NEO-M8T GNSS TIMING HAT For Raspberry Pi, Multi-Constellation Receiver Support, Single-Satellite Timing Feature

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 augments systems like SBAS, QZSS, IMES, and D-GPS. It features accurate & fast positioning with minor drifting, low power consumption, the 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 analogue 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
  • A-GNSS (Assisted GNSS) support, reducing the first positioning time when powered up, improving the acquisition sensitivity
  • Features -167dBm navigating sensitivity and the outstanding ability for anti-spoofing & anti-jamming, supports geo-fencing
  • Supports U-Center, an easy way to config the module
  • Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
  • 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
  • Comes with development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32)
