No GNSS dependency
Operate in indoor and underground assets where satellite positioning is unavailable.
Confined-space inspection
Collect evidence where access is confined and hazardous.
COAX is being developed for close-range drone inspection in enclosed assets where GNSS is unavailable and sending a person inside requires careful planning.

Remote assessment before manual entry
Confined spaces often combine restricted access, poor visibility, uncertain geometry and operational hazards. A compact inspection drone can provide an initial view of conditions and collect evidence for a better-informed entry or maintenance plan.
Confined-space inspection
Designed for enclosed environments
Close-range observation
Approach walls, pipes, joints and structural elements that need detailed visual assessment.
Shared inspection record
Keep findings, source material and reporting in one RevSight workflow.
Use cases
Confined spaces suited to remote inspection
The exact method depends on geometry, hazards, access and the evidence required.
- Technical shafts and service ducts
- Tanks and enclosed process assets
- Underground passages and culverts
- Incident scenes with uncertain access conditions
COAX + RevSight
Plan around risk and required evidence
The flight is one part of a broader inspection method.
Assess
Review geometry, access points, hazards, communications and inspection objectives.
Inspect
Capture close-range data in the agreed zone without making manual entry the first step.
Decide
Review findings and determine whether maintenance, further testing or controlled entry is needed.
FAQ
Confined-space drone inspection FAQ
Why use a drone before entering a confined space?
A remote first look can improve knowledge of geometry and visible conditions before teams decide on entry, equipment and further testing.
Can COAX inspect an asset with no satellite signal?
Yes. COAX is designed specifically for enclosed and underground environments without GNSS/GPS.
Is visible imagery enough for every assessment?
No. Visual data can support decisions, but some defects require specialist sensors, measurements or direct testing under the applicable inspection procedure.
