Sonardyne’s Sonar on SubSea Craft's New Diver Delivery System

.SubSea Craft’s VICTA Class DDU offers the speed and endurance of a long-range insertion craft with the stealth and capacity of a swimmer delivery vehicle. It can travel up to 250 nautical miles (nm) at speeds of up to 40 knots on the surface, whilst submerged it cruises at 6 knots, with a ‘sprint’ capability of 8 knots, for up to 25 nm to deploy and recover up to eight operatives (two crew and six divers) to their objective area mission-ready.“Being able to detect – at range – navigation hazards, before they become a real threat, is mission-critical to the sort of

Sonardyne Unveils New Products

Underwater technology provider Sonardyne International Ltd. has announced new additions to its 2020 product line-up.With a focus on compact yet capable unmanned and vessel instruments, Sonardyne has unveiled SPRINT-Nav Mini, a compact guidance and control solution in the market, as well as ADCP functionality for its Syrinx Doppler velocity log (DVL) and a smaller, lighter version of its popular Gyro USBL transceiver.SPRINT-Nav Mini provides guidance and control outputs – orientation, velocity, altitude and depth – in a single instrument that weighs just 0.7 kg in water for the 300 m-rated

AUV Project Boosts Endurance, Navigation Capabilities

hybrid acoustic-inertial-Doppler navigation and communication solutions for AUVs and USVs, we were uniquely placed to collaborate with the NOC and L3Harris to realise the ambitious aims of the P3AUV project.“By developing and integrating each organisation’s technologies, including our own SPRINT-Nav navigation instrument, we’ve proven it’s possible for underwater platforms to make more of their available onboard power and maintain navigational accuracy over long distances without external aiding.“We’ve also proven the capability to autonomously calibrate networks

DOF Subsea Upgrades ROV Fleet

Subsea services provider DOF Subsea has equipped a further three of its Brazilian offshore vessel fleet with hybrid acoustic and inertial navigation technology from Sonardyne Brasil Ltda.Sonardyne’s SPRINT-Nav all-in-one subsea navigation instruments are now supporting five Forum Energy Technologies (FET) remotely operated vehicles (ROV) on board the three vessels. This latest order takes the total number of DOF Subsea’s Brazilian vessels equipped with SPRINT-Nav aided ROVs to six.SPRINT-Nav combines Sonardyne’s SPRINT sensor, Syrinx 600 kHz Doppler velocity log (DVL) and a pressure

the same time, the company’s BlueComm optical modems were used to support the world’s first television broadcast from an untethered manned submersible, as part of the Nekton First Descent mission in the Seychelles.Meanwhile, the company’s leading subsea hybrid navigation instrument, SPRINT-Nav, is helping to push the boundaries of long-range autonomous subsea navigation in partnership with the National Oceanographic Center (NOC). It’s already the instrument of choice for subsea resident vehicles and is supporting the most demanding autonomous underwater vehicle (AUV) applications
