What is a Sonar Pulse and How Can it Injure Humans Under Water?
Last month, the Australian government revealed that its navy divers had sustained “minor injuries”, likely due to sonar pulses from a Chinese navy vessel.The divers had been clearing fishing nets from the propellers of HMAS Toowoomba while in international waters off the coast of Japan. According to a statement from deputy prime minister Richard Marles, despite HMAS Toowoomba communicating with internationally recognized signals, the Chinese vessel approached the Australian ship and turned on its sonar, forcing the Australian divers to exit the water.The incident prompted a response from
Kraken Robotics Supplies High-Resolution Seabed Mapping Sonar Solution to Australian Navy
Canadian marine robotics company Kraken Robotics said Monday it had supplied high-resolution seabed mapping sonar equipment to the Royal Australian Navy. Kraken delivered its KATFISH high-speed high-definition seabed awareness solution in Q2, and recently completed system integration and sea trials in Cairns, Australia. Kraken expects to provide additional in-service support including training, spares and operational support. "Continuing to build off successful KATFISH deliveries with various NATO navies, this represented Kraken’s first KATFISH system sale in the Asia-Pacific
NSSLGlobal Expands Portfolio with FarSounder’s 3D FLS
FarSounder and NSSLGlobal have joined forces to introduce FarSounder’s Argos product line to their defense, commercial, and leisure clients. These innovative Forward Looking Sonars (FLS) are used for safe navigation and obstacle avoidance. FarSounder’s technology is renowned in the cruise and leisure markets and is increasingly being adopted in both the Scientific/Exploration and Defence sectors both of which are moving towards Unmanned Surface Vessels (USV).Vessels are often operating in more challenging environments such as higher latitudes where there may be ice, poorly chartered areas
FarSounder Receives 8th Patent
FarSounder expanded its IP portfolio with the issuance of its 8th Patent, number 11,609,316. This US patent expands the company’s patent portfolio for its unique sonar system and its 3D processing.The invention provides a sonar system that includes a forward-looking sonar device that operates in an integrated fashion with one or more other sonar devices so that a boater can have a reliable navigation tool. The forward looking sonar can include a transducer array that takes a three-dimensional acoustic reading of the objects and seafloor ahead. The electronics that process the acoustic data can
MIND Technology earns MA-X Technology Patent
MIND Technology said that the U.S. Patent and Trademark Office granted a patent for MA-X technology. MA-X was engineered and designed by MIND's Klein Marine Systems unit and is an integrated single beam side scan and gap filler sonar.MA-X provides imaging of the nadir zone, or "gap", with the same interpretive characteristics of side scan sonar reportedly improving survey times by up to 40%. Klein's first product incorporating this technology is the MA-X VIEW 600. This system delivers focused 600kHz imagery (which is comparable to 900kHz resolution) with 100% bottom
EdgeTech Announces Major Order from ECHO81
EdgeTech said it received a 'significant' order from ECHO81 for its 6205s2 Bathymetry Systems, 4205 & 4125 Side Scan Sonar Systems, 3400-OTS Sub-Bottom Profilers, and 2050-DSS combined Side Scan & Sub-Bottom deep tow systems. The order, valued at more than $2 million, will be available for direct purchases from ECHO81.CHO81 is EdgeTech's exclusive partner and distributor in the U.S. and Latin America for the 6205s2 and 3400 product lines. In late 2022, ECHO81 also purchased EdgeTech's 3000m rated deep tow system, Model 2300, which is equipped with advanced Bathymetry
Seatronics Select ISS360HD Sonar
The ISS360HD Imaging Sonar provides a step change in performance in the scanning imaging sonar market. Providing a 2.5mm range resolution combined with a 1° angular resolution enables exceptionally high definition imagery from a highly compact sonar. With a range capability in excess of 100 meters the ISS360HD can suit a range of AUV, ROV and standalone underwater applications.
TDI-Brooks Upgrades Deepwater Multibeam
To enhance mapping efficiency, TDI-Brooks upgraded the multibeam (MBES) system on their vessel RV Gyre from the Kongsberg Maritime EM 302 to the EM 304 MKI. The EM 304 MKI is the successor of the highly acclaimed EM 302 which provides an increase of 75% swath performance at 6,000 meters. The EM 304 MKI can map shallow-to-medium water depths with high resolution and still map the deepest depths with great coverage.The modular EM304 MKI performs accurate, high resolution seabed mapping in shallow to deep waters at depths of more than 11,000m. The evolution of the EM 304, the EM 304 MKI broad range of
Kraken Gets $1.1M Synthetic Aperture Sonar Order for NATO Navy Clients
Kraken Robotics has secured a $1.1 million purchase order from an unnamed customer for several of its AquaPix synthetic aperture sonars SAS). "These systems will be integrated to Autonomous Underwater Vehicles (AUVs) for delivery to two distinct NATO navies. Delivery is expected in the first half of 2023." Kraken Robotics said .Kraken’s AquaPix is an off the shelf, configurable SAS that replaces high end sidescan systems at an, Kraken says, affordable price, while delivering higher resolution, range, and area coverage rates (ACR). Kraken says that the increased range
