A ground-based control unit observes an unmanned aircraft from the outside, interprets the situation, and flies it using the same stick inputs a human pilot would use. We add nothing to the aircraft's electronics, its software, or its control system.
On a small airframe, every gram of computing and sensing is taken directly out of flight time. The smaller the aircraft, the less optional this becomes.
High temperature degrades exactly the high-performance semiconductors that on-board autonomy depends on. Placing the intelligence outside the environment is a structural answer, not an incremental one.
Where an aircraft may be lost or contaminated, keeping the intelligence off-board means the aircraft can be sent in without hesitation - and the capability survives when the aircraft does not.
An aircraft cannot see its own attitude, and cannot easily detect its own drift. A control unit observing from a third-person viewpoint can.
We work where conventional drone operation breaks down structurally: sites people cannot enter, sites where the aircraft cannot be assumed recoverable, and sites where GNSS does not reach.
Plant and infrastructure inspection - interiors and dense equipment areas where satellite positioning is unavailable and skilled manual piloting is currently required.
Disaster response - collapsed structures and hazardous areas, with a transportable control unit deployed from safety or from an unmanned ground vehicle.
Hazardous and extreme environments - inspection where the aircraft may not return.
Patent JP 7780684 B, granted November 2025. Its claims cover control of an aircraft by an external control device together with an operator device, suppression of control signals derived from dangerous operator input, handover of control authority between control devices via a shared coordinate frame, and individual control of multiple airframes.
In May 2026 we demonstrated the principle indoors: a micro airframe with no position-hold capability of its own was held in stable hover by a control unit outside it. The aircraft levelled itself and reported its attitude; position, altitude and heading were estimated from cameras outside the aircraft and delivered as stick input.
Outdoor operation and harsh-environment operation are unverified. The environmental range in which third-person observation remains viable - illumination, dust, occlusion, distance - is not yet characterised. Establishing it is our current research question.
