Hi everyone,

3689685346?profile=originalWe're proud to announce that Zubax GNSS 2 is now available. Zubax GNSS 2 is a compact multipurpose high-performance positioning module interfaced via redundant CAN bus, USB, and UART. It includes a state-of-the-art multi-system GPS/GLONASS receiver, a high-precision barometric altimeter, and a 3-axis compass with thermal compensation. Zubax GNSS 2 supports variety of standard protocols, which ensures compatibility with most of existing software and hardware: UAVCAN (over CAN bus), NMEA 0183 (over USB and UART), and u-Blox M8 protocol.

Zubax GNSS 2 is the successor of well-received Zubax GNSS v1; it features an upgraded GNSS receiver (latest u-Blox M8Q), smaller form-factor (55x55 mm), and a higher gain antenna. Like it's predecessor, Zubax GNSS 2 features high noise resilience thanks to the RF shielding and good PCB design.

Our website contains tutorials that demonstrate how to use Zubax GNSS 2 with Pixhawk (PX4, ArduPlane 3.5.1, ArcuCopter master), with GIS software, and with non-UAVCAN enabled systems (e.g. lower-end autopilots).



  • Operating temperature: -30 to +60 °C


  • State-of-the-art concurrent GPS/GLONASS 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 urban canyons
    • Analog front end with LNA and SAW ensures high noise resilience
    • Backup supercap enables low time-to-first-fix (a few seconds)
    • Up to 15 Hz update rate
  • High precision digital barometer Measurement Specialties MS5611
    • Altitude resolution 10 cm
  • 3-axis digital compass with thermal compensation


  • Doubly redundant UAVCAN
    • Continuous self diagnostic and failure detection outputs
    • Configuration
    • Can be used in non-redundant mode as well (one interface will be inactive)
    • Firmware update
  • USB
    • NMEA output for all sensors
    • Direct access to the u-blox module
    • Diagnostics and configuration via command-line interface
  • UART
    • NMEA output for all sensors

  • Thank You for explanation.

    Best regards,


  • Serge, you can freely re-use our firmware with your custom hardware, as long as you're complying with GPL v3. Cheers!

  • Приветствую разработчиков GNSS-2. Нам понравился ваш модуль, но мы-бы хотели изготовить его в другом форм-факторе. Последуют ли вогражения от вашей команды (компании) если мы самостоятельно изготовим всю электронную начинку GNSS-2 для своих целей, но сохраним обратную совместимость с вашим программным обеспечением?

    С уважением,

    Thanks for the quick reply! Really looking forward to it. Would be great if you could drop me a line if you have some units ready for testing.

  • Thanks for the question Thorsten, there's something like that coming up soon.

  • T3

    Nice design! What about a version with the M8N instead of the M8Q for recording raw GPS data?

  • Hi William, you need ArduCopter v3.4 at least. Please proceed to the product forums here - https://productforums.zubax.com/viewforum.php?f=4. Thanks!

  • I am trying to configure this zubax gps and am having problems. While looking at the Params list in Mission Planner I can not locate the BRN_CAN_ENABLE parameter on the latest firmware. Please help.
  • Justin, it must be a temporary issue, sorry about that. Should be resolved any day, if not already.

  • How come your store says there are 190 units available but on orders put through a couple weeks ago we call and you tell us you don't have any stock for another 7 to 10 days.
