UK‑built VTOL drones.

Bhanexus designs and builds uncrewed aircraft. Our flagship ISR VTOL takes off from a 10 m square, cruises 30 km out on its wing, and keeps navigating when GNSS is jammed or spoofed.

ISR VTOL

A 2.43 m fixed-wing VTOL for intelligence, surveillance and reconnaissance, operated by a two-person crew without a runway or launcher.

  • Lift and cruiseFour lift motors for vertical take-off and landing, one front motor for wing-borne cruise at 17–20 m/s.
  • 30 km radiusElectro-optical and thermal imagery, day and night, with live video and onboard recording.
  • GNSS-denied navigationTerrain map-matching and dead reckoning keep it on track when satellite positioning is denied.

What goes into the aircraft

Every capability starts as a traceable requirement and ends as verified evidence, the way certified airborne systems are built.

Lift-and-cruise flight

Hover on four lift motors, transition autonomously to wing-borne flight on the front motor, and back again. A single lift-motor failure in hover has a defined, controlled response.

GNSS-denied navigation

Absolute position fixes from terrain map-matching, dead reckoning that drifts no more than 10% of distance flown, and a dual-band receiver to resist spoofing.

ISR payload

Daylight and thermal cameras on a stabilised gimbal, live video to the ground station, onboard recording, and automated object detection that marks targets for the operator.

Secure links and data

An authenticated control link, an end-to-end encrypted video downlink, encrypted onboard storage, and a low-signature mode that records on board and downlinks on demand.

Containment and assurance

Geofence, link-loss contingency and pre-flight launch inhibit, flown under UK CAA rules, with every requirement traced from mission need to verification.

Who is building it

“Safety-critical software is one discipline, whether it flies, drives or charges. Bhanexus points that discipline at uncrewed aircraft.” Bhanuprakash HP, Founder & Director

Sixteen years of control software delivery, from engine and emissions controls at Bosch and Mercedes-Benz to ADAS motion control at Jaguar Land Rover, high-voltage battery and power distribution software at Fortescue Zero, and DO-178C airborne software certification today.

Ten patents, and engineering teams of more than 50 people built and led.
