When an allision, clearance dispute, or lock incident occurs, the communication timeline can be difficult to reconstruct after the fact.
Towerless passively captures configured Marine VHF activity at locks, bridges, and waterways, creating a searchable record for review.
Clearance activity should be reviewable.
No channel changed.
No movement workflow changed.
Locks, bridges, inland waterways, and vessel operators rely on marine radio for passing arrangements, clearances, lift requests, and safety calls.
These communications often help explain the timeline before an incident.
Towerless records configured Marine VHF activity and creates a searchable timeline for review and operational reporting. Where AIS data is available, vessel context can be linked to the record.
Built to sit beside the operation.
- Listen only.
- Process locally.
- Link context where supported.
- Export the record.
- No workflow change.
Designed to build a local supplementary record without transmitting, interfering, or changing the workflow.
