Hard-to-reach areas of buildings, technical installations and infrastructure often require considerable effort to inspect using conventional methods. Scaffolding, aerial work platforms or other access systems are not necessary for every initial assessment. A drone inspection provides an efficient way to access, capture and document areas that are difficult to reach or cannot be adequately viewed from the ground.
UXT Systems plans and conducts drone inspections for industrial facilities, infrastructure and technical installations. The UAV platform is selected and configured according to the specific task and the conditions on site. We consider the complete system, including the aircraft, camera, sensors, navigation and data transmission.
Applications range from visual documentation using high-resolution cameras to LiDAR-based acquisition of spatial structures. Inspections inside industrial facilities, halls, tunnels, shafts and other environments without reliable GPS or GNSS reception can also be carried out using appropriately configured systems.
Drone Inspections for Industry and Infrastructure
Drones are particularly suitable for inspections where areas are difficult to access, difficult to observe or would otherwise require additional equipment or personnel. Depending on the task, individual components can be examined from different perspectives, larger structures can be documented and additional sensor data can be collected.
Typical applications include:
Industrial facilities and production sites
Tunnels and shafts
Bridges, bridge undersides and structural components
Industrial halls and warehouses
Energy and utility infrastructure
Wind turbines
Roofs and façades
Channels and infrastructure structures
Construction sites and buildings
Technical installations and hard-to-reach machinery
The UAV platform and sensor configuration depend on the inspection objective. A visual inspection of a building façade requires a different system configuration than the inspection of a tunnel or a flight inside a complex industrial facility.
Drone Inspections in Hard-to-Reach Areas
One of the main advantages of drone inspections is the ability to capture areas that are difficult to access without immediately requiring personnel to enter them. The drone can record structures, surfaces and technical installations from different perspectives while transmitting the required image and sensor data to the operator.
This makes it possible to perform an initial assessment before further measures are planned. Particularly for large structures, elevated areas or confined environments, the use of a UAV can reduce the effort required to collect relevant information.
The captured images, video and sensor data can subsequently be documented and used for further technical investigation or for planning maintenance and repair activities.
Indoor Drone Inspections in GPS-Denied Environments
Reliable GPS or GNSS reception is often unavailable inside buildings, industrial halls, tunnels, shafts and enclosed facilities. Confined spaces, obstacles and the absence of a direct line of sight also place additional requirements on the UAV platform and its navigation system.
For these applications, UAV systems can be equipped with alternative technologies for positioning and environmental perception. These may include LiDAR, optical sensors and additional navigation sensors.
During flight, these sensors continuously collect information about the surrounding environment. Depending on the system configuration, the data can be used for navigation, positioning and spatial data acquisition.
LiDAR-Based Navigation
LiDAR sensors measure distances to objects and structures in the surrounding environment. This information can be used both for spatial data acquisition and as part of a GPS-independent navigation solution.
Combined with optical and additional navigation sensors, UAV systems can be configured for environments where satellite-based positioning is unavailable or unreliable. The specific configuration depends on the size, geometry and technical conditions of the operating environment.
Fiber-Optic Data Transmission
For specific operating conditions, fiber-optic data connections can also be integrated. In this configuration, data between the unmanned system and the ground station is transmitted via an optical fiber connection.
This approach can be suitable for environments where conventional radio communication is limited by structural conditions or where a wired data connection is required for the application.
Whether a fiber-optic system is suitable for a particular inspection depends on factors such as flight path, operating environment, required freedom of movement and data transmission requirements.
Cameras and Sensors for Drone Inspections
The sensor configuration is determined by the information that needs to be collected during the inspection. A high-resolution camera may be sufficient for a visual assessment, while spatial data acquisition, navigation or specialised applications may require additional sensors.
Depending on the project, the UAV system can be equipped with:
High-resolution cameras for visual inspections
LiDAR systems for distance measurement and environmental mapping
Optical sensors for positioning and navigation
Sensors for spatial data acquisition and mapping
Distance and altitude sensors
Additional cameras for specific viewing angles
Project-specific sensors and payloads
Visual Inspection and Documentation
For many drone inspections, visual data acquisition is the primary objective. High-resolution cameras provide detailed images of components, surfaces and structures. Specific areas can be approached during the flight and documented from different perspectives.
In addition to individual images, larger areas can be recorded continuously using video. The resulting material can then be used for documentation, comparison and further assessment by the relevant technical specialists.
3D Data Acquisition with LiDAR and Camera Systems
In addition to conventional image and video capture, drones can be used for spatial data acquisition. With suitable LiDAR and camera systems, indoor environments, tunnels, technical installations and other complex structures can be captured digitally.
Depending on the sensors, flight method and project requirements, the collected data can be used to create spatial datasets for existing-condition surveys, mapping, documentation or further technical analysis.
The requirements for spatial data acquisition are defined before the operation. Relevant factors include the required accuracy, the size of the area, environmental conditions and the intended use of the collected data.
Custom UAV Systems for Inspection Tasks
Not every inspection can be performed with the same drone. Operating inside a narrow shaft places very different requirements on platform size, navigation and sensors than inspecting a large industrial facility or an outdoor structure.
UXT Systems therefore selects the UAV platform according to the specific task and adapts the system where necessary. In addition to dimensions and flight time, payload capacity, sensors, navigation and communication are important factors in the system configuration.
Depending on the project, system adaptations may include:
Integration of additional cameras and sensors
Integration of LiDAR systems
GPS-independent navigation solutions
Adaptation of telemetry and data transmission
Integration of project-specific payloads
Design of custom mounts and components
Adaptation of the UAV platform to specific operating conditions
Planning and Execution of Drone Inspections
Every project begins with the technical requirements. Which areas need to be inspected? What data is required? What are the spatial conditions at the site, and what requirements apply to navigation, sensors and data transmission?
Based on these requirements, the UAV platform, sensor configuration and navigation solution are selected. For conventional inspection tasks, an existing system may be suitable. More demanding applications may require additional sensors, modified communication systems or a specifically configured UAV platform.
This approach enables both conventional outdoor drone inspections and more demanding indoor operations within industrial facilities, halls, tunnels and other GPS-denied environments.
Drone Inspections Configured for the Technical Task
For UXT Systems, a drone inspection is not defined by the aircraft alone. The key consideration is which information needs to be collected reliably under the specific operating conditions.
We therefore combine UAV platforms, cameras, LiDAR, sensors, navigation and data transmission according to the requirements of each project. Applications range from visual documentation of hard-to-reach areas to spatial data acquisition in complex GPS-denied environments.
UXT Systems supports companies with the technical planning and execution of individual drone inspections for industrial facilities, infrastructure and hard-to-reach areas.
