Raspberry Pi LC29H(AA) GPS HAT expansion board (25278)

The Raspberry Pi LC29H(AA) GPS HAT (25278 ) is a high-precision GPS module specially designed for use with the Raspberry Pi single board computer. It works on the basis of L1+L5 dual-band positioning technology, which allows you to get extremely accurate geographic data.

This module supports the optional RTK (Real-Time Kinematic) function, making it an ideal choice for applications that require the highest accuracy and reliability of location. As a result, you can use it for navigation, mapping, autonomous vehicles, drones, and many other applications where accurate location is essential.

The LC29H Series Dual-band GPS module for Raspberry Pi is a powerful and reliable tool for obtaining highly accurate geographic coordinates, opening up a wide range of possibilities for your navigation and positioning projects. It is ideal for real-time tracking systems and cost-effective sharing applications, helping to develop applications such as drones, smart farming equipment, shared two-wheeled vehicles, and more.

Key features:

• Has a standard Raspberry Pi 40PIN GPIO expansion connector and supports Raspberry Pi series boards, Jetson Nano
• Supports simultaneous tracking of dual-band L1+L5 satellite signals, reducing the multipath effect in urban canyons and improving positioning accuracy
• Supports simultaneous reception of multiple GNSS systems (GPS, BDS, GLONASS, Galileo and QZSS) while maintaining low power consumption
• Supports positioning augmentation systems (WAAS, EGNOS, MSAS and GAGAN) to improve the positioning performance of service areas
• Supports EASY technology to realize positioning using stored information, such as ephemeris and almanac data, when there is no signal, and improve positioning and time to first fix
• Has a built-in low-noise amplifier and acoustic surface filter to realize high sensitivity of -165 dBm and improve anti-interference performance
• Supports multi-frequency active jamming, effectively suppressing or eliminating narrowband signal interference (WiFi/2/3/4/5G) to ensure navigation accuracy
• Support for A-GNSS (auxiliary GNSS), reducing the time to first fix (TTFF) with a cold start when turned on to 5 seconds
• Supports QGNSS software, easy customization of various module functions
• Has a built-in battery holder, supports ML1220 rechargeable battery, for storing ephemeral information and hot start
• Built-in 4 LED indicators for module operation status
• Comes with online development resources and manual (Python examples for Raspberry Pi/Jetson Nano)
