Technical Specifications for Drone Building Inspection
Our FSS3 Flying Sensor drone, designed for building inspection and maintenance, boasts a multitude of advanced capabilities, including:
Centimeter-level Accuracy: Thanks to its RTK GPS, this inspection drone system can navigate to extremely precise locations, allowing it to pinpoint anomalies on production machinery or buildings by positioning its camera as close as 50 cm from surfaces.
Exceptional Stability: The FSS3 remains stable even in strong gusts of wind up to 70 km/h and heavy rain.
All-Weather Operation: The FSS3 can operate in any weather or temperature conditions, from -10°C to 40°C.
Adapted Thermal Payloads: Equipped with suitable thermal cameras to detect heat sources, for example.
Integrated Waypoint System: The drone features an integrated waypoint system within the HMI (Human-Machine Interface) software for high precision, along with a “Step-by-Step” control mode for semi-automatic piloting.

Since the advent of drones, and thanks to our professional drone pilots and technical innovations, applications in expertise and inspection have evolved significantly. Methods are now more numerous, less costly, and, most importantly, more precise.
Building Inspection Applications of the Flying Sensor Drone
Our Cominthesky Flying Sensor S3 inspection drone is capable of handling a wide range of applications:
Inspection of smoke detectors inside buildings
Incinerator inspection
Outdoor or indoor factory inspection
Pipeline inspection
Chimney inspection
Bridge inspection (all sides)
Ground topographical surveys
Volume calculation, 3D modeling
Thermal inspection of buildings
And more…
While this drone system is versatile, the Flying Sensor’s technical specificities set it apart for precision inspections, allowing it to fly in close contact with structures when necessary.
Focus on Drone Inspection of Buildings and Bridges
Cominthesky provides an inspection drone designed to simplify roof and building inspection operations using an onboard thermal or RGB camera.
Equipped with a protective cover and centimeter-level precision, the FSS3 drone is a game-changer for these challenges. It can fly in close proximity to structures with maximum centimeter precision without causing any damage or putting itself at risk. Importantly, all inspections can be performed without interrupting operations in the inspected area.
This capability also extends to maintenance inspections of towers, monuments, viaducts, pipeline networks, tunnels, beams, lightning rods, water towers, chimneys, relay antennas, roofs, frameworks, bells and bell towers, tall buildings, places of worship, and various other structures.

Focus on Thermal Inspection by Drone
Our inspection drone is also capable of detecting cracks issues, verifying building insulation, and identifying thermal malfunctions in homes, solar panels, and any other heat-emitting structures. Infrared thermography by drone offers an ideal solution for these types of inspections. Our team of drone experts has demonstrated through thermal studies on houses that our technology is fully operational for detecting temperature differences across a given site.

Guaranteed Safety with Propeller Guards: Unlike other aerial methods, this drone poses no risk of damaging structures.
Key Differentiators of the Flying Sensor for Drone Inspection
The Flying Sensor’s patented carbon protective shield, specifically designed and developed for this drone, allows it to fly in direct contact without any risk of damaging either the drone or the structure being inspected.
The drone can adhere closely to the building’s surface, enabling inspection with perfect stability and record-breaking precision due to the camera’s proximity, typically around 50 cm from the inspected surface.
Industrial Drone Inspection
Our drone system performs flawlessly indoors, making it especially useful for inspecting tubes or cables located at height. The FSS3 drone, equipped with its protective shield, can carry out inspections without risking damage to the drone itself.
This inspection drone is also ideal for maintenance and inspection of towers, monuments, viaducts, pipeline networks, tunnels, beams, lightning rods, water towers, chimneys, relay antennas, roofs, frameworks, bells and bell towers, tall buildings, places of worship, and various other structures.
Industrial clients now have the most efficient solution to move forward quickly, save time, and reduce costs.
