Quectel and Broadcom cooperate to launch superior performance dual-band sub-meter level GNSS positioning module for eMobility




SHANGHAI, July 16, 2020 /PRNewswire=KYODO JBN/ --


Quectel Wireless Solutions (https://www.quectel.com/ ), the leading global

supplier of cellular and GNSS modules announced today the release of its LC29D

module (https://www.quectel.com/product/lc29d.htm ). 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.


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. 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 DR algorithm, even in weak-signal

environments such as tunnels and underground parking structures.
