Collection: Multi-Band GNSS HATs for Raspberry Pi

High-performance GNSS HATs and modules for Raspberry Pi designed for precision positioning, navigation, and timing (PNT). Featuring multi-constellation support for GPS, GLONASS, Galileo, and BeiDou, with selected dual-band L1/L5 models for improved multipath mitigation and signal robustness.

The RTK HAT adds centimeter-level accuracy with RTK corrections. On both HATs an onboard supercapacitor keeps the receiver's backup memory alive for up to 4 hours without power, so it gets back to a fix in about 2 seconds.

Every GNSS HAT comes with open-source drivers, example projects and a ROS 2 package, so you spend your time on the application instead of on bring-up. Typical uses are robotics, UAVs, IoT tracking, surveying and embedded Linux.
