Quectel LC29H Series
Dual-Band Multi-Constellation GNSS Module with RTK and DR Functions
LC29H is a series of dual-band, multi-constellation GNSS modules that support the concurrent reception of global GNSS constellations such as GPS, BDS, Galileo and GLONASS.
Compared to GNSS modules that track only L1 signals, the LC29H series can track a higher number of visible satellites in multi bands, thereby significantly mitigating the multipath effect in deep urban canyons and improving positioning accuracy. By having an internal LNA and SAW filter, the module achieves improved sensitivity and antiinterference capability. Featuring dual frequency support, the module delivers enhanced accuracy values of 1 m in autonomous mode and centimeter levels in the RTK capable variants. The optional DR function ensures the module’s superior positioning performance even in weak signal areas or when GNSS signals are not available.
Based on the receiver chip using 12 nm technology, the LC29H series 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 series perfectly suited for applications such as real time tracking and sharing economy related services.
