Navigator

Bringing diver navigation to new heights.

The Navigator is a second generation Sonar Imaging and Navigation System, designed by Shark Marine primarily for MCM and SAR use.

A one man Navigation and Sonar Reconnaissance unit.

The Navigator is in use by many of the world's Navies, and has become a trusted piece of their standard kit and reshaped many of their SOPs. The modularity of the system and numerous advanced sensors available allow the Navigator to become a force multiplier, enabling smaller groups to cover more ground in less time.

Many Police forces and Fire Departments are also using the Navigator in homeland security / search and recovery roles as well as scientific organizations, and commercial dive companies.

The Navigator is the most modular system of its kind, enabling it to be quickly configured for any application. The modularity of the system also means that it will never become obsolete, as technology advances in certain areas these components can be replaced, rather then needing to replace the entire system. Shark Marine’s DiveLog software controls all operations of the navigator and its accessories, operators need only learn one software to master all their equipment.

Accessories:

Surface GPS:

The Surface GPS can be used when the Navigator is functioning on the surface. It also works well as a rapidly deployed system where it would provide the initial position ﬁx for the DNS.

Floating GPS:

The Floating GPS provides positioning in shallow waters. This system can also be periodically deployed to the surface to remove any time accumulated error when using the DNS for long range covert operations.

881A Azimuth Drive:
Rotary Actuator Drive

The Model 881A Azimuth Drive is a rugged and powerful rotary actuator drive that can be coupled to an Model 881A Profiling Sonar. The two axes of rotation in this combined unit provide the capability to obtain accurate, high resolution range information in any direction. In standard applications, profiles may be made in any direction by simply commanding the Azimuth Drive to rotate the attached profiling sonar anywhere in a circle. The profiling sonar can then perform a cross-sectional scan before being rotated to a new azimuth angle. The Azimuth Drive uses the same RS-485 serial communications line and command structure as the profiling head. A single, simple to use PC compatible computer program operates both, and full communications protocol specifications are provided for designing customized software.

Surface GPS:
The Surface GPS can be used when the Navigator is functioning on the surface. It also works well as a rapidly deployed system where it would provide the initial position ﬁx for the DNS.
Floating GPS:
The Floating GPS provides positioning in shallow waters. This system can also be periodically deployed to the surface to remove any time accumulated error when using the DNS for long range covert operations.
Pole GPS:
The Navigator Pole GPS was designed for use with the Rapid Beach Proﬁling system, or other applications where the operator will be swimming on the surface.
Doppler Navigation System [DNS]:
The Doppler Navigation System tracks the divers movement over the sea ﬂoor. As a result it does not require a satellite ﬁx or base stations once its initial position has been set. The DNS is an ideal set up for covert rapid deployments (when paired with the surface GPS) or to ﬁll in any gaps caused by acoustic shadows when using the LBL system.
Long Base Line [LBL Positioning System]:
Shark Marines LBL system provides high precision underwater navigation without the need for a ﬂoating GPS or tethers to the surface. This system can use 2 or 3 base stations which can be rapidly deployed from any small craft or by a diver. The LBL is the system of choice for any long duration underwater searches.
Motion Reference Unit:
The Extended MRU option provides the Navigator or Dive Tablet with a more accurate compass and full 360 degree pitch and roll orientation data. Highly recommended for use on the Navigator with forward-looking sonars and the Doppler Navigation System for more accurate positioning.
Forward Looking Sonars:
P-450 Series – Long Range:

The P-450 series forward-looking sonar is the best solution to detect, monitor, and track objects and/or targets at distances up to 300 meters (984′). The P450 is available with a 45°, 90°, or 130° field of view.

Frequency: 450 kHz

Range Max: 300 m (904′)

P-900 Series – Mid Range:

The P900 series forward-looking sonar is the ideal sonar for underwater detection and identification operations up to 100 meters (328′). The P900 series is also available with a 45°, 90°, or 130° field of view.

Frequency: 900 kHz

Range Max: 100 m (328′)

P-900-2250 Mid – Short Range:

The P900-2250 forward-looking sonar combines a medium range 900-45 navigation and inspection sonar with the identification capabilities of a higher frequency 2.25 MHz sonar head.

Frequency: Selectable 900 kHz 2.2MHz

Range Max: 100 m(328′) 900kHz 12 m (39′) 2.25MHz

Sound Metrics Aris:

The Sound Metrics Aris sonar is a dual frequency unit that provides extremely high resolution imagery at short range, well suited for detailed inspections and target identification.

Frequency: Selectable 1800kHz, 3000kHz

Range Max: 15 m (50′) 1800kHz and 5 m (16′) 3000kHz

Tritech Gemini:

At 720kHz the tritech Gemini is well suited for medium to long range searches (120 m (394′)). The wide even image of the Gemini allows this sonar to make very clean mosaicks. Its small size also makes it a perfect fit for Shark Marine’s Navigator DT2 system.

Frequency: 720 kHz

Range Max: 120 m (394′)
Pro-Mag-Magnetometer:
The PRO-MAG is a high sensitivity Overhauser Magnetometer that can be equipped on the Navigator to locate objects with ferrous content.
725K Metal Detector:
The Ebinger 725K is a ﬁeld proven, valuable tool for underwater ordnance detection. When integrated with the NAVIGATOR its abilities are further enhanced with the addition of a visual data display and the navigational features of the system.
Radiation Detector:
The Shark Marine radiation detector is a plug and play unit designed to detect gamma radiation underwater.
Bathymatric Sonars:
Sonar Altimeter:

The Sonar Altimeter measures the distance to the sea floor. The Sonar Altimeter can also be used to gather bathymetric / beach proﬁle data.

Multi-Beam Profiler:

The Multi-Beam Proﬁler can be used to gather bathymetric data. The Multi-Beam covers a much larger swath than the Sonar Altimeter.

Transom Mounted Altimeter Sonar:

The Transom Mounted Altimeter Sonar is used for the Rapid Beach Profiling System (RBPS). It was designed to quickly mount to vessels of opportunity for collecting bathymetric and beach profile data.
Underwater Head-Mounted Display (UHMD):
Designed for use in zero visibility situations, or for operations where a low light signature is required, the Underwater Head Mounted Display (UHMD) brings the NAVIGATORS display right to the divers mask. The UHMD is available as a monocular or binocular version. Mounts are also available for different masks or helmets.
NavNam:
The NavNam is a plug-and-play digital camera that mounts onto the Navigator. It can capture still images up to 1920 x 1080 and video up to 1280 x 720, which are geo-referenced (if a position is available), and digitally stored in the DiveLog project.
Sub-NET Communications System:
Sub-NET is an underwater communication system that allows multiple Navigators to communicate with one another or to surface vessels or other assets. Sub-NET also allows connected Navigators / other assets to share their locations with one another, as well as send target information and waypoints.
NavCam:
The Navigator system can be mounted to many different Diver Propulsion Vehicles. Contact us with your specific needs in this area.
DPV Mounts:
The NavNam is a plug-and-play digital camera that mounts onto the Navigator. It can capture still images up to 1920 x 1080 and video up to 1280 x 720, which are geo-referenced (if a position is available), and digitally stored in the DiveLog project.
Nav Light:
The Nav Light provides even lighting to aid in capturing video or still images of targets using the NavCam. Can also be used simply for the diver’s vision.

Brightness: 1300 Lumens.
Pole Mounted Sonar System:
Designed for boat operations, the Pole Mounted Sonar System allows the operator to search large areas with geo-referenced forward looking sonar, and collect bathymetric / beach profile information.
