Sonardyne Technology Selected for New Oceanographic Research Vessels
.Led by Oregon State University, the RCRVs are being built for the US' Academic Research Fleet (ARF), enabling a new era of coastal and regional marine science. To support the RCRV's scientific missions, across diverse marine environments, Oregon State University selected Sonardyne's Ranger 2 Gyro USBL 7000, engineered to meet both the demanding, multidisciplinary research objectives of the ARF and vessel-build requirements.The first system has recently been delivered to Oregon State University to be fitted to the R/V Taani, to be operated by the university, by vessel builder Bollinger
Deeply Innovative: Drivers in Subsea Defense
are pioneering solutions that enable navies to create highly integrated and distributed subsea networks.Sonardyne has long been a leader in subsea communications and positioning. Its BlueComm optical modem provides high-speed wireless data transfer between vehicles or from vehicle to surface, while their Ranger 2 USBL and Compatt 6+ LBL systems can double as communications networks, enabling AUVs, ROVs, and divers to share navigation data and mission updates.EvoLogics pushes acoustic communications further with its patented, dolphin-inspired S2C (Sweep Spread Carrier) technology, which offers simultaneous
