The Problem With Current SSP Methods

High-precision sonar depends on accurate sound speed profiles — but collecting them typically means stopping the vessel or accepting significant trade-offs.

CTD / SVP Systems

Require the vessel to stop for each cast. Provide a profile only at that time and location — not continuously along the track.

Moving Vessel Profilers

Underway capable but require significant capital investment, deck space, and ongoing maintenance. High operational burden limits adoption.

XBT Probes

Single-use instruments with recurring per-cast consumable costs, limited depth, and limited resolution. Not reusable.

These limitations become even more significant in challenging environments such as high sea states and icebreaking conditions — exactly where accurate SSP matters most.
