The HPT 3000 Ultra-Short BaseLine (USBL) is a new smaller, lighter, high performance Ethernet interfaced USBL tracking transceiver, supporting Sonardyne’s Wideband®2 6G® instruments.

This smaller HPT offers significant improvements for survey positioning for coastal and near shore operations where high elevation tracking is required in low noise environments.

The advanced multi-element processing enables transponders to be positioned more precisely, more quickly and more robustly due to improvements in signal processing algorithms. When used as part of a complete Mini-Ranger 2 USBL system, heading and inertial navigation sensor, class leading performance is achieved.

The internal MTi-30 Xsens sensor provides pitch, roll and heading data for search and salvage applications which are time critical requiring turn on and track functionality. Shallow water and pipelay from anchor barges also benefit from the internal sensor being calibration free.

‘Discovery Mode’ enables users to automatically detect previously deployed transponders including their configured address and channel, making the system easier to use.

The HPT 3000 is a highly capable acoustic USBL tracking transceiver. Its multiple simultaneous channels enable robust tracking of 10 targets.

Manufactured in Aluminium Bronze, the HPT 3000 is intended to be fitted temporarily or permanently to a vessel’s through-hull or over-the-side pole.

The full hemispherical coverage optimises performance in shallow water environments boosting transmissions and receive sensitivity in the horizontal axis.

Being Ethernet based enables the system to function over existing ship network wiring for rapid installation.
