HPT 3000 is a  high performance Wideband 2-enabled Ultra-Short BaseLine (USBL) tracking and telemetry transceiver compatible with our range of 6G transponders.

The transceiver’s acoustic performance is optimised for operations in coastal and near shore where high elevation tracking of targets is often required in low noise environments.

This unit is easy to install on a simple over-the-side pole arrangement enabling a wide range of vessels to take advantage of Mini-Ranger 2 including; anchored barges, small survey craft and uncrewed surface vessels.

HPT 3000 has an internal MTi-30 Xsens sensor which 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.

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, external heading and inertial navigation sensor, class leading performance is achieved.

‘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.

Power and communications are contained in a single cable and because communications from the transceiver to control-room ESH, data rates of up to 100 Mps can be achieved.  Ethernet-based communications also enable the unit to interface with your vessel’s existing  network for rapid installation.
