Draft Scope:

The present document specifies technical characteristics and methods of measurements for Very Small Aperture 
Terminals (VSATs) intended to 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 and which have the following characteristics: 
• The VSAT operates in the following bands, or parts thereof, allocated to the Fixed Satellite Service (FSS): - - - - 
10,70 GHz to 11,70 GHz (space-to-Earth); 
12,50 GHz to 12,75 GHz (space-to-Earth); 
14,00 GHz to 14,25 GHz (Earth-to-space); 
14,25 GHz to 14,50 GHz (Earth-to-space); 
• The VSAT uses linear polarization. 
• The VSAT antenna diameter does not exceed 3,8 m, or equivalent effective area. 
• The VSAT is either: - - - 
a transmit only VSAT: designed for transmission only of radio-communications signals in any of the 
frequency bands (earth-to-space) specified above; or 
a transmit and receive VSAT: designed for transmission and reception of radio-communications signals 
in any of the frequency bands specified above; or 
a receive only VSAT: designed for reception only of radio-communications signals in any of the 
frequency bands (space-earth) specified above. 
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 
of the MES.
