The Coda Underwater Inspection System or UIS is the world's only fully integrated high resolution 3D inspection system, delivering precise and intuitive 3D images in real-time. Designed to inspect large areas with 100% coverage and 98% probability of detection, the UIS builds on the extensive knowledge gained in the development and testing of a Mobile Inspection Package in collaboration with the Center for Ocean Technology,University of South Florida, with funding from United States Office of Naval Research (ONR) and United States Coast Guard (USCG).

At the heart of every UIS is the unique Coda Echoscope real-time 3D sonar incorporating cutting edge phased array technology to simultaneously generate over 16,000 beams, resulting in an instant three dimensional sonar image, where the position of every data point is accurately known. Producing detailed images from a single sonar ping, Echoscope is capable of updating at up to 15 times per second allowing rapid coverage of large areas, up to 20,000 linear feet per hour. Using patented 3D mosaicing techniques, large areas can be inspected very quickly and integrated into an intuitive geo-referenced visualisation of the whole underwater scene in real-time, in the murkiest of waters.

To ensure accurate positioning the UIS is integrated with the Octopus F180 series precision attitude and positioning system. Providing absolute positioning at accuracies of up to 10cm (4"), with heading better than 0.05°, high accuracy is key to ensuring that all data is correctly geo-referenced, enabling real-time mosaicing as well as quick relocation of areas of interest from previous inspections. As part of a small boat package, the UIS includes a ruggedized digital video camera or optional night vision camera to provide a separate and immediately obvious above water reference. For remotely operated vehicle (ROV) installations, the latest laser scaling camera provides an accurate visual cross reference. Depending on the application and platform, the UIS can be combined with a wide range of additional sensors and other sonars to create a fully integrated bespoke package. Centered around the unique and powerful Echoscope 3D sonar, the integrated UIS solution offers significant advantages and superior performance over systems using 2D sonar, sector scan sonar, acoustic lens sonars or underwater video cameras alone.

All UIS data is routed through a specially designed C3 (command, control and communications) interface that also handles power distribution, video digitisation, Ethernet switching, data compression and distribution. Using secure wireless and secure web-broadcasting, UIS data can be viewed and analysed from anywhere in the world. Platform independent and available in a number of standard configurations, the UIS can be rapidly deployed from a surface boat, remotely operated vehicle (ROV),autonomous underwater vehicle (AUV/UUV) ormounted in a fixed position (such as a harbour entrance) to suit the application. UIS flexibility also means the same components can be used on other platforms for different applications such as searching a ship's hull for IEDs or contraband or inspecting the structural integrity of a dam or levee and can be easily operated in navigationally restricted environments.
