GNSS 2

High-performance board-level positioning module with compass and barometric altimeter for robots and unmanned vehicles.

Zubax GNSS 2 is a multipurpose high-performance board-level positioning module interfaced via CAN bus, USB, and UART. It includes a multi-system concurrent GPS + GLONASS + Galileo receiver, a high-precision barometric altimeter, and a 3-axis compass with thermal compensation. Zubax GNSS 2 supports a variety of standard protocols, which ensures compatibility with third party software and hardware: DroneCAN, NMEA 0183 (over USB and UART), and the u-Blox M8 binary protocol.

Applications

  • Positioning module for unmanned vehicles (aerial, ground, underwater, etc) and robots.
  • General-purpose embedded positioning module.

Features

Sensors

  • State-of-the-art concurrent GPS + GLONASS + Galileo receiver u-blox MAX-M8Q.
    • Full RF shielding of the GNSS circuits ensures reliable operation in high-EMI environments.
    • 35 mm high gain patch antenna with large ground plane for reliable reception even in deep urban canyons.
    • Analog front end with LNA and SAW ensures high noise resilience.
    • Supercapacitor-based backup power source enables low time-to-first-fix (a few seconds).
    • Up to 15 Hz solution update rate.
  • High precision digital barometer TE Connectivity MS5611.
    • Altitude resolution 10 cm.
  • High precision 3-axis digital compass STMicroelectronics LIS3MDL with thermal compensation.

Interfaces

  • Doubly redundant CAN bus interface (UAVCAN v0).
    • Continuous self diagnostic and failure detection outputs.
    • Remote reconfiguration.
    • Can be used in non-redundant mode as well (one interface will be inactive).
    • Firmware upgrade.
  • USB (virtual serial port interface).
    • NMEA output for all sensors.
    • Direct access to the u-blox module.
    • Diagnostics and configuration via the command-line interface.
    • Firmware upgrade.
  • UART
    • NMEA output for all sensors.

General

  • Top notch positioning performance.
  • Extensive, continuous self diagnostics and failure detection make Zubax GNSS a favorable choice for mission-critical applications.
  • Compact size.
  • High quality assurance:
    • Every manufactured unit undergoes a rigorous testing procedure. The testing log for each produced unit is available on the web.
    • Protection against unlicensed (counterfeit) production by means of a digital signature installed on every manufactured unit.
