Quectel L26-P Compact GNSS Module - SATRON electronics
Quectel L26-P
Compact GNSS Module

The L26-P is a single band, multi-constellation GNSS raw data receiver for high precision positioning applications. The
module has an integrated 6-axis sensor (IMU), and it can output GNSS raw data concurrently with the sensor raw
data. The firmware also supports an option to enable the output of standard NMEA messages. The module can
acquire and track GPS, GLONASS, BDS, Galileo and QZSS signals and the built-in LNA ensures better performance in
challenging signal conditions scenarios. Compared with GPS only receivers, enabling multiple GNSS systems increases
the number of visible satellites, and it will lead into enhanced performance. The ability to use the GNSS raw data in
collaboration with the IMU data on an external position engine (customer MCU side) makes this module very
attractive for many applications.
Its superb performance makes L26-P ideal for base stations, automotive, industrial and consumer applications
