12 ST | June 2018 in 3D, so precise control of dynam- ic operations is possible; the abili- ty to instantly visualize complex structures; and the ability to gener- ate survey-grade bathymetric data without post-processing. The patented Echoscope range of real-time sonars is more than visual- ization tools, as they enable the cap- ture of hydrographic-quality data in real time from the same sensor. This allows an operator to use the sonar for a multitude of purposes, such as visualization of a valuable asset on the seabed and simultaneous use of data to provide an as-built or as-laid survey. The new Echoscope 4G Surface is available in single-, dual- and triple-frequency models offering unique combinations of frequency at 240, 315 and 630 kHz and open- ing angles of 90° by 44°, 50° by 50° and 24° by 24°. This combination of frequencies and opening angles enables the Echoscope 4G Surface to be deployed in a wide range of operations and tasks. Software Our standard USE software oper- ates with all of our sonar systems. USE offers additional features to enhance operations, including the ability to insert georeferenced mod- els to enhance and visually augment the acoustic sonar data, the ability to operate with and without GNSS position and motion data, and the ability to export raw or binned point-cloud data for processing in third-party hydrographic software. We have further developed our proprietary visualization software to add the ability to track targets for the breakwater construction market and our construction-specific soft- ware CMS. This software enables both the visualization of large con- crete blocks as they are placed in the water and automatic tracking and overlay of a 3D model of the block to assist the operator with ac- curate placement of the block. Our software also records the as-laid x, y, z position and the orientation of each block, building up a 3D model of the constructed breakwater. The versatility of the sonar/hardware combination has been validated by block design consultants. Applications Coda Octopus has successfully demonstrated the Surface during a U.S. Navy training exercise in 2018 as part of a Naval Sea Systems Com- mand (NAVSEA) 3D HUD System. The greatly reduced weight, size and power requirements of the Sur- face are ideally suited for launch on small rapid-response rigid inflatable boats (RIBs) and additional inflat- able craft used in law enforcement, salvage and underwater construc- tion. During the live demonstration, tethered divers were able to hand carry the near-neutrally buoyant Echoscope 4G Surface underwater and use it in two critical opera- tional modes: navigation (first-per- son, real-time 3D navigation and scene awareness) and observation (third-person, real-time 3D scene observation). With the ability to visualize and map data and image moving ob- jects in 3D under the water in low- or zero-visibility conditions, our range of sonars have a large number of market applications across the world. One of our key markets has been subsea construction, such as imaging and survey of dredging and construction sites, ROV-based oil and gas projects for key infrastruc- ture installation and installation of breakwater construction. The ability to "see" what is happening under the water can significantly improve the speed and safety of a project. The new Echoscope 4G Surface has been designed with these types of shallow-water construction proj- ects in mind, offering a cost-effec- tive route to delivery. The new Sur- face system can be used with our proprietary software packages, USE and CMS software, giving the option of deployment on cranes, barges or survey vessels to image and map breakwaters, inshore bridges, piers and complex structures, providing real-time assessment of the accu- racy of asset placement, damage to a structure and the effects of any environmental condition such as scour.
