Quectel LC29H dual-band GNSS module

Tuesday, 28 June, 2022 | Supplied by: Quectel

Quectel Wireless Solutions has announced the LC29H — its dual-band, multi-constellation, high-precision GNSS module. Built using the Airoha AG3335 platform, the product is available in multiple variants targeting different application scenarios and optionally integrates RTK and DR.

The series offers high-performance, power-efficient solutions to meet market needs of high-precision positioning at the centimetre and decimetre levels. The modules are suitable for autonomous lawnmowers, drones, precision agriculture, micro-mobility scooters and delivery robots as well as other industrial and autonomous applications.

The product concurrently receives and processes signals from all constellations (GPS, GLONASS, BeiDou, Galileo and QZSS), which in combination with the support of SBAS maximises satellite signal availability. The module supports L1 and L5 dual-band signal reception so that terminals can speed up convergence time, improve positioning and achieve fast response times even when the signal is interrupted. The dual-band design mitigates the multipath effect experienced near high-rise buildings or in deep urban canyons, and provides good positioning performance.

Some versions contain 6-axis IMU inertial sensors (3-axis accelerometer + 3-axis gyroscope) and integrate RTK and DR positioning algorithms, allowing for continuous lane-level positioning in scenarios where the satellite signal is partially or completely blocked. When the satellite signal is reacquired, the module combines inertial sensor data with GNSS signals, and the integrated navigation can provide fast convergence times and decimetre-level positioning accuracies. In order to improve the performance when used with a passive antenna, the module has a built-in LNA and an internal SAW filter.

The product adopts a 12 nm process, dual-frequency receiver chip and advanced low-power management, thereby enabling low-power GNSS sensing and position fixing. This makes the module suitable for power-sensitive and battery-powered devices including handheld devices, asset trackers and shared vehicles. Featuring an LCC form factor and a footprint size of 12.2 x 16 x 2.5 mm, it allows for easy system integration and smooth migration of legacy designs to the latest high-precision GNSS technologies.
