System Features


Underwater Detection

StructureScan™ is Navico’s SONAR "imaging" solution using both common high frequency side-scan technology (popular in military, oceanographic, and other research fields) with Lowrance’s own breakthrough DownScan Imaging™which incorporates high resolution images presented in a traditional downward looking image to the operator.

Our ability to overlay and interlace DownScan Imaging™ onto the standard sounder image allowing the user to further interpret screen images with greater accuracy.

StructureScan™ allows you to search a 200m by 200m area in less than an hour, before you put divers into the water



Surface Detection

Broadband Radar™ automatically tunes out interference that may come from other radars operating in the vicinity. The special IR software will remove other radar noise; yet still maintain a perfect radar picture around the boat.

Broadband Radar™ has fewer emissions than a mobile phone, and requires very little power, ideal for all types and size of SAR vessel.

FMCW radar is extremely difficult to detect (LPI); ideal for covert operations. Situational awareness is exceptional with chart overlay.

Amazing target detection and separation makes Broadband Radar™ ideal for close operations

Our fourth generation Broadband radar offers features that no other compact system can offer

Multi Function Displays (MFD) & Integration

Experience zero chart lag time with high power processing of NSE and NSO to zoom, pan and navigate without waiting for screen refresh.

Case Study:


Vessel Deodar III, 18.5m Police Patrol Boat
Location Hauraki Gulf, New Zealand
Operational Area 2,000sq nautical miles
Installed equipment StructureScan™



The Auckland Police Maritime Unit operational area covers nearly 200 islands including Great Barrier, and Waiheke as well as the Firth of Thames and associated harbours and inlets. The unit operates the 14.7m launch Deodar III, three 12 metre Rigid Hull Inflatable Boats (RHIBs) and a 3.8m inflatable dinghy, Red Knight.

User Comments

"The advantage of StructureScan is the ability to see real time what is below us. However we also like the ability to review the data again in the office just in case we missed something."

"We use StructureScan to locate objects then follow up with an underwater camera and finally send divers. StructureScan is an excellent ‘pre-dive’ tool."

"Prior to installing StructureScan a 200m x 200m grid would take 4 divers plus a support vessel a whole day to search. With StructureScan we can complete that task in 30mins – 1 hour giving us a huge time and resource saving."

Case Study:


Vessel German GSG-9 Special Force
Location Germany
Operational Area Classified
Installed equipment SIMRAD NSO, 4G Broadband™ Radar



The GSG 9 is unique amongst special forces, being formed from police ranks rather than the military.

GSG 9 is deployed in cases of hostage taking, kidnapping, terrorism and extortion. The group may also be used to secure locations, neutralize targets, track down fugitives and sometimes conduct sniper operations.

User Comments

"The Broadband Radar and NSO display significantly aids presentation and interpretation by showing the targets in different colours and shades; the better the echo, the more intense the colour. We were immediately convinced of its benefits, especially under high speed in MARPA, and in AIS mode we were able to identify every single target.


"Beside the reliability of the system, the most impressive thing was the radar target resolution. You can see the target clear on the screen until you can literally reach out and touch it – it’s unbelievable, it’s more like a camera than a radar!"

User Comments

"We replaced our Raymarine system with Simrad NSE + 4G and not only have experienced dramatic increase in reliability we have much more user friendly interface for our Search and Rescue operations. The 4G radar has increased our situational awareness and given my crew confidence in navigation in all conditions."

Vessel Unmanned Suface Vessel (USV)
Location Persian Gulf
Installed equipment SIMRAD NSS, 4G Broadband™ Radar, AP28, BSM1, GoFree



The primary missions for Eclipse Class vessels are surveillance and non-lethal deterrence for small craft. They can be operated remotely via encrypted RF from shore, or world-wide via secure satellite links. These are also true robots, which can be pre¬programmed to perform fully-autonomous missions. Options include inertial navigation and Faraday-caged hulls for EMP protection. They are fast, robust, and modular ... and adaptable to a very wide variety of applications.

These Eclipse Class vessels will be introduced at IDEX 2013 (The International Defence Exhibition and Conference), 17 - 21 February 2013 in the Abu Dhabi National Exhibition Center.
