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 constellation 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" (No. 1.43 of the 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
constellation (e.g. BeiDou (BDS), Galileo, Global Navigation Satellite System (GLONASS), Global Positioning System
(GPS), Space Based Augmentation System (SBAS)).
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.

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 constellation 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" (No. 1.43 of the 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
constellation (e.g. BeiDou (BDS), Galileo, Global Navigation Satellite System (GLONASS), Global Positioning System
(GPS), Space Based Augmentation System (SBAS)).

Executive summary
The present document gives the technical requirements (clause 4) and test methodology (clause 5) for presumption of
conformity of GNSS User Equipment with article 3.2 of the Radio Equipment Directive (2014/53/EU) [i.1].
Introduction
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 constellation 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" (No. 1.43 of the 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
constellation (e.g. BeiDou (BDS), Galileo, Global Navigation Satellite System (GLONASS), Global Positioning System
(GPS), Space Based Augmentation System (SBAS)).
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.
