks (see No 22.5D of the ITU RR).
• ESOMP operating in the 28,6 GHz to 29,1 GHz band: No 9.11A of the ITU RR applies to the NGSO network
of the ESOMP, meaning that the NGSO will be required to coordinate with earlier filed GSO networks or
NGSO systems (See No. 5.523A of the ITU RR).
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 1: 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 2: A list of such ENs is included on the web site http://www.newapproach.org/.

ETSI ETSI EN 303 979 V1.1.1 (2015-07) 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 ESOMP comprises of one or more emitters and the system overview given in figure 1 should be interpreted accordingly. • The transmit and receive frequencies are shown in table 1. Table 1: Frequency bands
Frequency Bands/frequencies
Transmit (Earth-to-space) 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz Receive (space-to-Earth) 17,30 GHz to 20,20 GHz
• The ESOMP transmits within the frequency range from 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz, which is a band allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. National regulations will specify the bands available for the operation of the ESOMP. Such regulations may designate some parts of the frequency range 27,5 GHz to 29,1 GHz to terrestrial services such as the Fixed Service. However, the operation of the ESOMP may be permitted under national regulations in the 29,50 GHz to 30,00 GHz band since this band is allocated on a primary basis to the Fixed-Satellite Service. • 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 non-geostationary satellites. • The ESOMP is designed for unattended operation. SIST EN 303 979 V1.1.1:2015

ETSI ETSI EN 303 979 V1.1.1 (2015-07) 10 • 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 ESOMP operating in the 27,5 GHz to 28,6 GHz and 29,5 GHz to 30 GHz bands: epfd limits given in Article 22 of the ITU Radio Regulations [i.6] apply for the ESOMPs operating with the NGSO system for the protection of the GSO networks (see No 22.5D of the ITU RR). • ESOMP operating in the 28,6 GHz to 29,1 GHz band: No 9.11A of the ITU RR applies to the NGSO network of the ESOMP, meaning that the NGSO will be required to coordinate with earlier filed GSO networks or NGSO systems (See No. 5.523A of the ITU RR). 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 1: 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 2: 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.
