Service 02
Flight software & firmware development
From the PX4 stack to dedicated control logic.
We customise the PX4 ecosystem and develop tailored modules, control logic and fail-safe behaviours, with Software-in-the-Loop simulation backing every change.
Strengths
- Advanced PX4 configuration and tuning for multirotor, VTOL and fixed-wing
- Custom modules and airframes, mixers and hover/cruise transition handling
- Dedicated fail-safe logic: link loss, low battery, geofencing
- MAVLink integration and onboard digital buses (DroneCAN / Cyphal)
Between open-source flexibility and safety-critical rigour
The PX4 ecosystem guarantees compatibility with standard ground stations (QGroundControl) and an active community. We extend it where needed:
- Control & transition — tuning of the attitude loops, transition handling for VTOL, mixers for non-standard configurations.
- Safety — defining and verifying behaviour under partial failure, command-link loss or geofence trigger.
- Onboard integration — dialogue between autopilot, companion computer and actuators over robust digital buses.
Every change is tested first in SITL simulation and then in the field, step by step.
Typical deliverables
- Versioned, documented PX4 configuration
- Any custom firmware modules with their source code
- A SITL simulation scenario for repeatable testing
