Engineering that survives the field
Three things decide whether an unmanned aircraft comes home: what the flight control does when the link drops, what the navigation does when GNSS is jammed, and whether the airframe was designed for the wind it actually flies in.
Flight control — developed in-house, triple-redundant
The flight control system is our own design. Three independent sensor sets work in parallel, arbitrate every decision and back each other up; the recovery behaviour is defined at firmware level rather than configured by the operator. On heavy-lift platforms a lidar channel adds obstacle avoidance during approach and slung-load work.
- Three mutually independent sensor sets: barometric altitude, inertial measurement, navigation positioning and heading
- Independent operation with arbitration — the majority decision wins
- Mutual backup: a single sensor failure does not end the flight
Geo-fencing written into firmware
No-fly boundaries are stored as binary tables inside the flight-control firmware. They cannot be edited from the ground station, and they cannot be cleared by a field technician. This is a deliberate constraint: the boundary survives a lost link, a corrupted mission file and a change of crew.
Navigation without GNSS
When satellite signals are jammed or spoofed, the aircraft neither drifts nor drops the mission. Dedicated anti-jam sensors and a closed-loop pose algorithm keep it stable and on task; the return, when called, is flown under control along the recorded route.
- Four-constellation receivers: BDS, GPS, GLONASS and Galileo
- Dedicated anti-jam, anti-spoof sensors that detect interference and deception
- Closed-loop pose algorithm holding attitude and altitude on inertial and barometric references
- Visual-inertial fusion and terrain matching as the fall-back position source
- Controlled return along the recorded route, not an uncontrolled drift
Coordinated lift across aircraft
The P-BOX payload controller links two, four or eight aircraft onto a single slung load. Thrust is distributed in real time, swing is actively damped, and release is commanded from one station. In practice this turns a 200 kg platform into a 760 kg lift capability without a new airframe.
What we build, and what we integrate
We are precise about the boundary. Airframe, flight control and imaging systems are developed in-house. Propulsion units, radar and data-link subsystems are integrated from qualified suppliers and validated against our own acceptance criteria — we do not claim to manufacture them.
