The LC29H series can track L1+L5 dual-frequency and multi-GNSS signals, reducing multipath effects in urban canyons and improving positioning accuracy while maintaining low power consumption. With built-in LNA and SAW filter to achieve high sensitivity and strong anti-interference capability. Adopts dual-band positioning and RTK technology to meet the need of centimeter-level high-precision positioning. Ideal for real-time tracking systems and sharing economy applications, helping to develop applications such as drones, smart farm machinery, shared two-wheelers, etc.

  • Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
  • Supports simultaneous tracking of L1+L5 dual-band satellite signals, reducing multipath effects in urban canyons and improving positioning accuracy
  • Supports concurrent receiving of multi-GNSS systems (GPS, BDS, GLONASS, Galileo and QZSS) while maintaining low power consumption
  • Built-in low noise amplifier and acoustic surface filter to realize -165dBm high sensitivity and enhance anti-interference performance
  • Supports multi-frequency active interference cancellation, effectively suppressing or eliminating narrowband signal (WiFi/2/3/4/5G) interference to ensure navigation accuracy
  • A-GNSS (Assisted GNSS) support, reducing the time to first fix (TTFF) with cold start when powered on to 5 seconds
  • Support QGNSS software, easy to set various module functions
  • Onboard battery holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts
  • Onboard 4 LED indicators for module operating status
  • Comes with online development resources and manual (Python examples for Raspberry Pi/Jetson Nano)




RTK Mobile Station, RTK base station, Centimeter positioning

The LC29H(BS) module is used as an RTK Base Station, while the LC29H(DA) module is used as an RTK Mobile Station. By setting up continuous running reference stations on the ground known fixed coordinates using the LC29H (BS) module, or by paid RTK base station enhanced services, transmitting GNSS calibration value to LC29H (DA) terminals which uploading rough positioning data, the terminals, with errors like multipath refraction, is able to calculate error value in real time, for centimeter-level positioning in seconds.
