Foreword This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. The present document is intended to become a Harmonized Standard, the reference of which will be published in the Official Journal of the European Communities referencing the Council Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility ("the EMC Directive") (89/336/EEC [3] as amended) and Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity ("the R&TTE Directive" [2]). The present document is part 20 of a multi-part deliverable. Full details of the entire series can be found in part 1 [1].

1 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. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

3 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the terms and definitions given in EN 301 489-1 [1], clause 3, and the following apply: carrier-on state (allocated a channel): state of an MES when it is transmitting a signal in a continuous or a non-continuous mode carrier-off state (idle mode): state of an MES when it is powered-on but not transmitting a signal, i.e. not in a carrier-on state host equipment: any equipment which has complete user functionality when not connected to the MES, and to which connection is necessary for the MES to offer additional functionality Installable Equipment (IE), Internally Mounted Equipment (IME) and Externally Mounted Equipment (EME): Installable Equipment (IE) is an equipment which is intended to be installed in a vehicle. An IE may consist of one or several modules. The IE is composed of modules intended to be externally mounted and declared by the manufacturer as Externally Mounted Equipment (EME). The remaining module(s) are defined as Internally Mounted Equipment (IME) multimode MES: equipment that accommodates radio stations of different radio systems occupied bandwidth: See ITU-R Radio Regulations [4], part A, chapter 1, Terminology RR 147. Portable Equipment (PE): is generally intended to be self-contained, free standing and portable NOTE 1: A PE would normally consist of a single module, but may consist of several interconnected modules. NOTE 2: More than one of the equipment classifications can apply to certain equipment, as described in clause 5.4, dependent upon the manufacturer's declaration of normal intended use. transmission disabled state: state of an MES when it is not authorized to transmit by the Network Control Facilities (NCF) 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: BER Bit Error Ratio CP performance criteria for Continuous Phenomena EMC ElectroMagnetic Compatibility EME Externally Mounted Equipment EUT Equipment Under Test F-MES Fixed MES IE Installable Equipment IME Internally Mounted Equipment LBRDC Low Bit Rate Data Communication LEO Low Earth Orbit MES Mobile Earth Station MSS Mobile Satellite Service NCF Network Control Facilities PE Portable Equipment PEP Peak Envelope Power P-MES Portable MES QTMA Quality of Transmission Measurement Apparatus RF Radio Frequency S-PCN Satellite Personal Communications Network STE Special Test Equipment SIST EN 301 489-20 V1.2.1:2003
