Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Satellite Earth Stations and Systems (SES).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC (as amended) laying down a procedure for the provision of information in the field of
technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive") [1].
Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A.

The left hand edge of the figure shows the different clauses of article 3 of the Directive [1].
For article 3.3 various horizontal boxes are shown. Their dotted lines indicate that no essential requirements in these
areas have yet been adopted by the Commission. If such essential requirements are adopted, they will be elaborated in
individual standards whose scope is likely to be specified by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum. The scopes of these standards
are specified either by frequency (normally in the case where frequency bands are harmonized) or by radio equipment
type.
For article 3.1(b), the diagram shows the new single multipart product EMC standard for radio, and the existing
collection of generic and base standards currently used under the EMC Directive [2]. The parts of this new standard will
become available in the second half of 2000, and the existing separate EMC standards will be used until it is available.
For article 3.1(a) the diagram shows the existing safety standards currently used under the LV Directive and the
possibility of a new standard on health relating to radio emissions
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both.
The modular approach has been taken because:
- it minimizes the number of standards needed. Because equipment may have multiple interfaces and functions it
is not practicable to produce a single standard for each possible combination of functions that may occur in an
equipment;
- it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions;
without requiring alteration of standards that are already published.
The present document is based on EN 301 443 [4] and, for class B Control and Monitoring Functions on
EN 301 459 [5]. It allows the choice of either a class A Control and Monitoring system or a class B Control and
Monitoring system. The class B system is more suitable for networks comprising very many terminals.
The determination of the parameters of the user earth stations using a given geo-stationary 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. For this reason the requirement on the cross polarization discrimination which was in
TBR 043 [6] has not been copied in the present document and inter-modulation limits inside the band 5,850 GHz to
6,650 GHz are to be determined by system design and are subject to satellite operator specifications.
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
VSAT.
All parts of the indoor unit related to reception, processing and presentation of the received information except the
control channel are not within the scope of the present document. The syntax of the control channel messages is outside
the scope of the present document.

1 Scope
The present document applies to Very Small Aperture Terminals (VSATs) which have the following characteristics:
- the VSATs are operating in the following bands allocated to the Fixed Satellite Service (FSS), shared with other
services, e.g. the Fixed Service (FS) and the Mobile Service (MS):
- 5,85 GHz to 6,65 GHz (earth-to-space);
- 3,40 GHz to 4,20 GHz (space-to-earth);
- the VSAT uses linear or circular polarization;
- the VSAT operates through a geostationary satellite at least 3° away from any other geostationary satellite
operatingin the same frequencybandand coveringthesamearea;
- the VSAT antenna diameter does not exceed 7,3 m, or equivalent effective area;
- the VSAT is either:
- transmit-only VSAT: designed for transmission-only of radio-communications signals in the frequency band
(earth-to-space) specified above; or
- transmit-and-receive VSAT: designed for transmission-and-reception of radio-communications signals in the
frequency bands specified above; or
- receive-only VSAT: designed for reception-only of radio-communications signals in the frequency band
(space-to-earth) specified above;
- the VSAT is designed usually for unattended operation;
- the VSAT 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 between users;
- the transmit-only and transmit-and-receive VSAT are controlled and monitored by a Centralized Control and
Monitoring Function (CCMF). The CCMF is outside the scope of the present document.
The present document applies to the VSAT with its ancillary equipment and its various terrestrial ports, and when
operated within the boundary limits of the operational environmental profile declared by the applicant and when
installed as required by the applicant by 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".
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 R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org/.
