Sonar Interface Unit

The Octopus 160 sonar interface unit's design and is compact, rugged and weather-proof. Compatible with EdgeTech's work-horse 272TD dual-frequency side-scan sonar, it is simple to operate and is suitable for small boat use in many types of underwater survey. Housed in a rugged custom Pelicase, the 160 is highly portable and it can be operated with the lid closed allowing uninterrupted operation in harsh environments.   Another popular feature is the new user interface for all controls and once configured for a specific towfish, this needs no further adjustment. With direct connection to standard EdgeTech 272TD tow cables and full... (read more)

‘Killer’ AUV Sonar System

In January 2001, C&C Technologies (C&C), a company based in Lafayette (Louisiana, USA), introduced the first commercially successful autonomous underwater vehicle (AUV) to the offshore industry. The AUV’s survey sensor suite, which included an EdgeTech side-scan sonar and sub-bottom profiler, performed well in the Gulf of Mexico and Brazilian offshore environments. However, West Africa proved more challenging – particularly for the sub-bottom profiler. C&C soon began searching for alternative technologies to provide better sub-bottom profiler penetration and higher resolution side-scan sonar imaging.Jim Chance, C&C Technologies (USA) Art Kleiner, EdgeTech (USA)<P> Narrator: Fast forward to the early autumn of 2004… C&C...

Obstacle Avoidance Sonar

Sonardyne International, UK, has announced the launch of its new Navigation and Obstacle Avoidance Sonar, NOAS, at NAVDEX 2013 in Abu Dhabi. Designed for use on submersible vehicles, NOAS enables faster, safer and more efficient navigation by detecting and classifying potentially hazardous underwater obstacles in its path. Unveiled on the first day of the exhibition, NOAS provides a unique combination of very long range 2D navigation performance, 3D object detection and class leading intruder detection in a single compact sonar. In 2D mode NOAS provides the crucial long range navigation information enabling underwater vessels to steer a safe course. When... (read more)

SeaSprite Sonar for VideoRay

VideoRay LLC announced that Tritech International has produced the SeaSprite sonar as a new accessory for the VideoRay ROV. The SeaSprite weighs just 5 ounces in water and is ideal for small ROVs and AUVs in military and covert uses. By equipping the VideoRay with the SeaSprite sonar, obstacles can be located, identified, and measured in low visibility environments. The SeaSprite simply plugs into any VideoRay Pro II and features an extremely fast scan rate to match VideoRay's high maneuverability. No calibration is needed. When plugged into a Pro II, the SeaSprite can be used in low visibility conditions and... (read more)

Side-scan Sonar Demonstrations

During Ocean Business 2009, L-3 Klein will be running live demonstrations of the L-3 Klein System 5000 V-2. The demonstrations will be conducted on-board the Bill Conway on Tuesday, 31st March at 1530, Wednesday, 1st April at 1400 and Thursday, 2nd April at 1030.     The L-3 Klein System 5000 V2, with the added swath bathymetric capability, employs advanced Interferometric signal processing to produce simultaneous estimates of the seabed topography out to the full swath extent of the sonar, typically 10 to 12 times the overall altitude of the tow fish. This added seabed topographic measurement is post processed... (read more)

Didson Next-generation Sonar

Sound Metrics Corp, UK, the manufacturer of the high-resolution Didson multi-beam sonar, has developed its next-generation sonar, ARIS (Adaptive Resolution Imaging Sonar). The ARIS uses the same Didson technology to produce crisp and clear images. During Oceanology International, the Sound Metrics Corp featured the ARIS 3000 mounted to an X2 rotator in a water tank. With 128 beams operating at 3MHz, the ARIS Explorer 3000 collects more data than any other imaging sonar in its class. All of the ARIS Explorer models work in zero-visibility conditions and are built to deliver in the most challenging conditions. In addition, the small... (read more)
