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

- 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

Lovely bit of kit! I was discussing the inclusion of an external baro within a GPS unit on another thread on here recently, and this definitely hits the mark! The pricepoint of this product however is what puts me off. If I was flying professionally, I'd definitely jump at this though. I have integrated a standard m8n (uart)/mag(i2c) with an i2c connected baro, all inside a (slightly modified) GPS puck on one of my quads, and this works beautifully for under $30 with APM 3.4dev. I can't really justify175 euros for one of these. Its a great product though - nice to see new sensors using digital bus for connectivity instead of basic UART.
Anyone who's struggling with the web store (it occasionally malfunctions during checkout, which happened to Justin), please reach to pavel.kirienko@zubax.com. The web store should resume normal functioning soon though. Sorry for the inconvenience!
DG, maybe you should consider switching to PX4 instead ;)
I'd love to try this, but with AC 3.4 stalled already by 3 months it probably won't happen, although I have 3.4 dev in the test quad; don't know if it has updated UAVCAN. I certainly hope we'll see 3.4 materialize this year, if ever.
Justin, there seems to be a transient issue with shipping indeed. We're looking into that; please check back later! Sorry for the inconvenience.
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.
@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 like it using UAVCAN but I wish it was 3*3cm for small racing quads.
