Drone Internal Confined Space Inspections
Making dangerously inaccessible assets accessible safely!
Very simply, DTA's internal confined space inspection drones enable inspection of assets that are otherwise almost completely.
Avoidance of working at height and in dangerous spaces transforms the work environment with vastly improved HSE compliance.

DTA's Internal Confined Space Inspection Drones
We use the Elios 2, Elios 3, customised DJI Mavic's, and our own custom drones for internal inspections depending on the project complexity, data requirements and budget.
Elios 3
The Elios 3 is the state-of-art in internal inspections. A versatile and capable internal inspection drone designed for various inspection and mapping tasks.
Here is a summary of Elios 3 capabilities:
-
Real-time LiDAR Mapping:
Provides centimetre-accurate indoor positioning and mapping, generating real-time 3D models and high-resolution visuals. -
Robust Inspection Capabilities: Equipped with a 4K camera, thermal imaging, and 3D point cloud capabilities for detailed inspections.
-
Modular Payload Bay: Features dual ports for LiDAR and auxiliary sensors, ensuring future upgradeability.
-
Advanced Surveying Payload: Uses Ouster REV7 LiDAR and FARO Connect for survey-grade point clouds, ideal for mapping tunnels and inaccessible interiors.
-
Smart Return-to-Home: Ensures safe navigation back if signal is lost or battery is low, using live LiDAR-sensing.
-
SLAM-Based Stabilization: Offers rock-solid flight stability using visual-inertial odometry and LiDAR, even in turbulent or dark conditions.
