Skynode

Skynode is the flight-controller-and-mission-computer module built by Auterion , the Swiss-American drone software company founded by former PX4 maintainers. First released in 2019, the unit packs an autopilot and a Linux companion computer into a single board roughly the size of a deck of cards, intended to drop into fixed-wing, multirotor, and one-way attack airframes built by third-party manufacturers. The pitch from the start has been an open, NATO-friendly alternative to closed Chinese flight stacks: one common software base across many airframes, same ground-control software, same encrypted command-and-control plane.

The module’s autopilot side is a hardened build of PX4, the open-source flight stack Auterion’s founders helped create. Sitting alongside it is a Linux mission computer that runs AuterionOS and exposes a payload bus for cameras, lidars, and AI inference accelerators — the bus that more recent terminal-guidance and target-lock features hang off. Command-and-control runs over an encrypted MAVLink-derived link, paired in practice with mesh radios from Silvus or Doodle Labs. A smaller derivative, Skynode S, strips the package down to the essentials needed for cheap attack drones, and is the variant most often cited in current Ukraine deliveries.

Operators include the United States, where Skynode-equipped airframes from Skydio, Teal, and Quantum Systems sit on the Defense Innovation Unit’s Blue UAS Cleared list, and Germany, which fields the Quantum Systems Vector reconnaissance drone built around the module. The largest publicly disclosed deployment is Ukraine: in late 2024 Auterion announced a contract to deliver 33,000 Skynode S units for AI-enabled strike drones, with deliveries continuing through 2025. The same hardware underpins one-way attack drones procured by the U.S. Department of Defense under a separate award announced in 2024 for autonomous terminal-guidance kits.

Development around the module has accelerated since combat use began. Auterion’s Nemyx swarm-autonomy stack runs on Skynode-class hardware, coordinating multiple drones from a single operator station, and the company has used Ukrainian feedback to iterate on jam-resistant guidance and last-mile target lock. Skynode S in particular has become the reference implementation for what a Western “smart kamikaze” flight controller looks like in 2025 — open-architecture enough to slot into many airframes, secure enough to clear NATO procurement, and cheap enough to be expendable.
