LC29H Series Dual-band GPS Module for Raspberry Pi, Dual-band L1+L5 Positioning Technology, Optional RTK Function

The Waveshare LC29H Series Dual-Band GPS Module (SKU:25280) is an advanced GNSS positioning solution built for Raspberry Pi and similar SBC platforms. It uses the LC29H GNSS chipset with dual-band L1+L5 signal tracking, allowing the module to receive multiple satellite signals simultaneously from GPS, GLONASS, BeiDou, Galileo, and QZSS constellations — significantly improving positional accuracy and reducing multipath errors, especially in urban areas and signal-challenged environments.

This module has an optional RTK (Real-Time Kinematic) function, which can deliver centimeter-level positioning accuracy when used with appropriate correction data and reference stations. It also supports GNSS raw observation and correction data output, making it suitable for high-precision mapping, surveying, navigation, and autonomous systems.
