The present document covers requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference. The present document applies to 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; 27,5 GHz to 29,1 GHz
Transmit (Earth-to-space) 2; 29,5 GHz to 30,0 GHz
Receive (space-to-Earth); 17,30 GHz to 20,20 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 is a band allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. National regulations will specify the bands available for the operation of the ES. Such regulations may designate some parts of the frequency range 27,5 GHz to 29,1 GHz to terrestrial services such as the Fixed Service. However, the operation of the ES may be permitted under national regulations in the 29,50 GHz to 30,00 GHz band since this band is allocated on a primary basis to the Fixed Satellite Service.
• The ES receives in one or more frequencies 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.
• 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 operating in the 27,5 GHz to 28,6 GHz and 29,5 GHz to 30 GHz bands: epfd limits given in article 22 of the ITU Radio Regulations apply for the ESs operating with the NGSO system for the protection of the GSO networks (see No. 22.5D of the ITU RR).
• ES operating in the 28,6 GHz to 29,1 GHz band: No. 9.11A of the ITU RR [i.5] applies to the NGSO network of the ES, meaning that the NGSO will be required to coordinate with earlier filed GSO networks or NGSO systems (See No. 5.523A of the ITU RR [i.5]).
• The ES has one or more directive antennas that track satellites.
The present document applies to the ES with its ancillary equipment and its various telecommunication ports, and when operated within the boundary limits of the operational environmental profile as declared by the manufacturer and when installed as required by the manufacturer's declaration or in the user documentation.
NOTE 1: Operational requirements are defined by national administrations and by relevant ECC Decisions. 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 2014/53/EU may apply to equipment within the scope of the present document.
NOTE 2: A list of such ENs is included on the web site http://www.newapproach.org.
NOTE 3: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU is given in annex A.
