Quectel Wireless Solutions, a leading global supplier of cellular and GNSS modules announced the release of 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 LC29D module supports dual-band GNSS raw data output and integrates a 6-axis IMU sensor to deliver high-accuracy positioning information 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.
Key Features of LC29D module:
- The LC29D offers a position update rate of up to 30 Hz (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 a 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 16.0 × 12.2 ×2.4 mm, the LC29D uses the 28 nm 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.
Quectel and Broadcom have been working together for some time now to offer high-performance positioning solutions for consumer and industrial customers, which will help futureproof their IoT deployments and create a connected world.
