The NAVIGATOR was designed to give a diver “eyes” in waters too turbid to see; for navigation through the dark without lights; for locating distant objects or targets; to record identifying details about the targets; for marking their location and mapping the route to easily relocate them. It may be equipped with numerous application specific sensors. The systems DIVELOG software records the data collected from all of these sensors and geo-references it to the position of the system at the time. At the end of an operation, DIVELOG’s Report Generator can then be used to compile an interactive HTML report of all the recorded activities and their location.

The NAVIGATOR is a complete Windows 7© based, underwater computer. Its modular design allows it to be easily configured for mission specific operations.
Standard computer interfaces accessed through durable waterproof connections allow the simple addition of an ever increasing array of underwater sensors and detection devices. The external connection of these accessories allow them to be easily added and removed in the field without jeopardizing the integrity of the systems internal electronics.
The Navigator is modular by design, allowing flexibility, versatility, and rapid reconfiguration for specific operations. This modularity brings adaptability to changing equipment and requirements and allows new accessories and options to be quickly added. As new technology in sonar or other systems becomes available the systems easily adapt to these to ensure sustainability.
Various positioning systems are available depending on the operation and the degree of accuracy required. A floating GPS is the easiest for shallow water operations. The GPS may be fixed directly to the Navigator for operations with the DNS system or LBL. The Long Baseline (LBL) system has the best accuracy and is recommended for operations such as detailed surveys on a tight grid. The Doppler Navigation System (DNS) system provides accurate position data as a self-contained system with nothing visible from the surface. The Navigator automatically selects the best solution if more than that one system is used at the same time. Therefore if the LBL system were to lose communication in challenging acoustic conditions or in acoustic shadow zones such as those encountered searching ships hulls, the DNS will take over providing uninterrupted position data.
Other readily available accessories include:
Multiple Sonar Heads
Mask Mounted Display
Helmet Mounted Display
HD Video/Still Camera
Long Baseline Navigation

Diver Position Monitor
Comms with base station
Diver Delivery System
Shark Marine’s Divelog software was created to integrate data collected from an array of sensors, real-time, with navigation and positioning information. Divelog’s navigation features allow targets to be entered for reacquisition; for search patterns to be generated and followed; for targets to be recorded real-time by an operator and for recording the actual movements of the diver. Divelog records all of the data collected from a mission into a project folder and correlates all of the information collected with regards to a suspected target, to that targets ID. This information which may include video images, sonar scans, magnetic signatures and more, depending on the attached sensors, can then be easily sorted into a viewable interactive report at the end of the mission.
DiveLog consists of the Navigation Display, plus a number of add-on modules called Active Screens. The Active Screens give DiveLog the ability to expand to use any number of peripherals or functions. The Active Screens are toggled between the Primary and Secondary positions. The secondary screens remain active while parked in the top right corner of the display.
Mapping and Target Marking
Divelog allows maps to be imported for use with an individual mission. The style of map may be selected from a number of available formats including:
S57-ENC, S63-ENC, BSB, Admiralty Raster Charts, ESRI Shapefiles, GeoTiffs, DXF files, Google Earth KML and KMZ and Shark Marines native format “Shark Map”.
Generate Search Grids
The maps may be used to provide a background reference for travel and displaying the diver’s recorded route. They may also be used to help generate routes or “search grids” for the diver to follow. Actual travel over these programmed paths is recorded and targets detected along the way may be marked.
Target locations may also be entered before a dive and used as destination markers for the navigation systems. The subsequent path to each target is also recorded.
Share Target Location
Recorded targets are shared throughout the Divelog software, wherever positions can be indicated such as in a sonar scan. Moving the cursor over the target will show the actual recorded position and other relevant data collected.
Sonar Coverage Mapping
Coverage mapping is one of many features unique to Divelog. The software will calculate the angle and range of the sonar in use, to create a map of the total area covered by the beam. This can then be used to ensure that no area has been missed or overlooked when searching for a specific target.
