MAS vs SAS – When should we use multiple aperture sonar?

Why is Solstice different from other side scan sonars? Solstice is a Multi Aperture Sonar (MAS) which functions like a top performing traditional side-scan sonar but it is processed very differently. In this approach, the multi-beam input from 32 elements is dynamically focused to extend the focus along the whole length of the swath. By …

Seatronics increase investment in Sonardyne SPRINT hybrid navigation technology

Marine technology specialists, Seatronics, an Acteon company, has increased its investment in Sonardyne hybrid navigation technologies following the purchase of four SPRINT Inertial Navigation Systems (INS) and four Syrinx Doppler Velocity Logs (DVLs). The significant equipment investment, which also included six ROVNav 6 acoustic transceivers, will be added to Seatronics’ existing SPRINT rental pool in …

HYPACK adds support for Sonardyne Solstice sonar in hydrographic software packages

HYPACK, a Xylem brand, has announced that its market-leading HYPACK® MAX and HYSWEEP® hydrographic surveying packages can now be used to process and display data from Sonardyne’s Solstice side-scan sonar. With over 10,000 users around the world, HYPACK is the most widely used hydrographic software package in the world. The addition of the Sonardyne proprietary …

Indian tsunami detection network undergoes 10 year refurbishment

A network of deep water acoustic sensors which for the past decade has provided coastal communities around India with early detection of tsunami waves, has undergone major refurbishment by subsea technology company, Sonardyne International Ltd., UK. Deployed at key locations in the Bay of Bengal and Arabian Sea, the Sonardyne Bottom Pressure Recorders (BPRs) detect …

Deep BV takes delivery of Mini-Ranger 2 positioning equipment to support UXO surveys

Deep BV, a Dutch survey company specialising in hydrography, marine geophysics and oceanography, has purchased underwater acoustic technology supplied by Sonardyne International, UK, to support its inshore, harbour, coastal and offshore activities. The two Mini-Ranger 2 Ultra-Short BaseLine (USBL) tracking systems and WSM 6+ mini transponders were delivered to Deep BV’s headquarters in Amsterdam within …

SPRINT flies with Honeywell sensors inside

Author – James Barnett. INS System Engineer When our engineers came to select the ring laser gyros (RLGs) and accelerometers for our hybrid acoustic inertial navigation product family, inertial sensor manufacturer Honeywell was at the top of the list. Each SPRINT uses three Honeywell GG1320AN digital RLGs and three QFLEX accelerometers. Honeywell began production of …

Sonardyne inertial navigation selected for MBARI’s Ventana and Doc Ricketts ROVs

Subsea inertial navigation technology supplied by Sonardyne Inc., Houston has been selected by the Monterey Bay Aquarium Research Institute (MBARI), for its deep-rated remotely operated vehicles (ROVs), Ventana and Doc Ricketts. The SPRINT systems will be used in conjunction with MBARI’s existing Sonardyne Ranger 2 acoustic tracking systems to improve the accuracy, precision and integrity …

Map out the future of your surveys

Terrestrial mapping was revolutionised by aerial LiDAR. Using high-accuracy, post-processed GNSS-aided inertial navigation for geo-referencing sensor frame point measurements into ‘real world’ coordinates has enabled reliable mapping of large areas to high accuracy extremely quickly and cost effectively. Our SPRINT-Mapper technology now provides users with a similar subsea capability and set of advantages. Simon Waterfield, …

Hybrid navigation for subsea vehicles: Look no further than SPRINT-Nav

Author: Malik Chibah – Engineering Manager We hosted a live, in-water demonstration of our new SPRINT-Nav, acoustically aided inertial navigation system (AAINS), at our Plymouth trials facility, UK. We wanted to put our new technology through its paces, to really demonstrate why SPRINT-Nav will be the new industry leader in subsea vehicle hybrid navigation. Our SPRINT-Nav combines …
