Sonardyne Unveils Fusion 2

(simultaneous localization and mapping) calibration of a sparse LBL transponder array while you survey – until now a lengthy offline post-processing activity.Significantly reducing survey time is central to another key innovation that arrives with Fusion 2. Sonardyne has reengineered the digital signal processing protocols used by Fusion 2 to command and control seabed arrays of its Compatt LBL transponders and vehicle-mounted ROVNav transceivers to Wideband 3.Wideband 3 allows, for the first time, sensor data (e.g. pressure, depth and temperature) from a Compatt to be to be embedded with navigation

Kraken Awarded $1 Million Defense Contract

Warfare Suite Upgrade, the Canadian Surface Combatant program and other international underwater surveillance programs.Kraken’s Acoustic Signal Processing Group has 80+ years of combined experience in sonar systems development and integration. Their core competency is implementation of digital signal processing and user interface software for Anti-Submarine Warfare (ASW) sonar applications. This work frequently involves integration with embedded processing platforms for shipboard or shore-based analysis systems. The group can process and display data from fixed and mobile underwater as well as

iXblue Equips Manned Submersible for Titanic Mission

;s long range and high accuracy USBL system that is operated from the surface ship and will be calibrated thanks to a Phins surface INS. Designed to track subsea vehicles to depths of 6,000 meters at ranges reaching over 10,000 meters, Posidonia uses advanced acoustic modulation, as well as digital signal processing technology and operates in the low frequency band for deep sea tracking operations. To communicate with Posidonia during each dive, Titan is equipped with iXblue’s MT8 compact low-frequency transponder.“Everyone at iXblue is very excited to be part of the Titanic Survey Expedition

in most water conditions. The vehicle weighs in at less than 50 pounds, including all instrumentation. A collapsible sliding crossbar makes the Z-Boat 1250 easily transported by a single operator.   The vehicle’s integrated single beam echosounder has an embedded transceiver with digital signal processing and outputs depth & temperature using NMEA 0183 data output.   The “exceptionally rugged” Z-Boat 1250 design features a propulsion system that uses two thrusters (one in each outrigger) and an advanced 2.4 GHz remote control transmitter that differentially adjusts

; effect on the voice which complicates the communication process. Early helium speech unscramblers created a lot of distortion which made it difficult for reliable diver communication. The HeliCom Matrix achieves superior, crystal-clear diver helium voice communication through advanced DSP (digital signal processing) helium speech decoding techniques. The helium speech from the pressurised divers and the chamber occupants are mixed in an audio mixer before decoding to the selected gas and environmental settings by a digital signal processing circuit (DSP). This has been the key element of HeliCom&rsquo

real-time, while producing detailed 3D imagery of the seafloor. Kraken’s RTSAS is a rugged, small-form-factor subsystem that incorporates an NVIDIA Kepler GPU. This kind of graphics processing capability is increasingly being applied in the aerospace and defense industry for complex digital signal processing. The RTSAS architecture has been designed from the ground up not just for maximum imaging performance but optimal performance per watt. The result is world class performance and the highest image quality in an elegant and power efficient unit. In essence, the GPU acts as a massively
