Shanghai, July 16, 2020 - Quectel Wireless Solutions, the leading global supplier of cellular and GNSS modules announced today the release of its LC29D module. The LC29D is a sub-meter level GNSS module that integrates dead reckoning (DR) and multi-band (L1/L5) real-time kinematic (RTK) algorithm technologies with fast convergence times and reliable performance. The module supports dual-band GNSS raw data output and integrates 6-axis IMU sensor to deliver high-accuracy positioning performance in seconds.

 

 

 

 

Based on the Broadcom BCM47758 GNSS chip, the LC29D can concurrently receive signals from up to six constellations (GPS, GLONASS, Galileo, IRNSS, BeiDou and QZSS) at any given time, which maximizes the availability of sub-meter level accuracy. Combining GNSS signals from dual-frequency bands (L1/L5) and RTK technology enables the LC29D to achieve high performance even in difficult conditions such as dense urban canyons. The module can also mitigate multipath effects in urban cities.

 

 

 

 

The LC29D offers a position update rate of up to 30Hz (fusion output), enabling dynamic applications like shared eMobility, delivery robots and precision agriculture to receive position information with lower latency. By enabling easy integration of advanced RTK multi-band algorithms, the module helps developers quickly bring their devices to market.

 

Embedded with 6-axis MEMS sensor, devices powered by the LC29D can quickly report motion, which enables consistent high-precision positioning capabilities when combined with the dead reckoning (DR) algorithm, even in weak-signal environments such as tunnels and underground parking structures.

 

The high-precision module offers better performance than products in the market in positioning precision, sensitivity, time to first fix (TTFF), update rates and latency. In addition, the LC29D also integrates a surface acoustic wave (SAW) filter which filters out the undesirable interfering frequencies, and a low noise amplifier (LNA) in the RF path that can increase the signal strength of weak radio signals in order to improve the receiver system's sensitivity.

 

 

 

 

Designed in the international standard dimension of 16.0mm × 12.2mm ×2.4mm, the LC29D uses the 28nm process and an integrated low power consumption algorithm, which significantly extends the battery life and makes the LC29D ideal for power-sensitive devices such as small eMobility vehicles, e-Scooters and e-Skateboards, as well as trackers.

 

“With positioning technologies moving on, requirements for higher precision, lower cost and lower consumption grow rapidly. We are very happy to launch this new-gen sub-meter level positioning module based on the Broadcom BCM47758 GNSS chip, which demonstrates Quectel's leading position in bringing cutting-edge high precision positioning modules to the market,” said Jeffrey Song, Product Director at Quectel. “Quectel and Broadcom have long been cooperating to offer high-performance positioning solutions for consumer and industrial customers, which will help futureproof their IoT deployments and create a connected world.”

 

“We are thrilled to have enabled Quectel with our leading-edge BCM47758 dual-frequency GNSS receiver chip,” said Hunter Kong, product marketing director for the Wireless Communications and Connectivity Division at Broadcom. “Equipped with Broadcom's dual-frequency GNSS innovation, Quectel's LC29D is uniquely positioned to address very high precision LBS requirements for both industrial and consumer markets."
