QGroundControl provides full flight control and vehicle setup for PX4 or ArduPilot powered vehicles. It provides easy and straightforward usage for beginners, while still delivering high end feature support for experienced users.
To download and install software please refer to the relevant documentation for details.
Aside from Zubax GNSS 2 itself and the autopilot it will be connected to, the following parts will be needed:
- UAVCAN Micro patch cable (or an adapter cable, depending on the type of CAN connectors used in the autopilot hardware).
- UAVCAN Micro termination plug.
Please contact your supplier for ordering information. Alternatively, customers can choose to manufacture the needed cables/plugs on their own in order to suit some custom needs, in which case they should refer to the relevant documentation for details.
Since Zubax GNSS 2 can be powered directly from the bus, the electrical connections are quite simple:
- Connect Zubax GNSS 2 with Pixhawk using the appropriate cable. In case you’re using a non-redundant CAN interface (which is the only available option for Pixhawk v1), only CAN1 must be used, leaving CAN2 empty.
- Terminate the CAN bus using the termination plug.
Configuring the PX4 flight controller
Don’t forget to perform compass calibration when done. If the autopilot reports issues with high magnetic field offsets, set the parameter
mag.scaling_coef on Zubax GNSS to approximately
0.6 and try calibration again
