Introduction
Quectel EP06&EG06&EM06 modules integrate a GNSS engine which supports GPS, BeiDou, Galileo
and GLONASS systems, and also it supports gpsOneXTRA Assistance technology. The high
performance GNSS engine is suitable for various applications where lowest-cost and accurate positioning
is needed, and it supports position tracking without network assistance. EP06&EG06&EM06 GNSS can
be applied in the following applications: turn-by-turn navigation, asset tracking, personnel tracking,
location-aware games, as well as home and fleet management.
1.1. GNSS Turning on/off Procedures
The GNSS of EP06&EG06&EM06 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 three ways:
1) NMEA sentences are outputted to "usbnmea" port by default. Customers can read the port to
obtain NMEA sentences.
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
, customers can acquire the
specified NMEA sentence via
AT+QGPSGNMEA
. If
<nmeasrc>
is disabled, this command
cannot be used.
Step 4:
GNSS can be turned off in two ways:
1)
If the parameter
<fixcount>
of
AT+QGPS
is
set to 0 in
Step 2
, GNSS will get position
continuously
, and it can be turned off via
A
T+QGPSEND
.
2) If
<fixcount>
reaches the specified value, then GNSS will stop automatically.
