The present document specifies technical characteristic and methods of measurements for Very Small Aperture Terminal (VSAT) equipment which has the following characteristics:
• the VSAT is operating in one or more frequency ranges within 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):
- 5,850 GHz to 7,075 GHz (Earth-to-space);
- 3,400 GHz to 4,200 GHz (space-to-Earth);
- 4,500 GHz to 4,800 GHz (space-to-Earth);
• the VSAT uses linear or circular polarization;
• the VSAT operates through a geostationary satellite at least 2° 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:
- a transmit-only VSAT: designed for transmission-only of radio-communications signals in the frequency band (earth-to-space) specified in the present clause; or
- a transmit-and-receive VSAT: designed for transmission-and-reception of radio-communications signals in the frequency bands specified in the present clause; or
- a receive-only VSAT: designed for reception-only of radio-communications signals in the frequency band (space-to-Earth) specified in the present clause;
• the VSAT is designed 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 VSAT is controlled, and monitored for the transmit functionality, by a Centralized Control and Monitoring Facility (CCMF). The VSAT has to implement Control and Monitoring Functions with either Class A or Class B (structures of the radio states). The specifications associated to the CCMF facility are 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 defined for the intended use of the VSAT including all equipment as brought to the market.
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. The present document is intended to cover the provisions of Directive 2014/53/EU (Radio Equipment Directive) article 3.2.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU is given in annex A.
