Neso tracks above a rescue boat near a rocky Greek island. The original Pterops Control interface presents a coastal mission plan. Aircraft scenes are AI-generated design visualizations based on the updated development renders; software screens contain synthetic or simulated demonstration data. Products are in development.

Ready. Execute.
Supervise.
Know your fleet. Define the mission. Keep people in control. Three software roles built around the work of aircraft operators.
Pterops Fleet
Readiness starts with the whole fleet.
Know what is ready, what is grounded and what needs attention. Bring aircraft records, maintenance, crew qualifications and sortie release into one accountable workflow.
- Fleet readiness
- See aircraft status, configuration and grounding reasons in context.
- Maintenance & sustainment
- Connect inspections and work orders with components, stock, tools and battery health.
- Accountable release
- Bring crew currency, sortie preparation and signed release into the same record.

Pterops OS
From mission intent to recorded outcomes.
Connect approved intent to supervised execution. Verify signed requests, monitor operating limits and preserve a clear record of what happened.
- Verify the request
- Check signatures, permissions, freshness and replay protection before admitting commands.
- Supervise execution
- Connect accepted operations to the autopilot, with operating limits and process monitoring.
- Record the outcome
- Review what was requested and what occurred through command journals and telemetry.
Verify authority
Check signed requests against approved permissions and operating constraints.
Supervise execution
Connect accepted operations to the autopilot and monitor their progress.
Review outcomes
Preserve command activity and telemetry for a traceable mission record.
Pterops Control
Define the mission. Keep people in control.
Turn mission intent into a reviewed plan. Define areas, routes and constraints, organize aircraft teams and keep approval with the operator.
- Mission planning
- Build area, corridor and point missions with explicit exclusions.
- Human approval
- Review a specific mission version, with clear responsibility for approval.
- Evidence review
- Keep mission plans and records in context for the people responsible.

Different missions.
Shared foundations.
Your aircraft, your teams and your operational priorities. Explore how Pterops fits the work of industry, infrastructure, defence and government.
Industry & infrastructure
Aircraft readiness and reviewed mission workflows for asset inspection, corridor observation and distributed sites.
Explore this route 02 / ApplicationsDefence & government
Fleet sustainment, clear mission authority and recorded outcomes for ministries, agencies and operational teams.
Explore this routeLeo & Neso.
A wider view. A closer look.
Our aircraft concepts explore wide-area observation and closer inspection. Pterops is also being developed for assessed integration with your aircraft.
Explore the aircraft
Leo
Lift-plus-cruise VTOL
A fixed-wing aircraft concept for wide-area observation, combining vertical takeoff with wing-borne cruise.

Neso
Compact quadcopter
A separately launched quadcopter concept for closer inspection and observation, bringing a closer view to the mission.
Built around
the operator.
Synthmind develops human-supervised autonomous systems, starting with aircraft. Based in Greece, we are building software for customer fleet readiness, mission execution and operator control across industry, infrastructure, defence and government.
- Human authority
- Clear decisions. Explicit approvals. People remain responsible.
- Open architecture
- Documented interfaces and modular components create a path to assessed customer integrations.
- Traceable evidence
- Records that connect actions, decisions and outcomes.
