L1 GNSS HAT

L1 GNSS HAT for Raspberry Pi

A professional-grade GNSS HAT based on the u-blox NEO-M9N chip. This board delivers reliable, standard-precision positioning for robotics, drones, time servers, and outdoor navigation systems.

Key Features:

• GNSS: Reception of GPS + QZSS, Galileo, GLONASS, BeiDou, jamming and spoofing detection, position accuracy: 2m CEP
  
• SPI Communication: Fast, low-latency integration with Raspberry Pi for real-time GNSS data, up to 25 Hz position refresh rate.
• Timepulse pin connected to GPIO: can be used as interrupt source for your app or as PPS essential for network time servers, SDR, or sensor fusion.
• Geofencing: up to 4 circular zones
• Geofence Relay Output: Trigger devices or alerts based on configurable geo-location zones.
• Hot Start: Onboard supercapacitor allows hot-start procedure (2 seconds to acquire fix) up to 4h after power loss
• USB-C: Direct access to u-blox
• External Antenna: SMA connector, 3,3 V
• Open-Source Software: GitHub repo with user-friendly library with many examples, link: https://github.com/jimmypaputto/GnssHat

Applications:

• Robotics & autonomous navigation
• Time servers
• Sensor fusion with PPS
• Geofencing security systems
• Environmental & location-based data logging
• DIY drones & RC vehicles
• Outdoor tracking and telemetry

Package Includes:

• 1x GNSS HAT for Raspberry Pi (NEO-M9N based)
