.jpg?1595612920820)
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.
- 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
- 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
- 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)
