LC29H Dual-Band, Multi-Constellation GNSS Module

Quectel's LC29H is a series of dual-band, multi-constellation GNSS modules that support the concurrent reception of all four global GNSS constellations: GPS, BDS, Galileo, and GLONASS.

Compared to GNSS modules that track only L1 signals, the LC29H series can receive and track a higher number of visible satellites in multi bands, thereby significantly mitigating the multipath effect in deep urban canyons and improving positioning accuracy. The module series achieves better sensitivity and anti-interference capability by having an internal LNA and SAW filter. The module series features dual frequency support and delivers CEP accuracy values of 1 m in autonomous mode and centimeter levels in the RTK capable variants. The optional DR function ensures the module series’ 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 positioning fix, which makes the module series an ideal solution for power-sensitive and battery-powered systems. Due to high-precision positioning and low power consumption, the LC29H series is perfectly suited for real-time tracking and sharing economy-related services.
