Capability profile
Wire-guided laser/camera measurement of vertical gate and stoplog surfaces above and below water, producing geometric models and profiles.
Wire-guided laser/camera measurement of vertical gate and stoplog surfaces above and below water, producing geometric models and profiles.
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Current dedicated service; Hydro-Québec confirms joint production/commercialization of its developed technology with ASI’s division. Unnamed BC vendor case is attributed; no universal independent precision or asset acceptance is established.
Specify visibility, flow, vertical extent/platform clearance, geometry, deliverables and acceptance tolerance. Supplier states currents below 5 cm/s ideal, with 5–10 cm/s considered; confirm conditions per assignment.
A technology readiness level is not established by the reviewed public sources.
No reviewed Mission area or released Defence need connection is currently published.
These records support this capability and its published Mission area and Defence need connections. A source count is not a count of independent confirmations.
