54 MTR January 2007 Sonardyne Offers Enhanced USBL Options Sonardyne International Ltd. of Yateley, U.K. released a major upgrade to its Fusion USBL (Ultra- Short BaseLine) acoustic positioning software to include its new Ranger USBL technology, to be offered in January 2007. By receiving Ranger software as part of a Fusion USBL system, operators have the freedom to use the application that best suits their particular needs at the time; Ranger for simple survey and Dynamic Positioning (DP) reference and Fusion for complex, deep water positioning tasks. Ranger is the latest addition to the Sonardyne USBL product family and is ideal for opera- tors with limited experience. The sys- tem is easy to learn, set-up and oper- ate. It offers simultaneous tracking of targets with a one second update rate independent of water depth. An important new feature available in both Fusion and Ranger is the abil- ity to undertake inverted USBL (iUSBL) tracking of towfish over super-long laybacks. With this method, the transceiver is not installed on the vessel but on the towed body itself that is often several kilometers behind and below the ship. Mounting the transceiver in this way eliminates the need for repeated system calibration while the accuracy and repeatability of the acoustic sig- nals are improved as the transceiver is located in a low noise, dynamically stable environment.

The ultra bright 10.4- in. display is designed to make side scan images easy to see, even on a sunny day. When the case is opened for operation, the control panel and display are sealed to protect them from moisture and all external cable connectors are O-ring sealed to pre- vent water intrusion. The computer has a 600MHz processor, a 60GB hard drive, and 512MB of RAM. A waterproof keyboard and mouse are included.

BlueView worked with commercial and U.S. Navy divers to develop a compact sonar that offers both mid-range detection as well as close-range identification capabilities. The P900E is available as a stand-alone sensor for custom inte- gration, or as a prepackaged component on several ROV, diver hand-held, and boat mounted systems. The P900E is designed to produce real-time sonar imagery at up to 10 full images per second, providing imagery of both stationary and moving targets. It is designed with a maximum range of 180 ft. and resolution as fine as one in., and can help detect and track targets at long ranges, while identifying them at closer ranges. With its standard Ethernet interface, wide input voltage range, and compact size, the P900E integrates easily into most systems.
