GNSS Module Series
1 Introduction
Quectel LC26G&LC76G&LC86G GNSS modules support GPS, GLONASS, Galileo, BDS and QZSS
constellations. Concurrent tracking of GPS L1 C/A, GLONASS L1, BDS B1I, Galileo E1 and QZSS L1 C/A
frequency bands provides fast and accurate acquisition and makes these modules ideal solutions for
positioning and navigation in various vertical markets.
This document describes the software commands that are needed to control and modify the module
configuration. The software commands are NMEA proprietary commands defined by the chipset supplier
(PAIR messages). To report GNSS information, the modules supports output messages in NMEA 0183
standard protocol format.
NOTE
Only use the commands listed in this document. Quectel assumes no responsibility if other commands
are used.
