LC29H is a series of dual-band, multi-constellation GNSS modules that support the concurrent reception of all four global GNSS constellations: GPS, BDS, 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. By having an internal LNA and SAW filter, the module achieves better sensitivity and anti-interference capability. Featuring dual frequency support, the module delivers accuracy values of 1 m in autonomous mode and centimeter levels in the RTK capable variants. The optional function ensures the module's superior positioning performance even in weak signal areas or when GNSS signals are . 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- positioning and low power consumption makes the LC29H series perfectly suited for applications such as real time tracking and sharing economy related . Key Features: Multi-GNSS engine for GPS, GLONASS, BDS, and QZSS Reception of L1 and L5 GNSS bands signals concurrently Integrated LNA for high sensitivity Integrated SAW filter for noise cancellation Colour:Blue Material:ABS Package Contents: 2 x Quectel LC29HEA GNSS Module Only the above package content, other products are not included.
