objective is to achieve a baseline accuracy below 0.5 meters, which requires a large array of high definition filming and sensing equipment.The necessary array aboard the Leopard includes three HD cameras with movie quality 1080i interlacing, two Kongsberg M3 profiling sonars, Sonardyne Mini-Ranger and SPRINT-Nav 500 Hybrid INS, Valeport bathy suite including altimeter, Valeport mini sound velocity profiler, MCS’s photo-realistic 3D cloud system, laser line generator, CP and UT probes.When long excursions are necessary the operating vessel must stay around 70 meters clear of platforms for safety

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

Neptune Adopts Sonardyne’s All-in-one Platform

be Sonardyne’s latest ‘plus’ hardware platform (6+), engineered to unlock the full capabilities of Fusion 2.Built from the ground up, with ease of use and operational efficiency in mind, Fusion 2 software offers a seamless environment in which surveyors can perform all of their LBL, SPRINT INS (inertial navigation system) and sparse (INS-aided) LBL operations. When used alongside 6+ hardware, Fusion 2 offers the ability to simplify complex projects - all with less subsea and topside hardware.As part of the deal, Neptune is trading-in its inventory of Compatt 5 seabed transponders which

Sonardyne Equips Latest Oceaneering Vehicles

Sonardyne announced Tuesday it has received an order from Oceaneering International to provide hybrid navigation systems for its subsea resident vehicles Freedom and E-ROV.  The two resident vehicle systems are to be fitted with Sonardyne’s SPRINT-Nav an all-in-one navigational instrument. SPRINT-Nav combines a SPRINT INS sensor, Syrinx 600 kHz DVL (Doppler velocity log) and a high accuracy intelligent pressure sensor in a single unit, Sonardyne said.Oceaneering’s E-ROV has already proven the ability for battery powered remotely operated vehicles (ROVs) working in the oil and gas

Center (NOC), has selected high-performance hybrid navigation technology from Sonardyne International Ltd. for the next generation of its Autosub autonomous underwater vehicle (AUV), targeted for under-ice operations.The NOC, based in Southampton, will incorporate Sonardyne’s highest performing SPRINT-Nav inertial navigation system (INS) into the new 2,000 meter depth-rated Autosub, which is being specifically developed for carrying high-performance sensors on the most demanding research missions under polar ice, hence its name Autosub2KUI, or A2KUI.SPRINT-Nav combines Sonardyne’s SPRINT

powerful customizable user interface and flexible operating environment, letting surveyors work how they want and see the information they want, when they want.”Fusion 2 is being rolled out in two releases. The Fusion 2 INS pack, released today, delivers LBL aided operations using Sonardyne’s SPRINT INS technology. The second release, due in Q2 next year, will deliver the full acoustic LBL package. The Fusion 2 system works through Sonardyne’s Navigation Sensor Hub (NSH), which also supports the company’s Ranger 2 USBL system, so users will need fewer systems in their inventory and

sensors.  Geraint West, Global Business Manager - Oceanographic, Sonardyne said, "The accuracy of low-power sensors degrades over time and AUVs consequently often have to surface to reinitialise with a GPS fix. However, by including high-performance, high-power navigation instruments, like our SPRINT INS, and integrating them with the low-power instruments to dramatically reduce power consumption, vehicle operators will get the best of both worlds, which will enable longer-duration independent deployments."
