GPS-RTK Base Station LC29H(BS) Dual-band L1+L2 for Raspberry Pi

With the GPS/RTK dual-band module LC29H(BS) for Raspberry Pi, you receive a high-precision GNSS module that enables centimeter-accurate positioning. Thanks to the support of L1 and L5 frequencies, you can significantly enhance positioning accuracy and reduce multipath effects in urban canyons. This module is ideal for real-time tracking systems and applications in the sharing economy. It can receive multiple GNSS systems simultaneously while remaining power-efficient. Built-in amplifiers and filters ensure high sensitivity and strong interference resistance. With RTK technology, you can set up a base station to transmit correction data and further increase positioning accuracy.

Info: If you use the Raspberry Pi 5, please change the UART serial port ttyS0 to the corresponding ttyAMA0. More information on the Waveshare Wiki.
