Today we present our first product - Zubax GNSS. It is a high-performance open source positioning module for outdoor environments with doubly redundant UAVCAN bus interface. It's the right choice for any UAV or robotic application where safety, positioning accuracy and cost efficiency are paramount.
Being UAVCAN-interfaced, Zubax GNSS can be used out of the box with any UAVCAN-enabled controller, such as Pixhawk. Detailed instructions about how to configure Pixhawk for use with Zubax GNSS can be found at our documentation portal (see the links below). At the moment, the native PX4 stack already has complete UAVCAN support implemented in the stable branch. The APM stack doesn't have support for UAVCAN at the moment, but there were some successful experiments with it earlier so it will be there soon as well. By the way, any cooperation from the APM developer community is highly welcome!
The image below shows the performance of Zubax GNSS in comparison with another popular GPS receiver (u-blox LEA-6H with 25 mm patch antenna). Notice the deviation map, position accuracy estimates and SNR. This was captured in a shallow urban canyon of a large city. Zubax GNSS is on the left (click to enlarge):
This video features a highly precise, fully automatic landing of a Pixhawk-powered quadrotor with Zubax GNSS:
P.S. Stay tuned for more UAVCAN-interfaced avionics. UAVCAN-enabled ESC and a UAVCAN-enabled something-quite-important are on their way to the market. Developers, please consider moving towards UAVCAN-centered ecosystem by supporting this protocol in your projects - learn more at uavcan.org.
