Zubax GNSS 2 - high-end positioning module for UAV and robotics

Hi everyone,

We'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).

Features

  • Operating temperature: -30 to +60 °C

Sensors

  • 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

Interfaces

  • 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

Very nice! Now available in North America, and with a 50cm cable available to boot.

Great news. And first with integrated (external) barometer to my knowledge.

Any support for baro failsafe/glitch integration and failover  with on-board Pixhawk baro?

Hi Olivier,

Not sure about APM, but PX4 does support automatic sensor fail-over: should Zubax GNSS 2's embedded barometer (or compass) fail, the autopilot will switch to the internal sensor automatically.

Is this plug and play for the pixhawk ?

Comment by Tony K on March 23, 2016 at 12:20pm

Also is there any 3D covers available ?

Tony,

Is this plug and play for the pixhawk ?

Virtually yes, you just need to make sure that: 1. You're using recent enough firmware on your Pixhawk; 2. UAVCAN support is enabled. All of this is covered here: https://docs.zubax.com/zubax_gnss_2/tutorials/using_with_pixhawk

Also is there any 3D covers available ?

Yes! Follow this link: https://github.com/Zubax/zubax_gnss/tree/master/hardware/3d_printin...

I like it using UAVCAN but I wish it was 3*3cm for small racing quads.

@Olivier, yes, ArduPilot supports baro failover, plus you can choose which baro is your primary. I fly one of the earlier v1 versions of this GPS on a heli with the external baro as the primary.

I don't have one of the v2 units, but I'd be surprised if it didn't work just as well as the v1

I have flown the v2 module with ArduCopter (master) an can confirm that the new module is working nicely and performs very well. It is almost plug-and-play with APM: after setting the params BRD_CAN_ENABLE to 2 and GPS_TYPE to 9, it is auto-detected as primary GPS on next boot. One thing to note is the exceptional lock performance: it usually has a low-HDOP 3D lock well before APM has finished booting.

Unfortunately, ArduCopter 3.3 still relies on a very outdated UAVCAN stack, hence there is no support for recent UAVCAN components in stable ArduCopter yet.

Looks like it is not possible to ship to Canada on the website.
