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)).

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)).

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)).
