Satellite Earth Stations and Systems (SES); Harmonized EN for Very Small Aperture Terminal (VSAT); Transmit-Only, Transmit/Receive or Receive-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

scope:
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,OO 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 30 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
radio-communications
- transmit and receive VSAT: designed for transmission and
reception of radio-communications
- receive only VSAT: designed for reception only of
radio-communications
- 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 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 [i] (R&TTE Directive) Article 3.2, which states that ". . . radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestriahpace 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 Directive 1999/5/EC [i] (R&TTE Directive) may apply to equipment within the scope of the present document.
