Quectel LC29D
Ultra-Small Dual-Band
Multi-Constellation GNSS Module
Featuring concurrent mul-constellaon GNSS receiver for dual GNSS bands, an integrated 6-axis MEMS sensor, as well as
the sophiscated RTK and dead-reckoning algorithms that fuse the sensor data, GNSS measurement, and wheel cks, the
LC29D module can provide sub-meter level posioning accuracy under open-sky environment.
Compared with GNSS modules working on the L1 band only, the LC29D module can track both L1 and L5 bands for GPS,
Galileo and QZSS satellites, L1 band for GLONASS and BeiDou satellites, as well as L5 band for IRNSS satellite. This greatly
increases the number of satellites involved in tracking and posioning, thereby improving posioning accuracy and
signicantly reducing the mulpath eect caused by tall buildings in urban environments.
Its built-in LNAs and SAW lters ensure beer posioning in weak signal areas and other challenging environments.
Due to its high precision, the LC29D module is an excellent choice for real-me tracking systems, such as vehicle, personnel
and asset tracking, or sharing economy applicaons.
