Bridge data gaps in challenging environments

Comprehensive data is key to supporting operational decisions. Yet many hazardous environments are beyond the reach of existing data capture technologies.

Flyability's Surveying Payload turns the Elios 3 into a flying mobile scanner that can fit through openings as small as 50x50cm, and create high resolution scans beyond line of sight, allowing industry professionals to provide rapid insights that are not accessible with traditional tools or other UAV technologies.


Survey-grade accuracy

The high resolution Ouster OS0-128 Rev 7 LiDAR sensor in combination with the world's leading FARO Connect SLAM algorithm create incredibly accurate 3D maps and digital twins of the most inaccessible spaces with centimeter precision - for accurate measurements and greater insights.

New mapping capabilities

Powered by the latest Ouster REV 7’s supercharged L3 chip, the Elios 3 has the ability to capture points further apart and to detect more usable visual features. This maximizes the chance for the SLAM algorithm to converge when computing 3D models of cylindrical and symmetrical environments such as collectors, chimneys, culverts, or underground galleries.

Uplifted mapping efficiency

For all applications where centimeter accuracy matters, mobile scanning is far more effective than traditional methods such as total stations or terrestrial scanners. With a range of 100 meters, a point density of 1,310,720 pts/sec and a capacity to cover a 300 meters tunnel (close loop) in a single flight, the Elios 3 Surveying Payload can turn days of mapping into a 10-minute job.

Scanning beyond safe access

With its small form factor, the Elios 3 and the Surveying Payload can fit through openings as small as 50x50cm. It has a fixed cage that physically protects the hardware and a patented combination of flight controller and motor design that allows the drone to recover flight stability after a collision. This enables the drone to navigate through the most complex environments to capture high resolution scans where no other technology can.

Create clean, georeferenced point
clouds automatically

The Elios 3 Surveying Payload is bundled with FARO Connect, a powerful software solution to process and manage the Elios 3’s LiDAR data. Powered by the world’s leading SLAM algorithm, FARO Connect converts data from the Elios 3 into highly accurate point clouds and provides a range of SLAM presets, optimized for the most common data capture scenarios of the Elios 3. Features include:

Data alignment

Combine multiple point clouds to produce one single scan using reflective targets.


Automatically georeference point clouds using reflective targets.

Point cloud filtering

Refine Elios 3 3D models with various filters including outlier removal, surface noise reduction, and removal of unwanted points.

Easy export

Output the processed point cloud data to your required file type: LAZ, LAS, PLY, TXT, and E57.


A one-stop solution

To get you started, the Surveying Payload comes as a comprehensive package, which includes:
