Quectel LC29H Dual-Band Multi-Constellation GNSS Module

Quectel LC29H is a dual-band, multi-constellation GNSS module based on MTK platform. It can concurrently track GPS, BeiDou, Galileo and QZSS satellite signals on L1 and L5 bands, as well as GLONASS satellite signal on L1 band. Compared with GNSS modules that can track only L1 signals, LC29H can track more visible satellites, and thereby significantly mitigates the multipath effect in urban canyons, reduces signal acquisition time, and improves positioning accuracy.

Quectel LC29H module's integrated LNAs enable high sensitivity and high precision positioning, and the integrated SAW filters improve its anti-interference capability, while the dead reckoning function ensures reliable positioning performance even in signal-challenged environments. LC29H supports advanced power management that enables low-power GNSS sensing and position fix, which makes the module ideal for power-sensitive applications and battery-powered systems. Its low power consumption and high precision makes LC29H ideal for solutions such as real-time tracking systems, sharing economy applications and more.
