company blog about Quectel GNSS Positioning Module LC29HDAEK High Accuracy, Dual Frequency GNSS Module

Today, QUECTEL's new dual-band, multi-constellation, high-precision GNSS positioning module LC29H is officially launched. The module uses dual-frequency positioning technology, combined with RTK (Real-time Dynamic Carrier Phase Difference) technology and DR (Inertial Navigation Technology), to meet the demand for centimetre- and decimetre-level high-precision positioning, and help lawnmowers, drones, intelligent agricultural machines, shared two-wheelers and other industry applications to achieve an upgraded experience.

Shenzhen Mingjiada Electronics Co., Ltd. provides QUECTEL's new GNSS positioning module, LC29HDAEK, a high-precision, dual-frequency GNSS module that supports simultaneous reception of all four of the world's GNSS satellites: GPS, BDS, Galileo and GLONASS.

Product Overview

The QUECTEL LC29H is a dual-band, multi-constellation, high-precision positioning module with inertial navigation and RTK fusion.

Compared to GNSS modules that only track L1 signals, the LC29H series can receive and track visible satellites in a wider range of frequency bands, which greatly mitigates multipath effects in deep urban canyons and improves positioning accuracy. With a built-in low-noise amplifier and surface acoustic wave filter, the module achieves higher sensitivity and anti-interference capability. The module supports dual-frequency and provides CEP accuracy values of 1 metre in autonomous mode and centimetre-level CEP accuracy values in RTK-enabled variants. An optional DR function ensures that the module delivers excellent positioning performance even in areas with weak signals or when GNSS signals are not available.

Based on a receiver chip using 12nm technology, the LC29H series offers advanced power management features for low-power GNSS sensing and position fixing, making the module an ideal solution for power-sensitive and battery-powered systems.The LC29H series features high-precision positioning and low-power consumption, making it ideally suited for applications such as real-time tracking and services related to the sharing economy.

The company recycles QUECTEL positioning module LC29HDAEK high-precision GNSS module, and only recycles regular channel sources, such as agents, traders, terminal factories, etc., and does not accept sources that are not regular channels.
