Larger areas per launch
One launch maps up to 1,000 ha at about 10 mm/px or up to 300 km of corridor, so a whole job finishes inside one weather window.
Fadron Nimbus · Long-range VTOL drone
One operator launches Fadron Nimbus from any clearing and flies it up to 300 km with a survey camera, LiDAR or EO/IR gimbal on board, for mapping, surveying, inspection and ISR.
Why Nimbus
One launch maps up to 1,000 ha at about 10 mm/px or up to 300 km of corridor, so a whole job finishes inside one weather window.
Nimbus folds flat into one case and needs no tools or assembly. Its carbon-fiber airframe is the largest in its class that one person handles comfortably.
Nimbus lifts up to 4 kg, enough for the sensors clients pay for: a survey-grade camera, LiDAR, thermal and RGB together, or an EO/IR gimbal.
The Mapper price comes by email, and a demonstration flight comes to your site.
Coverage per flight
Six survey aircraft flown to one brief: 27 mm/px, 60% side overlap, each with the mapping sensor it is sold with and at its manufacturer's published maximum flight time. Nimbus flies a routine three-hour sortie, below its own maximum, and still covers the most ground by a wide margin.
Coverage = sensor width in pixels × ground sample distance × (1 − overlap) × cruise speed × flight time. Flight times and sensors are each manufacturer's published figures. Run it against any aircraft on the chart in our GSD and UAV performance calculator. Fadron's own 1,000 ha per flight is quoted at a finer survey resolution of about 10 mm/px, where every aircraft here scales down in the same proportion.
Fewer flights per job means fewer setups, fewer battery swaps and fewer days waiting on weather.
Applications
Each job flies on the same VTOL drone with one operator; only the sensor changes.
One operator flies topographic and cadastral surveys with a survey-grade Sony or Phase One camera and RTK or PPK positioning, covering large blocks before the weather turns.
Ask about surveyingA single flight maps up to 1,000 ha at about 10 mm/px, giving one consistent image set for orthomosaics and 3D models of large sites, towns and estates.
Ask about aerial mappingA YellowScan LiDAR unit on Nimbus maps bare ground under tree canopy, for terrain models, floodplains and power line vegetation checks across whole corridors and sites.
Ask about LiDAR mappingHighways, rail, pipelines and power lines are flown end to end, up to 300 km from one launch, and HALO AI scores roads and runways to ASTM PCI.
Ask about corridor inspectionMap open pits, haul roads and stockpiles across the whole site in one visit, so every volume report and progress check comes from the same surface model.
Ask about mine surveysNimbus maps crop health, irrigation and forest stands across whole farms and estates in one flight, with thermal and RGB or a multispectral camera fitted to order.
Ask about agricultureThermal cameras count herds and colonies across whole reserves in long transects from altitude, and Recon patrols for poachers with EO/IR detection and tracking on board.
Ask about wildlife monitoringNimbus Recon carries an EO/IR gimbal with a thermal camera for border and perimeter patrol, search and rescue, and wildfire watch, and keeps flying the mission when GPS is jammed.
Ask about ISR missionsName the mission and the sensor, and we reply with a specification and price.
In the field
Nimbus goes from the closed case to the flight line by hand: unfold the wing, set it down in any clearing, and it lifts off vertically.
Two configurations
Both fly the same carbon airframe on PX4 and QGroundControl. The payload and the software on board change with the mission.

Mapper is the survey configuration, for operators, surveyors and asset owners who map large areas.

Recon is the ISR configuration, for border, security and public safety teams who patrol large areas.

Integrated payloads


Atmolab and NextVision also fly on Recon. Bring another sensor and we integrate it.
Aircraft data and procedures ready for your BVLOS application.
Designed, built and flight-tested in Sofia, within the EU and NATO.
Logged on the Nimbus airframe that every production aircraft is built to.
A configuration built for US federally funded and government-connected work.

Production
Every Nimbus is laid up, assembled and acceptance-tested in the facility where it was designed.
The engineers who build it also support it: a new mount, a payload integration or a mission-specific parameter set is engineered in house, and spares come off the same line.
Questions
Nimbus maps up to 1,000 ha in one flight at about 10 mm/px, survey resolution for corridor and site mapping. In maximum-detail mode it flies lower and slower and maps down to 0.1 mm/px over a smaller area. We plan the flight around the deliverable you need.
Yes. Fadron's Nimbus Mapper flies topographic and cadastral surveys with RTK or PPK positioning and a survey-grade Sony or Phase One camera, or a YellowScan LiDAR unit where terrain sits under vegetation. One flight maps up to 1,000 ha at about 10 mm/px, so a whole survey block is captured in one weather window and one consistent dataset.
For large reserves, a long-range VTOL fixed-wing drone fits best, and Fadron Nimbus is built for that work. It takes off vertically from any clearing, flies 2.5 hours on a single battery or up to 4 hours with a second, and carries thermal and RGB cameras for animal counts. Nimbus Recon adds EO/IR anti-poaching patrols.
Yes. Nimbus is built for BVLOS work: one operator flies the whole corridor from one launch point, with no observers posted along the line. In the EU, BVLOS flights run under an operational authorization assessed with SORA, and we prepare that application with you, with the aircraft data and procedures it needs.
Yes. Nimbus Recon is the ISR configuration of Fadron's long-range VTOL drone, for border security, critical infrastructure, search and rescue, and wildfire. It flies up to 300 km, carries an NDAA-compliant EO/IR gimbal with a thermal camera, tracks targets on board, and keeps flying when GPS is jammed or spoofed.
Nimbus Recon keeps flying the mission. It fuses visual navigation with its inertial system, so it knows where it is without satellite signals and finishes the route. EASA ranks the Sofia flight information region fourth in the world for GNSS interference, and Nimbus is built and flown inside it.
Nimbus Recon is available in an NDAA-compliant configuration, down to its EO/IR gimbal with a thermal camera. Name the requirement when you request the quote and we build to it.
Nimbus ships ready to fly: the aircraft in your configuration, your payload integrated, flight-planning software, HALO AI integration and operator training, so your team flies it without us. It runs on PX4 and QGroundControl, so a crew that knows the open-source stack starts on familiar ground. Full hull and liability insurance can be added to the package.
Yes. We bring Nimbus to your site and fly a live demonstration over your own survey area, so you judge it on the ground you actually map.
Nimbus is in serial production in Sofia, so your aircraft comes off a running line. The delivery window is confirmed in writing with your quote and becomes part of the specification you sign.
