Datasheet
GDT USBL Transceiver

Sonardyne’s family of Fusion Ultra-Short 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 ±50º 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.

TitleDescription
Compatibility of New Digital USBL Transceiver with V6 LUSBL Software - No: 04-006 Some older versions of Sonardyne's L/USBL software do not allow sufficient time to allow a connection to be established to the latest generation of Generic Digital Transceivers (GDT).
LUSBL Transceivers - Use of Protective Covers - No: 04-012 A number of L/USBL transceivers have been returned for repair with damage to the front face where the damage appears to have been caused by transceiver being scraped along the vessel deck. It is apparent that this is occurring on portable systems where the transceiver is fitted on an over the side pole arrangement.
Cleaning USBL Transceiver Arrays - No: 08-008 Technical bulletin providing guidance on cleaning Sonardyne USBL transceiver arrays.
