Risk to people
Confined-space entry means permits, safety gear and standby teams, in spaces that are dark, dusty and sometimes structurally unstable.

Underground mines. Tunnels. Boilers. Tanks. The most dangerous places to inspect are exactly where ordinary drones fail.
Costly downtime
Inspecting a boiler or tank often means shutting the facility down and building scaffolding. The stoppage costs more than the inspection.
GPS drones drift
Commercial drones lose their position indoors, drift out of control and hit walls with exposed propellers. Skyline was built for exactly this.
Designed for confined spaces
Compact. Caged.
Completely aware.
GPS-free navigation
LiDAR-Inertial SLAM fuses 360° laser scans, precise to within 2 cm, with the IMU to hold position without GPS, even underground.
Collision-tolerant
A cage-ball frame of carbon fibre surrounds the drone. It can touch walls without falling, and is safe near the operator.
Actionable data
4K inspection video plus a 3D point cloud you can use to measure distance, volume and structural change.
Interactive 3D
Explore every angle.
Rotate the L-490, switch between front, side and top views, and see where each sensor sits. Turn the propellers and hover motion on or off.

One complete
3D map.
Under a dense forest canopy, inside a culvert or across a factory floor, Skyline scans as it flies and hands you a full point cloud when it lands.
Technology
Built in-house.
From the sensor stack to the screen.
An onboard NVIDIA Jetson Orin runs SLAM on LiDAR and IMU data, then sends a position estimate to the flight controller, which fuses it with its own IMU data to fly without GPS. Video, the growing map and telemetry stream to the operator over a 2.4 GHz link.

We flew the same airframe with and without LiDAR navigation. LiDAR made position hold roughly three times tighter.
Applications
Where it works.
Every test site was chosen to match real customer conditions: dark, narrow, GPS-denied, or full of obstacles.
Mining
Underground mines
Tunnels, stopes and shafts too risky to enter. Map areas that are unsafe for people.
Energy & process
Power, oil & gas
Boilers, tanks, stacks and large pipes, inspected without scaffolding or long shutdowns.
Coal & bulk
Warehouses & domes
Fly between racks and measure stockpile volume under a roof, where GPS drones cannot fly.
Infrastructure
Tunnels & culverts
Narrow channels over water, bridges and public tunnels, mapped end to end.
Manufacturing
Plants & steel structures
Roofs, steel frames and machine rooms. Check bolts, joints and corrosion up close.
Survey
Under dense canopy
Weak GPS beneath trees is no problem. Stable navigation outdoors as well as in.
Workflow
Fly in. Watch live.
Measure and report.
Fly in
The operator flies the drone into the space from outside. LiDAR keeps it steady without GPS.
Watch it live
Video, the growing 3D map, battery, flight mode and telemetry on one tablet screen. Designed for field crews, not programmers.
Measure & report
Open the point cloud on a PC to measure distance, volume and structural change over time.
Output
Every column.
Every floor. Mapped.
Field validation
Measured to the millimetre.
On a 20 m industrial rail structure, Skyline captured LiDAR and high-resolution camera data in one mission. We then compared the results with other inspection methods.

FAQ
Questions from
inspection teams.
How does it fly without GPS?
A 360° LiDAR and an IMU feed a SLAM algorithm running on an onboard NVIDIA Jetson Orin. The Jetson Orin sends its position estimate to the flight controller, which fuses it with its own IMU data. No GPS is needed. The LiDAR measures distance to within 2 cm, so the drone holds a steady position indoors or underground.
How long can it fly?
About 8 minutes per battery. That covers one spot inspection, such as one boiler room or one tunnel segment. Longer endurance is our current development priority.
Who can operate it?
The ground-control app is designed for field operators, not programmers. Video, the live 3D map, battery and flight mode are all on one tablet screen.
What data do I get?
4K inspection video and a 3D point cloud from the same flight. The point cloud opens on a PC, for example in CloudCompare, to measure distance, volume and structural change.
What happens if it hits a wall?
The carbon-fibre cage takes the contact. The drone can touch walls, pipes or racks without falling and keep flying.
Where is service and support?
In Indonesia. Repairs, spare parts and software customisation are handled locally, typically in days rather than weeks.
