Electromagnetic compatibility and Radio spectrum Matters (ERM); ElectroMagnetic Compatibility (EMC) standard for radio equipment and services; Part 20: Specific conditions for Mobile Earth Stations (MES) used in the Mobile Satellite Services (MSS)

Scope

The present document, together with EN 301 489-1 [1], covers the assessment of Mobile Earth Stations (MES) as
defined in annex A used within Satellite radio services, and ancillary equipment in respect of ElectroMagnetic
Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of the equipment are not
included in the present document. Such technical specifications are found in the relevant product standards for the
effective use of the radio spectrum.
The present document specifies the applicable test conditions, performance assessment and performance criteria for
MESs and for the associated ancillary equipment.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and EN 301 489-1 [1], the provisions of the present document take precedence.
The environmental classification and the emission and immunity requirements used in the present document are as
stated in EN 301 489-1 [1], except for any special conditions included in the present document. The applicable
environment(s) referred to in EN 301 489-1 [1] where the MES may be used, shall be declared by the manufacturer.
For a multimode radio station, the present document only applies to the radio station when operated in the Mobile
Satellite Service mode.
