This is a GNSS HAT for the Raspberry Pi based on the u-blox NEO-M8T with multi-constellation receiver support as well as a precise single-satellite timing feature.

The HAT supports concurrent reception of up to 3 GNSS (GPS, Beidou, Galileo, GLONASS) and augmented 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!

Features

  • 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 yet still retains low power consumption
  • Augment systems support, including SBAS, QZSS, IMES, D-GPS, improving the positioning performance of service location
  • A-GNSS (Assisted GNSS) support, reducing the first positioning time when powered up, improving the acquisition sensitivity
  • Features -167dBm navigating sensitivity and outstanding ability for anti-spoofing & anti-jamming, supports geo-fencing
  • Supports U-Center, an easy way to config the module
  • Raspberry Pi 40-pin GPIO extension header
  • Breakouts the module's UART and I2C interface, for connecting with host boards like Arduino/STM32
  • Baudrate range: 4800~921600bps (9600bps by default)
  • Supports DDC (I2C compliant) interface: up to 400KHz (max)
  • Onboard battery holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts
  • 4x LEDs for indicating the module operating status
  • Online development resources and manual (examples for Raspberry Pi/Jetson Nano)
