Sonardyne HPT 3000: High-Performance USBL Transceiver

The Industry Standard for Shallow-to-Medium Depth Tracking & Telemetry

Product Overview

The Sonardyne HPT 3000 is a highly versatile acoustic transceiver designed for use with the Ranger 2 and Mini-Ranger 2 USBL systems. Operating in the Medium Frequency (MF) band, the HPT 3000 is optimized for tracking underwater targets—such as ROVs, AUVs, and divers—in water depths ranging from 1 meter to 3,000 meters.

What sets the HPT 3000 apart is its specialized acoustic array. Designed with a unique hemispherical beam pattern, it excels at tracking targets at high elevations (targets far behind or to the side of the vessel). This makes it the premier choice for "long layback" operations, such as towed sensor surveys and cable laying, where maintaining a stable acoustic lock is critical.

Why Choose the Sonardyne HPT 3000?

• Optimized for Shallow Water: The transceiver's design is specifically engineered to reject multipath interference, ensuring reliable tracking in ports, harbors, and near-shore environments.
• Wideband® 2 Digital Signal Processing: Utilizes Sonardyne’s 6G platform to deliver high-integrity data even in extreme acoustic noise (e.g., near vessel thrusters or heavy rain).
• Flexible Tracking: Supports tracking of both legacy (analog) and modern 6G (digital) transponders, providing a seamless bridge for aging subsea fleets.
• High-Speed Telemetry: Beyond positioning, the HPT 3000 acts as a robust underwater modem, allowing for the remote configuration of transponders and the retrieval of sensor data (depth, heading, etc.).
