  • GNSS RB31E series

    GNSS RB31E series

    The RB31E is an AEC-Q100 qualified dual-band GNSS module, with integrated multi-band RTK technology for centimeter-level accuracy. The module features the STMicroelectronics® 5th generation positioning receiver platform with 80 tracking channels and 4 fast acquisition channels, compatible with up to 4 constellations (GPS, GLONASS, Galileo and BDS) as well as QZSS.

    The RB31E provides dead reckoning capabilities with an integrated inertial measurement unit (IMU) to provide continual, highly precise positioning. The integrated state-of-the-art  algorithms fuse the IMU data, GNSS measurements, wheel tick sensor input and vehicle dynamics, to provide lane-accurate positioning where GNSS alone would fail. The module supports standard RTCM corrections from 3rd party base stations or correction networks to achieve centimeter-level positioning in seconds, allowing it to perform excellently under challenging conditions such as urban canyons.

    The RB31E is designed for easy integration with minimal e-BOM and is well-suited for mass market adoption. Due to its compact design, light weight, and low power consumption, it is ideal for vehicle markets such as automotive navigation, ADAS and V2X, as well as applications in precision smart agriculture.

  • GNSS LC29H series

    GNSS LC29H series

    C29H is a series of dual-band, multi-constellation GNSS modules that support the concurrent reception of all four global GNSS constellations: GPS, BDS, Galileo and GLONASS.

    Compared to GNSS modules that track only L1 signals, the LC29H series can receive and track a higher number of visible satellites in multi bands, thereby significantly mitigating the multipath effect in deep urban canyons and improving positioning accuracy. By having an internal LNA and SAW filter, the module achieves better sensitivity and anti-interference capability. Featuring dual frequency support, the module delivers CEP accuracy values of 1 m in autonomous mode and centimeter levels in the RTK capable variants. The optional DR function ensures the module’s superior positioning performance even in weak signal areas or when GNSS signals are not available.

    Based on the receiver chip using 12 nm technology, the LC29H series provides advanced power management enabling low-power GNSS sensing and position fix, which makes the module an ideal solution for power-sensitive and battery-powered systems. Featuring high-precision positioning and low power consumption makes the LC29H series perfectly suited for applications such as real time tracking and sharing economy related services.
