                  Quectel LC29DCMD Dual-Band with RTK/DRMulti-Constellation GNSS Module

Featuring concurrent multi-constellation GNSS receiver for dual GNSS bands, an integrated 6-axis MEMS sensor, as well as the sophisticated RTK and dead-reckoning algorithms that fuse the sensor data, GNSS measurement, and wheel ticks, the LC29DCMD module can provide sub-meter level positioning accuracy under open-sky environment.

Compared with GNSS modules working on the L1 band only, the LC29DCMD module can track both L1 and L5 bands for GPS, Galileo, QZSS and BeiDou satellites, L1 band for GLONASS satellite, as well as L5 band for IRNSS satellite. This greatly increases the number of satellites involved in tracking and positioning, thereby improving positioning accuracy and significantly reducing the multipath effect caused by tall buildings in urban environments.

Its built-in LNAs and SAW filters ensure better positioning in weak signal areas and other challenging environments.

Due to its high precision, the LC29DCMD module is an excellent choice for real-time tracking systems, such as vehicle, personnel and asset tracking, or sharing economy applications.
