SSH EN 301 443 V1.2.1:2001

Satellite Earth Stations and Systems (SES); Harmonized EN for Very Small Aperture Terminal (VSAT); Transmit-only, transmit-and-receive, receive-only satellite earth stations operating in the 4 GHz and 6 GHz frequency bands covering essential requirements under article 3.2 of the R&TTE Directive

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
operating in the same frequency band and covering the same area;
- 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.
