ETSI - EN 301 428
Satellite Earth Stations and Systems (SES); Harmonized EN for Very Small Aperture Terminal (VSAT); Transmit-Only, Transmit/Receive or Recieve-Only Satellite Earth Stations Operating in the 11/12/14 GHz Frequency Bands Covering Essential Requirements under Article 3.2 of the R&TTE Directive
|Publication Date:||1 May 2000|
The present document applies to Very Small Aperture Terminals (VSATs) which have the following characteristics:
- the VSAT are operating in one or more frequency ranges in the part of the following bands allocated exclusively to the Fixed Satellite Services (FSS):
- 14,00 GHz to 14,25 GHz (earth-to-space);
- 12,50 GHz to 12,75 GHz (space-to-earth);
or in the shared parts of the following bands, allocated to the FSS and Fixed Services (FS):
- 14,25 GHz to 14,50 GHz (earth-to-space);
- 10,70 GHz to 11,70 GHz (space-to-earth).
- the VSAT use linear polarization.
- the VSAT operate 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 3,8 m, or equivalent corresponding aperture.
- the VSAT are either:
- transmit only VSAT: designed for transmission only of
- transmit and receive VSAT: designed for transmission and
reception of radio-communications
- receive only VSAT: designed for reception only of
- the VSAT are designed usually for unattended operation.
- the VSAT are 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 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.
The present document is intended to cover the provisions of Directive 1999/5/EC  (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 specifies technical requirements in respect of essential requirements under other parts of Article 3 of the R&TTE Directive  may apply to equipment within the scope of the present document.
NOTE: A list of such ENs is included on the ETSI web site.
