Auterion Skynode

Skynode is a powerful flight computer that combines a mission computer, flight controller, video streaming, networking, and cellular connection, in a single tightly integrated device.

Auterion Skynode (Enterprise)

The onboard software is Auterion OS, consisting of an enterprise-hardened version of PX4 running on the flight controller, and an operating system with advanced management software running on the mission computer. The OS is managed by Auterion in production, with customer applications running as "add ons" in a safe sandbox within the mission computer.

Auterion OS and Skynode allow seamless integration with Auterion's other software and fleet management products.

Skynode with Vanilla PX4

Skynode comes with an Auterion-managed release of PX4. If you would like to try a more recent PX4 flight kernel, you can install the upstream "vanilla" PX4 from PX4/PX4-Autopilot.

Upstream PX4 will generally work, with the following caveats:

  • Configuration for your exact product may not be present. You may lose the configuration for ESCs, batteries, sensor configuration, and so on.
  • Some parameters might have different default values in the PX4 release shipped with Auterion OS.
  • Features accessed by vendor-specific customisations running on the companion computer may not be present in PX4.
  • Auterion supports Skynode running its own Auterion-managed version of PX4.

Building/Uploading Firmware

PX4 px4_fmu-v5x binaries for Skynode are built from source using the normal developer environment and build commands, and are uploaded using either upload_skynode_usb or upload_skynode_wifi upload targets.

upload_skynode_usb and upload_skynode_wifi connect to Skynode via SSH over a network interface using the default (fixed) IP addresses for USB and WiFi, and upload a TAR compressed binary to the mission computer. The mission computer then decompresses the binary and installs it to the flight controller.


SSH and TAR are needed to use these upload targets, but are expected to be present by default on Ubuntu and Ubuntu running on Windows in WSL2. On macOS you should first install gnu-tar.

You will need to enter the password for the Skynode developer image password twice during the upload process.
