| Sonardyne UK (Head Office) T. +44 (0) 1252 872288 F. +44 (0) 1252 876100 E. sales@sonardyne.com www.sonardyne.com Datasheet Fusion USBL Transceivers Description Sonardyne's family of Fusion UltraShort BaseLine (USBL) transceivers support the use of modern Wideband signal technology, offering improved noise immunity, increased dynamic range and greater accuracy. The Type 8021 transceiver offers a hemispherical pattern of acoustic coverage whilst still ensuring rejection of vessel noise. The transceiver allows tracking of targets from below and to the side of the vessel and it is suitable for a wide variety of survey tasks such as towfish tracking and ROV positioning. The Type 8023 transceiver is optimised to receive signals arriving within a 50 cone. Any noise generated outside of this area, for example by thrusters, is attenuated further, therefore improving the signal to noise ratio and so the positioning accuracy. In practise, this has been proven to allow the accurate positioning of the noisiest vessels. On quieter vessels, it enables even deeper depths to be achieved. The all new hardware platform on which the Fusion USBL transceivers are based means that the units can be easily upgraded remotely via a serial interface. They can also be used as Medium Frequency Long Baseline (LBL) transceivers when required. This removes the cost and inconvenience of installing and setting up a separate LBL transceiver when the need arises. Key features * Choice of transceivers depending on operating environment, water depth and vessel * Incorporates Sonardyne's latest Wideband(R) signal technology * Operates as an LBL transceiver for all MF frequency operations * Remote firmware upgrade via serial interface * Improved noise immunity and analysis * Non-Sonardyne frequencies supported Sonardyne UK (Head Office) T. +44 (0) 1252 872288 F. +44 (0) 1252 876100 E. sales@sonardyne.com www.sonardyne.com Specifications Fusion USBL Transceivers Feature Operational Frequency Transceiver Performance Electrical Communication Dimensions (LxDia) Weight in Air Weight in Water Options Note Type 8021 Type 8023 MF (18-36kHz) MF (18-36kHz) Operating Range Up to 7,000 Metres Up to 7,000 Metres Acoustic Cover 90 50 Optimised for deep water Range Accuracy Better that 0.2 metres Better that 0.2 metres Positioning Repeatability All transceivers tested to better All transceivers tested to better that 0.1% of than 0.1% of slant range 1 Drms slant range 1 Drms Maximum Power +48VDC (38V to 50V), can +48VDC (38V to 50V), can operate on operate on +24VDC (18V to 30V) +24VDC (18V to 30V) Typical 15W, Max 50W Typical 15W, Max 50W RS485, baud rate switchable RS485, baud rate switchable 456mm (17.95") x 225mm (8.86") 487mm (19.16") x 300mm (11.81") 28kg 41kg 13.5kg 20kg Tilted Array Adaptor Tilted Array Adapter The absolute accuracy of the system is dependent upon the quality of attitude and heading sensors, beacon source level, vessel noise, water depth, mechanical rigidity of the transceiver deployment machine and proper calibration of the total system using CASIUS Specifications subject to change without notice - 04/2008 |
