Defence companies in Switzerland

Builds the operating system and autonomy software that turns commercial drones into coordinated swarms for defence and enterprise fleet operations.

AuterionOS

The onboard operating system for autonomous drones and ground vehicles. Vendor-independent by design and built on PX4 and open standards, it runs across fleets of mixed-manufacturer vehicles, providing a consistent experience for autonomy, comms, sensors and apps. New capabilities can be deployed as apps without hardware changes.

Skynode X

An all-in-one autopilot and mission computer that integrates flight control, a mission computer and LTE connectivity into a single module. Skynode X gives any drone or robot immediate access to the full Auterion software stack — mission planning, live video, cloud analytics and predictive maintenance — without assembling separate components.

Skynode S

A compact, cost-effective version of the Skynode hardware platform designed for volume deployment. With over 50,000 units in service, it is the most widely deployed secure control module for autonomous aerial systems and serves as the hardware foundation for Nemyx swarm operations.

Nemyx

Swarm coordination software that links autonomous drones into a single, resilient combat force. Built on AuterionOS and optimised for Skynode S, Nemyx allows one operator to strike multiple targets simultaneously and maintain mission continuity even when GPS and video links are jammed. It integrates with existing fleets without hardware replacements.

Builds remote-controlled platforms for humanitarian demining and explosive ordnance disposal, deployed across conflict zones from Ukraine to Iraq and Colombia.

Builds robotic spacecraft that capture and deorbit defunct satellites and space debris for ESA and national space agencies.

ClearSpace-1

ESA-contracted mission to capture and deorbit the defunct PROBA-1 satellite using four robotic arms, targeting launch in the second half of 2026. It will be the first removal of an unprepared, non-cooperative space object from orbit, demonstrating the core technologies needed for recurring debris removal services.

PRELUDE

A two-spacecraft demonstration mission being developed with ESA's Space Safety Programme, targeting launch in 2027. The two craft will carry out complex autonomous rendezvous and proximity manoeuvres in real orbit, validating the navigation and sensor systems that underpin future inspection and debris removal operations at scale.

CLEAR

The UK's first Active Debris Removal mission, funded by the UK Space Agency, targeting the removal of two derelict UK-registered satellites from low Earth orbit above 700 km altitude. ClearSpace completed Phase 2 in May 2025, demonstrating key capture technologies and de-risking the mission ahead of the operational phase.
