Iver4 for USN

L3Harris Technologies will provide an unmanned undersea vehicle for expeditionary undersea missions for U.S. military forces by the U.S. Navy and the Defense Innovation Unit (DIU). DIU, which accelerates commercial technology to solve national security solu- tions, awarded an Other Transaction Agreement (OTA) to L3Harris for the U.S. Navy’s Next

SubSLAM Live: 3D Streaming Tech an Iver4 - 900 PW UUV and two ? eld swappa-

Rovco launched “SubSLAM Live” a 3D Streaming technology ble modular payload sections, including real ap- which it says will allow a video live stream 3D underwater point- erture and synthetic aperture sonars. Additional clouds to any device in the world. According to the company, the ste- sensors, swappable battery chemistries, and data reo camera technology system sends images and 3D models of assets solutions are included with the prototype system from the seabed to a computer browser in any location globally. This to provide U.S. military forces with a highly offers customers instantaneous access to information as an inspec- capable UUV that can detect, classify, localize, tion or construction activity is taking place. Rovco put the tech on and identify targets on the ocean ? oor and in trial earlier in the year with an unnamed oil and gas super major at a the water column in support of Expeditionary renewable wind farm, and more recently in 0.5m of visibility at an Mine Countermeasures (ExMCM), Explosive ex-naval dockyard owned by Offshore Renewable Energy Catapult.

Engineers were using Rovco’s stereo camera system to capture high- de? nition video, which allowed them to use the SLAM (Simulta- neous Localization and Mapping) system to build 3D point cloud models while staff back in their of? ce 300 miles away directed the
