EVS-EN 303 699 V1.2.1:2026

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
Frequency Bands/frequencies
Transmit (Earth-to-space) 1; 27,5 GHz to 29,1 GHz
Transmit (Earth-to-space) 2; 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 21,2GHz (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 is given in annex A.
