Introduction

Quectel BG96 module integrates a GNSS engine which supports GPS, BeiDou, Galileo, GLONASS and
QZSS 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. BG96 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

BG96 GNSS 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, you can obtain the positioning
information in three ways:
1) NMEA sentences are output to "usbnmea" port by default. Read the port to obtain NMEA
sentences.
2) Use AT+QGPSLOC to obtain positioning information, such as latitude, longitude, height, GNSS
positioning mode, time and number of satellites.
3) After enabling <NMEA_src> via AT+QGPSCFG="nmeasrc",1, you can acquire the specified
NMEA sentence via AT+QGPSGNMEA. If <NMEA_src> is disabled, the command
AT+QGPSGNMEA cannot be used.
Step 4: GNSS can be turned off in two ways:
1) If <fix_count> of AT+QGPS
turned off via AT+QGPSEND.
2) If <fix_count> reaches the specified value, the GNSS is stopped automatically.
