Smart Tether Search and Recovery Technology Using ROVs and SONAR

KCF Technologies has developed a Smart Tether system for Kongsberg-Mesotech sonar units which integrates Smart Tether positioning functionality with the Kongsberg Mesotech MS1000 software.

This system provides a powerful package for quickly performing a comprehensive search of an area and easily documenting the results. KCF has successfully performed lake-bottom scans using this combined system.


With this new capability, it's also quite easy to do ROV-supported scan operations. KCF's test was performed using 2 independently-operating Smart Tether systems, one on the Kongsberg sonar and one on a VideoRay Pro4 ROV. It is very easy to find targets using the sonar and then navigate to them with the ROV, all in real time using the data from the Smart Tethers to coordinate between the two technologies. The ROV can be identified and tracked on the sonar screen as well, providing the ROV pilot additional feedback.

This technology combination can prove very powerful in quickly locating targets and piloting the ROV to them for identification and inspection, allowing an area to be quickly swept without needing to put divers in the water to investigate every target.

Combined with the quick setup time of the Smart Tether, this system allows a very large area to be completely searched and accurately documented very quickly with minimal response time, providing excellent value for first responders and other search and recovery teams.

Nion: Next-level time-of-flight

The new Nion 3D camera advances Time-of-Flight (ToF) technology with exceptional resolution, speed, and industrial robustness. Designed for demanding applications such as logistics, warehousing, industrial automation, and robotics, Nion delivers high-resolution depth data with real-time performance for faster, safer, and more flexible operations. At its core is the 1.2-megapixel Time-of-Flight sensor AF0130 from onsemi's Hyperlux ID family, offering up to four times the resolution of conventional VGA-based ToF cameras and significantly higher data density. Active 940-nm laser illumination ensures accurate and stable measurements in low-light conditions, artificial lighting, and even direct sunlight. With an IP67-rated housing, Nion is built for reliable operation in dusty, wet, and thermally challenging industrial environments. A user-friendly API with IDS peak support and compliance with the GigE Vision standard enable fast integration and flexible deployment in high-resolution 3D applications. The Nion 3D camera is now available from IDS Imaging Development Systems.
