This is a Raspberry Pi GNSS HAT based on NEO-M8T with multi-constellation receiver support, as well as precise single-satellite timing feature. It supports concurrent reception of up to 3 GNSS (GPS, Beidou, Galileo, GLONASS) and augment systems like SBAS, QZSS, IMES, and D-GPS. It features accurate & fast positioning with minor drifting, low power consumption, outstanding ability for anti-spoofing & anti-jamming, and so on.

By simply attaching it onto the Pi, it is fairly easy to enable GNSS capability for your Raspberry Pi.
