WAVE-25279 (DA) GPS/RTK HAT Series Dual-band GPS Module for Raspberry Pi, Dual-band L1+L5 Positioning Technology

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.

General features of the LC29H series include:

• 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.

LC29H(DA) GPS/RTK HAT version supports the following features:

• Supports fast convergence dual-band RTK centimeter-level positioning, suitable for high-precision positioning of terminal devices.
