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: UAVCAN (over CAN bus), 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).
    • 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.

Zubax GNSS suddenly stopped working?

I’ve been using a GNSS V2.2 without issue on my pixhawk cube 2.1 with the AP 3.7. I plugged it in today and it won’t pick up any sats. I pulled it off the unit and connected it to Ucenter. Still no GPS sats are found. I have another Zubax from a different drone, plugged it into the cube and it works…

Cube with ChibiOS won't initialize UAVcan compass with onboard power?

@rbachtell and I are experiencing the same issue with our Cube 2.1 flight controllers on ChibiOS with the Zubax GNSS. Randy is running the latest master of AP, and I’m running 3.6.5. When we power up the drone via battery power and the cube power module, the Zubax’s on-board compass will not initia…

Second GNSS Zubax gone dead after some time

We bought a total of 3 Zubax GNSS so far. The first one worked for a couple of months than it died, wouldn’t make a fix anymore. Connected to U-Center too and same, no sats picked up. We sent that unit back and bought 2 new ones. The new ones worked good for 3-4 months than one of the two started to…
