Diver

Designed for shallow‑water, high‑noise environments, our diver‑focused transponders provide reliable acoustic tracking without adding complexity or workload for the dive team.

DiveTrack transponders power real‑time diver tracking and two‑way acoustic communication, giving supervisors clear visibility of diver location and status throughout an operation. Compact, diver‑mounted and purpose‑built for safety‑critical use, DiveTrack adds an extra layer of control to commercial, defence and scientific diving.

For simpler tracking tasks, the Nano USBL transponder offers lightweight, unobtrusive diver positioning using Sonardyne USBL systems — ideal for coastal operations, search and recovery and inspection work.

AUV

Designed for autonomous operations in challenging subsea environments, Sonardyne’s AUV transponders deliver reliable acoustic positioning, navigation aiding and telemetry from coastal surveys to long‑range missions.

AvTrak transponders underpin Sonardyne’s AUV capability, combining tracking, navigation aiding and two‑way acoustic communications in a single, vehicle‑mounted unit that maintains accurate position, receives surface updates and supports multi‑vehicle operations.

For smaller or space‑constrained platforms, Nano‑based transponders offer compact USBL tracking and relocation in a lightweight solution for recovery, inspection and nearshore use.

ROV

Designed for offshore operations, Sonardyne’s ROV transponders deliver accurate acoustic positioning in noisy, complex environments — from shallow‑water inspection to deep‑water construction and intervention.

WSM 6+ transponders provide fast, reliable USBL tracking, giving operators real‑time position awareness from the surface. Compact, rugged and optimised for multipath conditions, WSM 6+ is trusted for everyday ROV tracking across survey and IRM operations.

For higher‑precision work around subsea structures, ROVNav 6+ adds LBL and Sparse LBL capability directly to the vehicle, supporting accurate navigation, metrology and installation where positioning integrity is critical.

Structure & seabed

Designed for long‑term deployment on the seabed, Sonardyne’s structure and seabed transponders deliver stable, high‑integrity acoustic positioning for construction, metrology, monitoring and dynamic positioning — in all water depths.

Compatt transponders form the backbone of LBL and Sparse LBL networks, providing precise, depth‑independent positioning for subsea structure installation, pipeline and spool‑piece metrology and INS‑aided operations.

For vessel station‑keeping and rig positioning, DPT transponders act as reliable seabed references for DP systems, supporting multi‑vessel operations and reducing risk during critical offshore activities. Integrated acoustic release options enable efficient deployment and recovery without ROV intervention.

Towfish

Designed for dynamic survey environments, Sonardyne’s towfish transponders deliver reliable, real‑time acoustic positioning despite vessel motion, cable dynamics and acoustic noise — helping operators maintain confidence in towfish location and sensor data quality.

WSM 6+ transponders provide fast, robust USBL tracking of towfish and towed bodies, supporting accurate navigation during side‑scan, sub‑bottom and magnetometer surveys. Built on Sonardyne’s Wideband® 2 technology, WSM 6+ offers strong multipath resistance and rapid update rates for stable tracking at tow speed.
