Sonardyne's family of Fusion UltraShort Base Line (USBL) transceivers support the use of modern WidebandTM signal technology, offering improved noise immunity, increased dynamic range and greater accuracy. As well as providing all the standard features of Sonardyne's well proven USBL technology (see separate datasheets for Type 8021 & Type 8023 transceivers), the Type 8091 Inverted USBL transceiver provides the added flexibility of being able to mount the transceiver on an AUV, ROV, or deep towed body for use up to full ocean depth. Mounting the transceiver in this way offers many operational benefits. Installation is simple when compared with installing a through-hull or over-theside USBL transceiver. iUSBL Positioning Technique Vehicle mounted transceiver positioning a vessel mounted transponder The transceiver can be mounted at any angle from horizontal to vertically upwards allowing innovative, previously difficult tracking operations to be carried out, e.g. towed body to streamer tracking, ROV to ship tracking etc. Key features * Full ocean depth rated USBL transceiver * Can be mounted on an AUV, ROV or deep towed body * Incorporates Sonardyne's latest Wideband Technology * Non-Sonardyne frequencies supported * No need for second vessel to position the towfish Closely coupled attitude sensors eliminate the need for repeated system calibration, whilst the accuracy and repeatability of the acoustic signals are improved, as the transceiver is located in a low noise, dynamically stable environment.
