IXSEA's PHINS 6000 with DVL Ready

IXSEA recently launched PHINS 6000 with DVL Ready option, the latest version of IXSEA's subsea

Photonic Inertial Navigation System.

This fully calibrated system with a

DVL interface is designed to improve the USBL rejection filter for noisy environments (multi transponder) and has an LBL protocol. It is based on Fiber Optic Gyroscope (FOG) technology coupled with a digital sig- nal processor, which runs a Kalman filter especially developed for marine applications.

IXSEA Launches

Enhanced OCTANS

IXSEA launched a new version of

OCTANS, the IMO certified survey grade gyrocompass and full motion sensor, which is now Ethernet and wireless compatible. OCTANS now with Ethernet interface allows users to connect it to their network and any instrument or computer connected to this network will then be able to access its data. OCTANS is config- ured with Ethernet compatible repeater software that allows any

Ethernet network connected PC users to configure OCTANS. In addition,

OCTANS is able to provide real-time data at 200 Hz refreshing rate and to synchronize on UTC time using PPS and ZDA message from a GPS receiv- er.

Sonardyne Launches

AvTRAK 2

Sonardyne International Ltd. launched a new acoustic positioning and communications instrument for

Autonomous Underwater Vehicles (AUVs). AvTrak 2's comprehensive command language allows the vehicle to undertake a variety of survey tasks from LBL ranging, USBL tracking via a surface vessel and robust and high speed telemetry for AUV-to-surface and AUV-to-AUV communications.

AvTrak 2 aims to provide the AUV designer with absolute position refer- ence data to constrain the drift in his inertial navigation systems.

New Tsunami Detection

System

A system for providing advance warning of tsunami waves has been developed by Sonardyne

International Ltd. The Tsunami

Detection System can be deployed on the seabed in the deep ocean from where it will monitor the pressure of the water above it. A tsunami wave in deep water creates a small but meas- urable change in pressure that will be maintained for as long as 20 minutes.

By monitoring any such changes caused by a tsunami, the subsea detector will trigger an alarm that sends an acoustic warning message to a buoy-mounted transceiver on the surface. The transceiver, in turn, relays the message via a satellite data link to a control center.

Aquatscat 1000

Launched

The AQUAscat acoustic backscatter system has passed through several generations since the

AQ62 and AQ115 single- board PCbased data log- gers with a 20MB hard disk were first developed in 1992. The AQUAscat 1000 was launched at

Oceanology. It transmits high frequency sound at up to four different fre- quencies, using aligned transducers. It records the sound scattered back by www.seadiscovery.com Marine Technology Reporter 59
