AuterionOS

AuterionOS is a drone operating system developed by Auterion , the Zurich- and Arlington-based software house founded in 2017 by Lorenz Meier, the original maintainer of the open-source PX4 autopilot. Released commercially in 2018, AuterionOS extends PX4 into a full software stack for the airframe, the payload, and the ground station, and it ships on Auterion’s own Skynode flight-control module as well as on third-party hardware that has integrated the SDK. Its role in the field is to give a heterogeneous fleet of small drones — built by different manufacturers, often in different countries — a common autopilot, a common payload interface, and a common command-and-control plane.

The technical core is a MAVLink-native autonomy stack tied to the Skynode compute module, which couples a flight controller, a Linux companion computer, secure boot, encrypted storage, and an LTE/5G radio in one sealed unit roughly the size of a deck of cards. Vehicle manufacturers integrate Skynode and inherit the operating system without rebuilding the autopilot themselves. On top of the autopilot, the AuterionOS payload SDK lets sensor and effector vendors expose gimbals, EO/IR cameras, mesh radios, computer-vision modules, and warhead triggers through a uniform API, and a separate AI/vision runtime hosts onboard models for target tracking, terminal-guidance lock, and navigation in GPS-denied environments. The Auterion Mission Control ground-station application — and a Suite back-end for fleet management — sit on the operator side of the same stack, so a unit can fly mixed airframes from one screen.

The operating system is in service with the United States Department of Defense, where Skynode-based airframes appear on the Defense Innovation Unit’s Blue UAS list, and with the German and Swiss armed forces. Its largest operational footprint is in Ukraine, where Auterion has shipped tens of thousands of strike-kit Skynode units under contracts coordinated with the U.S. Department of Defense and announced through 2024 and 2025; Ukrainian units have used AuterionOS-based one-way attack drones against Russian armour and logistics targets, and the company has publicly committed to delivering 33,000 AI-guided strike kits in 2025. Auterion has also pushed into swarm operations through its Nemyx product, which layers cooperative-targeting behaviour on top of AuterionOS and is being trialled with Western customers.

Variants of the platform now span ISR quadcopters, fixed-wing loitering munitions, and ground robots, with the company positioning AuterionOS as the Western-aligned alternative to closed manufacturer stacks and to Chinese-built consumer flight controllers.
