Sonardyne HPT 5000 and 7000 USBL positioning and telemetry Transceiver
The HPT Ultra-Short BaseLine (USBL) and telemetry transceiver is a new high performance platform which supports Sonardyne’s Wideband®2 6G® instruments and offers significant improvements in acoustic positioning and telemetry performance.
Description
The advanced multi-element processing enables transponders to be positioned more precisely, more quickly and more robustly due to improvements in signal processing algorithms and array design. When used as part of a complete USBL positioning system such as Marksman or Ranger 2 and tightly integrated with Sonardyne’s Lodestar attitude, heading and inertial navigation sensor, class leading performance in all water depths is achieved.
New functionality, such as ‘Discovery Mode’ which enables users to automatically detect previously deployed transponders including their configured address and channel, makes the system easier to use.
The HPT also fully supports 6G LBL operations via Fusion LBL software. The HPT transceiver is also a highly capable acoustic telemetry transceiver. Its multiple simultaneous channels enable robust high speed telemetry reception from Sonardyne’s 6G subsea transponder modems and data loggers so reducing valuable vessel time.
Manufactured in aluminium-bronze, the HPT is intended to be fitted temporarily or permanently to a vessel’s through-hull or over-the-side pole.
A number of different array designs are available from full hemispherical coverage to specialist directional designs for ultra deepwater high noise environments.
