Quectel LC29H
Dual-Band Multi-Constellation
GNSS Module with RTK and DR
Functions
LC29H is a dual-band, multi-constellation GNSS module that supports the concurrent reception of five GNSS
constellations: GPS, BDS, Galileo, QZSS and GLONASS.
Compared to GNSS modules that track only L1 signals, the LC29H series can receive and track a higher number of
visible satellites, thereby significantly mitigating the multipath effect in deep urban canyons, reducing signal
acquisition times and improving positioning accuracy. By having an internal LNA and SAW filter, the module achieves
better sensitivity and anti-interference capability. The optional DR* function ensures its superior positioning
performance even in weak signal areas or when GNSS signals are not available.
LC29H provides advanced power management enabling low-power GNSS sensing and position fix, which makes the
module an ideal solution for power-sensitive and battery-powered systems.
Featuring high-precision positioning and low power consumption makes the LC29H perfectly suitable for applications
such as real time tracking and sharing economy related devices.
