Emergencies.
Disaster survey and search and rescue. Based on practical cases from Yazhou Bay, Hainan Province.
Two response profiles.
Disaster survey
First-hour aerial survey of the affected area: extent, access routes and structural damage, streamed to the command center.
Search & rescue
Air and surface platforms working the same grid — including rescue surface drones on the water leg.
The Yazhou Bay deployment is our reference case: the mission profiles above are written from it, not from a laboratory scenario.
- Rapid deployment from vehicle or hangar
- Live video and position feed to command
- Rescue surface drone for water incidents
- Coordination with the firefighting helicopter case in Custom
Disaster survey.
The first hour, seen from above.
Extent, access routes and structural damage streamed to the command center while ground crews are still en route. Written from the Yazhou Bay deployment, not a laboratory scenario.
- First-hour aerial survey of the affected area
- Access-route assessment for ground crews
- Live stream and position feed to command
- Deployment from vehicle or hangar
Search and rescue.
Air and surface working the same grid.
Aerial platforms fly the search pattern; rescue surface drones take the water leg. Both report into one grid so a sighting becomes a position every unit shares.
- Coordinated air and surface search grid
- Rescue surface drone for water incidents
- Thermal and low-light payload options
- Shared live positions across all units
