NEO-M8T GNSS TIMING HAT

GNSS module based on NEO-M8T for Raspberry Pi, single-satellite timing feature

accurate & fast positioning with minor drifting, low power consumption, outstanding ability for anti-spoofing & anti-jamming

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.

Features at a glance

Precise timing feature, high availability even with one single satellite
High dynamic range radios with both analog and digital interference mitigation, supporting applications in wireless communications equipment
Multi-constellation receiver support, concurrent reception of up to 3 types of GNSS satellite systems from GPS, Beidou, Galileo, and GLONASS, and still retains low power consumption
Augment systems support, including SBAS, QZSS, IMES, D-GPS, improving the positioning performance of service location
