    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.

    Quectel Wireless Solutions has published a new white paper titled “Why GNSS for eMobility must balance precision, price, power and packaging.”

    According to Quectel, this paper details the challenges eMobility providers face in enabling vehicles such as eScooters and eBikes to be located in deep urban canyons. The white paper also examines why accurate location data will be vital in enabling the ride-sharing industry to comply with regulation to restrict eMobility usage on sidewalks and other areas, Quectel said.

    The report also details drive test data conducted on an eScooter in San Francisco. The data demonstrates the enhanced accuracy offered by L1 and L5 plus dead reckoning capability.

    Finally, the white paper discusses how the Quectel LC79D is enabling the eMobility industry to harness the fusion of different sensors in a very small footprint at low incremental cost with unparalleled accuracy, the company added.

    “eMobility providers face substantial challenges when dealing with location in deep urban environments,” said Mark Murray, vice president of sales for GNSS and automotive at Quectel. “First and foremost, customers need to be able to find the vehicle and cities need to have the assurances that these eBikes and eScooters are operated in mutually agreed locations.”
