Marine Tracer USV Successfully Completes Testing for Underwater Search and Recovery (SAR)

By Published On: April 26, 2024Categories: News

In a series of controlled field tests, Marine Thinking has successfully concluded its Marine Tracer™ uncrewed surface vessel (USV) can be utilized as a support tool for underwater search and recovery missions.

Combining side scan sonar with autopilot navigation, Marine Tracer™ USV scans for drowned persons while automatically following a pre-set search pattern based on GPS coordinates. All sonar footage is displayed in real-time, allowing trained search and rescue (SAR) personnel to identify and geotag locations of interest for dive teams to investigate further.

In terms of efficiency, Marine Tracer™ USV was able to consistently scan 1,200 m2 in 10 minutes. The dual frequency sonar sensor equipped on the USV can support up to 23 m (@ 1075-1150 kHz) and 146 m (@ 455 kHz), respectively.

Testing was performed at various waterbody locations throughout Halifax Regional Municipality and the Survival Systems Training facility in Dartmouth, Nova Scotia. Water rescue training manikins were used to simulate human bodies for imaging sonar testing.
