Draft Details

The present document specifies technical characteristics and methods for measurements for satellite communications 
Earth Stations (ES) with the following characteristics: 
• The ES is designed for stationary operation. 
• The ES 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. 
• The transmit and receive frequencies are shown in Table 1. 
Table 1: Frequency bands 
Transmit (Earth-to-space) 1 
Frequency Bands/frequencies 
Transmit (Earth-to-space) 2 
27,5 GHz to 29,1 GHz  
29,5 GHz to 30,0 GHz 
Receive (space-to-Earth) 
17,3 GHz to 20,2 GHz 
• The ES transmits within the frequency range from 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz, which 
are bands allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. 
• At the national level, terminals covered by the present document, might operate on a co-frequency basis, with 
stations of other FSS networks / systems or with stations of other services. The present document does not 
cover requirements for ensuring protection of such services. 
• The ES receives within the range from 17,30 GHz to 20,20 GHz (FSS). 
• The ES uses linear or circular polarization. 
• The ES operates through non-geostationary satellites. 
• The ES is designed for unattended operation and it does not address specifications or requirements for earth 
stations operating as gateways or master earth station. 
• The ES is controlled and monitored by a Network Control Facility (NCF). This function may be performed 
centrally (e.g. for a network of ESs with a central hub) or it could be performed within the ES for autonomous 
control. The NCF is outside the scope of the present document. 
• The ES has one or more directive antennas that track satellites. 
The present document may also be applicable to the frequency bands 30,0 GHz to 31,0 GHz (Earth-to-space) and 
20,2 GHz to 21,2 GHz (space-to-Earth) subject to national regulation. 
The present document applies to the ES including its ancillary equipment and its various telecommunication ports, and 
when operated within the boundary limits of the operational environmental profile as defined by the intended use of the 
ES 
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive 
2014/53/EU [i.1] is given in annex A.
