Applications: Custom Embedded GIS Solutions, Autonomous Vehicle Navigation, Commercial Unmanned Vehicle (UAV / Drone) Installation

Description: The Zubax GNSS 2 is a very high performance GPS + GLONASS + Galileo concurrent receiver with integrated Barometer and Compass. It is an open-source receiver meant for users that have sensitive position requirements (commercial users; use in semi-urban canopy environments; use in situations where the least amount of GPS drift is desired). The Zubax GNSS 2 receiver is designed for a professional user that requires RF shielding for use in systems with nearby electronics. Through the redundant CAN bus, the receiver is capable of self diagnostic and failure detection making it an essential choice for mission critical applications. The Zubax GNSS 2 is a dramatic improvement over the original, revolutionary, proven Zubax GNSS which was released in 2014. Click here for a brief overview (PDF) to learn about what distinguishes the Zubax GNSS 2 as a professional-grade GNSS receiver.

Devices which are known to support UAVCAN peripherals:
 Pixhawk Autopilot Series (both PX4 and APM firmware): Pixhawk, Pixhawk 2 (Cube), Pixhawk 3 Pro, Pixhawk 4, Pixracer 
 Intel Aero 
 MindPX
 MindRacer

Technical Specifications:

Comparison to alternative receivers:
 Position Accuracy - 1-2 meters commonly observed versus industry standard of 2-5 meters (actual accuracy depends on your environment)
 Superior Drift Performance –Dramatically better horizontal drift versus conventional GNSS receivers especially in areas with urban or suburban canopy (buildings, tree coverage, or other obstructions) making it an ideal choice for commercial applications
 Incredible Number of Satellites Used – Compared with 3DRobotics (3DR) GPS modules (Lea-6H), the Zubax GNSS 2 can utilize more than twice the amount of visible satellites meaning that you’ll observe significantly improved position accuracy. Read the full report below which compares commonly known GNSS receivers. 

Pixhawk Compatible GNSS Receiver Paper: Read this report for a bench test comparison which illustrates the differences between the Zubax GNSS 2, Mayan Robotics NEO-M8N, 3DR GPS, Drotek NEO-M8T, and the Hex / Proficnc Here GNSS.

Suggested accessories (contact us for details or visit our store):
 Elevation Mast / Mounting Pole
 Protective Housing
 Connectivity Cables (Example: The Pixhawk autopilot requires a DF13 cable whereas the Pixhawk 2 requires a JST GH cable)
 Standalone Barometer Cover (if you don't intend to use the protective housing)
 Micro Termination Plug (required for use with most systems including the Pixhawk autopilot series)

Notice to Pixhawk Users Who Use PX4 Firmware (this does not apply to APM users): We have been made aware that CAN support on the original Pixhawk autopilot (FMUv2) has become limited due to the overwhelming migration of the PX4 development community to the Pixhawk 2 autopilot (FMUv3). If you intend to use this Zubax product on the original Pixhawk (FMUv2), feel free to obtain PX4 firmware release v1.4.4 from GitHub (click here) to achieve CAN functionality. Note that there might be other PX4 firmware editions that provide CAN compatibility and the one provided has been done by courtesy only. It is the responsibility of the end user to test and use open source autopilot firmware at their own discretion.
