1Introduction
Quectel LTE standard modules integrate a GNSS engine which supports GPS, BeiDou, Galileo and
GLONASS systems and also gpsOneXTRA Assistance technology. The high-performance GNSS engine
is suitable for various applications where the lowest-cost and accurate positioning is needed, and it
supports position tracking without any network assistance. The GNSS makes LTE standard modules
popular in application fields such as turn-by-turn navigation, asset tracking, personnel tracking,
location-aware games, as well as home and fleet management.
This document is applied to the following LTE Standard modules:
EC2x: EC21, EC25, EC20 R2.0 and EC20 R2.1
EG2x-G: EG25-G and EG21-G
EG9x: EG91 and EG95
EM05
1.1. GNSS Turning on/off Procedures
The GNSS of LTE standard modules supports location calculation without any assistance from the
network. GNSS turning on/off procedures are shown below:
Step 1: Configure GNSS parameters via AT+QGPSCFG.
Step 2: Turn on GNSS via AT+QGPS.
Step 3: After GNSS is turned on and position is fixed successfully, the positioning information can be
obtained in either of the following three ways:
1) NMEA sentences are outputted to "usbnmea" port by default. NMEA sentences can be obtained
by reading the port.
2) AT+QGPSLOC can be used to obtain positioning information directly, such as latitude, longitude,
height, GNSS positioning mode, time, number of satellites, and so on.
3) After enabling <nmeasrc> via AT+QGPSCFG="nmeasrc",1, the specified NMEA sentence can
be acquired via AT+QGPSGNMEA. If <nmeasrc> is disabled, this command cannot be used.
Step 4: Turn off GNSS via AT+QGPSEND.

1.2. NMEA Sentence Types
The NMEA sentences are compatible with NMEA-0183 protocol, and four kinds of prefixes are available
to differentiate NMEA sentences of different satellite systems, as illustrated below.
For GPS NMEA sentences, the prefix is “GP”, as below:
GPGGA- Global positioning system fix data, such as time, position, etc.
GPRMC - Recommended minimum specific GNSS data
GPGSV - GNSS satellites in view, such as number of satellites in view, satellite ID numbers, etc.
GPGSA - GNSS DOP and active satellites
GPVTG - Course over ground and ground speed
For GLONASS NMEAsentences, the prefixes are "GL" and "GN", as below:
GLGSV - GNSS satellites in view, such as number of satellites in view, satellite ID numbers, etc.
GNGSA - GNSS DOP and active satellites
GNGNS - GNSS fix data
For Galileo NMEA sentences, the prefixes are "GA", as below:
GAGGA- Global positioning system fix data, such as time, position, etc.
GARMC - Recommended minimum specific GNSS data
GAGSV - GNSS satellites in view, such as number of satellites in view, satellite ID numbers, etc.
GAGSA - GNSS DOP and active satellites
GAVTG - Course over ground and ground speed
For BeiDou NMEA sentences, the prefixes are "PQ", as below:
PQGSV - GNSS satellites in view, such as number of satellites in view, satellite ID numbers, etc.
PQGSA - GNSS DOP and active satellites
1.3. Introduction of gpsOneXTRA Assistance
gpsOneXTRA Assistance technology enhances the performance of GNSS and provides simplified GNSS
assistance delivery, including ephemeris, almanac, ionosphere, UTC, health and coarse time assistance
for GNSS engine. After activating gpsOneXTRA Assistance, the TTFF (Time to First Fix) can be reduced
by 18s~30s (or more in harsh environments with weak signals). The assistance data which is obtained
from one of the gpsOneXTRA Assistance web servers needs to be updated once a day (or every couple
of days).
Before using this function, please make sure the valid gpsOneXTRA assistance data is available first. It is
necessary to download a new gpsOneXTRA binary file which contains the data from one of the
gpsOneXTRAAssistance web servers via URLs listed below.

http://xtrapath3.izatcloud.net/xtra3grcej.bin
gpsOneXTRA assistance data needs to be updated regularly. The status of gpsOneXTRA data files can
be queried via AT+QGPSXTRADATA? before updating.
The operation procedures of gpsOneXTRAAssistance function are shown as follows:
Step 1: gpsOneXTRA Assistance function is disabled by default, and can be enabled via
AT+QGPSXTRA=1.
Step 2: Query and confirm the current validity of gpsOneXTRA data file via AT+QGPSXTRADATA?. If
the data is invalid, perform Step 3~6 then; if the data is valid, turn on GNSS engine according to
the procedures described in Chapter 1.1 directly.
Step 3: Download files with suffix “xtra2.bin”or “xtra3grc.bin”to the module via URLs listed above.
Step 4: Inject the correct gpsOneXTRAtime to GNSS engine via AT+QGPSXTRATIME.
Step 5: Inject the valid gpsOneXTRAdata file to GNSS engine via AT+QGPSXTRADATA.
Step 6: Turn on GNSS engine according to the procedures described in Chapter 1.1.
Before Step 1, it is necessary to ensure that the GNSS engine has been turned off.
For more detailed information of the AT commands mentioned above, please refer to Chapter 2.9, 2.10
and 2.11.
