1 Scope
The present document specifies technical characteristics and methods of measurements for Global Navigation Satellite
System (GNSS) User Equipment (GUE).
Global Navigation Satellite System (GNSS) User Equipment (GUE) is capable of operating as part of one or more
radionavigation-satellite service (RNSS) systems in the RNSS frequency bands given in table 1-1.
Table 1-1: Radionavigation-satellite service (RNSS) frequency bands
RNSS frequency bands Comments
1 164 MHz to 1 300 MHz space-to-Earth
1 559 MHz to 1 610 MHz space-to-Earth

A GUE receives radio signals from one or more GNSS for the purpose of radiodetermination of the position, velocity,
and/or other characteristics of an object, or the obtaining of information relating to those parameters, by means of the
propagation properties of radio waves. RNSS is defined as "A radiodetermination-satellite service used for the purpose
of radionavigation" (article 1.43 of ITU Radio Regulations [i.13]).
The present document applies to all GUE operating in the bands given in table 1-1 with the ability to receive any GNSS
(e.g. Galileo, Global Positioning System (GPS), BeiDou (BDS), Global Navigation Satellite System (GLONASS),
Space Based Augmentation Systems (SBAS)).
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.1] under the
conditions identified in annex A.

Introduction
ETSI has designed a modular structure for the standards. Each standard is a module in the structure. The modular
structure is shown in ETSI EG 203 336 [i.2].
The present document defines technical requirements to support the essential requirements of article 3.2 of the Radio
Equipment Directive [i.1] which states "Radio equipment shall be so constructed that it both effectively uses and
supports the efficient use of radio spectrum in order to avoid harmful interference".
The present document does not contain any requirement, recommendation, or information about the installation of the
GNSS user equipment.

1 Scope
The present document specifies technical characteristics and methods of measurements for Global Navigation Satellite
System (GNSS) User Equipment (GUE).
Global Navigation Satellite System (GNSS) User Equipment (GUE) is capable of operating as part of one or more
radionavigation-satellite service (RNSS) systems in the RNSS frequency bands given in table 1-1.
Table 1-1: Radionavigation-satellite service (RNSS) frequency bands
RNSS frequency bands Comments
1 164 MHz to 1 300 MHz space-to-Earth
1 559 MHz to 1 610 MHz space-to-Earth

A GUE receives radio signals from one or more GNSS for the purpose of radiodetermination of the position, velocity,
and/or other characteristics of an object, or the obtaining of information relating to those parameters, by means of the
propagation properties of radio waves. RNSS is defined as "A radiodetermination-satellite service used for the purpose
of radionavigation" (article 1.43 of ITU Radio Regulations [i.16]).
The present document applies to all GUE operating in the bands given in table 1-1 with the ability to receive any GNSS
(e.g. Galileo, Global Positioning System (GPS), BeiDou (BDS), Global Navigation Satellite System (GLONASS),
Space Based Augmentation Systems (SBAS)).
The present document applies to the GUE only. For other systems that include a GNSS receiver, the requirements of the
most appropriate harmonised standard for that type of equipment apply.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.1] under the
conditions identified in annex A.
As stated in the annex I of the Radio Equipment Directive [i.1] the present document does not cover:
• Marine equipment falling within the scope of Council Directive 96/98/EC [i.13].
• Airborne products, parts and appliances falling within the scope of Article 3 of Regulation (EC) No
216/2008 [i.14] of the European Parliament and of the Council.
NOTE: A new version of the Marine Equipment Directive has been published and the reference should be
Directive 2014/90/EU [i.15]. However, this citation has not been updated in the RED.
