Drones for Critical Infrastructure

Drone Inspections of Critical Infrastructure — Power Transmission and Rail

Safe diagnostics of HV transmission lines, substations, catenary systems and rail track beds — without halting train traffic or disconnecting voltage. Documentation ready for maintenance records and tender procedures.

Growing capability: we are preparing formally and with equipment to work with critical infrastructure operators under tender procedures. Corridor LiDAR scanning will launch once our fleet adds a DJI Matrice 400 platform.

What does a critical infrastructure drone inspection cover?

⚡

Transmission line inspection (PSE)

Detailed photos of conductors, insulators, hardware and support structures of 110/220/400 kV high-voltage lines. We detect corrosion, mechanical damage, insulation loss and excessive sag without approaching live conductors.

🚆

Catenary and track-bed inspection (PKP PLK)

Inspection of catenary systems, traction poles, insulators and track-bed condition. We detect contact-wire damage, corrosion of support structures and irregularities around the track — without closing rail traffic.

🌉

Engineering structure inspection

Technical condition documentation of rail viaducts, bridges over rail lines and embankments. Photogrammetry and 3D models support diagnostics without erecting scaffolding over live tracks.

🌡️

Substation and traction substation thermography

Thermal imaging of transformers, switchgear and traction substations under load. We identify overheating connections and overloaded elements before they fail.

🌲

Corridor and vegetation monitoring

Checking tree and vegetation encroachment into the line's protection corridor. High-resolution photos and tree-height measurement support protective clearing planning.

📊

Technical report matching operator requirements

Complete PDF/GIS report with geolocated faults, priority classification and photo documentation — in a format ready for handover to maintenance crews and tender documentation.

Who benefits from critical infrastructure drone inspections?

Linear infrastructure — transmission lines, catenary systems, track beds — needs cyclical inspections across tens or hundreds of kilometres while keeping traffic and power supply running. Drones deliver that inspection without halting the infrastructure's operation, cutting inspection time from days to hours.

Transmission and distribution system operators (e.g. PSE) — regular HV line inspections without voltage disconnection
Rail infrastructure managers (e.g. PKP PLK) and carriers — catenary and track-bed inspection without halting traffic
Contractors and subcontractors on HV line and rail investment projects — progress and handover documentation
Maintenance and service companies — fast diagnostics of faults flagged by network monitoring systems
Insurers and expert witnesses — independent technical-condition documentation of linear infrastructure before and after events (storms, floods)

How does a critical infrastructure drone inspection work?

1

Site analysis and formal approvals

We define the route scope, check airspace zones, obtain the approvals needed for flights near specially protected infrastructure, and coordinate the schedule with the line or track operator.

2

Inspection flight

The drone with thermal and optical cameras (112× zoom) flies the route at a safe distance from conductors and catenary systems. Every photo is geotagged with RTK accuracy ±2 cm.

3

Data analysis and fault classification

We process the material, classify anomalies by priority (urgent/planned) and identify elements requiring immediate intervention.

4

Report and documentation handover

We deliver a PDF/GIS report with a fault map, GPS coordinates and recommendations — ready for inclusion in maintenance or tender documentation.

Frequently asked questions — critical infrastructure

Does a drone inspection require halting train traffic or shutting down the power line?
No — that's the key advantage of drone inspection. The drone keeps a safe distance from live tracks and conductors, so the survey happens without halting rail traffic or interrupting power supply. Flights in the immediate vicinity of critical infrastructure require prior coordination with the facility's operator.
What approvals are needed to fly over rail and energy infrastructure?
Flights near rail and energy infrastructure require airspace zone analysis, the site operator's consent and, in some cases, the relevant aviation-authority permit for operations near people and infrastructure. We prepare operational documentation before every flight.
Do you offer corridor LiDAR scanning?
We currently carry out visual and thermal inspections (RGB + FLIR) with photogrammetry for 3D documentation. Corridor LiDAR scanning — measuring vegetation clearance from conductors at centimetre accuracy — will launch once our fleet adds a dedicated LiDAR-equipped platform.
Do you have experience working for PKP PLK or PSE?
We provide drone inspection services for operators and contractors active in power transmission and rail infrastructure. We are formally and technically prepared to take part in these organizations' tender procedures — current UAVO pilot certificates, business liability insurance, and readiness to sign an NDA. Reference details are shared at the RFQ stage.
How long does inspecting a 10 km line or track section take?
Roughly one working day per 5–10 km of route, depending on the density of poles and checkpoints and site access. For longer routes we deploy multiple teams in parallel.
How much does a critical infrastructure drone inspection cost?
Pricing depends on route length, the density of inspected assets (poles, substations, engineering structures) and the required report format. For tender-driven projects we prepare an individual quote based on the client's specification.
What documents does the client receive after the inspection?
A PDF report with fault classification, full-resolution RGB and thermal photos, a GIS layer with anomaly locations and — on request — source data for the client's own GIS/CMMS systems.
