Waveshare For Raspberry Pi LC29H Series Dual-Band L1+L5 Positioning GPS Module, Spec: (DA) GPS/RTK HAT

Features:
1. 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.
2. Built-in LNA and SAW filters to achieve high sensitivity and strong anti-interference ability.
3. Use dual-frequency positioning and RTK technology to meet centimeter-level high-precision positioning requirements.
4. Suitable for real-time tracking systems and sharing economy applications, helping to develop applications such as drones, smart agricultural machinery, and shared two-wheelers.
5. Standard Raspberry Pi 40PIN GPIO expansion header, supports Raspberry Pi series boards and Jetson Nano
6. Supports simultaneous tracking of L1+L5 dual-frequency satellite signals, reducing the multipath effect in urban canyons and improving positioning accuracy.
7. Supports concurrent reception of multiple GNSS systems (GPS, BDS, GLONASS, Galileo and QZSS) while maintaining low power consumption
8. Built-in low-noise amplifier and acoustic surface filter to achieve -165dBm high sensitivity and enhanced anti-interference performance
9. Supports multi-frequency active interference cancellation, effectively suppressing or eliminating narrowband signal (WiFi/2/3/4/5G) interference to ensure navigation accuracy
10. A-GNSS (Assisted GNSS) support, reducing the cold start time to first fix (TTFF) at power-on to 5 seconds
11. Support QGNSS software to facilitate setting various module functions
12. Onboard battery holder, supports ML1220 rechargeable battery, used to save ephemeris information and hot start
13. There are 4 LED indicators on the board to indicate the working status of the module.
14. LC29H(AA) GPS HAT has the following features:
-Support positioning enhancement systems (WAAS, EGNOS, MSAS and GAGAN) to improve positioning performance in service areas
-Supports EASY technology to use stored ephemeris, almanac data and other information for positioning when there is no signal, improving positioning and first positioning time
15. LC29H(DA) GPS/RTK HAT has the following features:
-Supports fast convergence dual-frequency RTK centimeter-level positioning, suitable for high-precision positioning of terminal equipment
16. LC29H(BS) GPS/RTK HAT has the following features:
-Supports GNSS original observation and correction data output, suitable for establishing RTK base stations
