Syrinx is a 600 kHz Doppler Velocity Log (DVL) from Sonardyne for surface and subsea vehicles and is depth rated to 4,000 m. The adaptive bottom lock technology inside Syrinx provides consistency and reliability over challenging and changing topography and works at an altitude higher than 85% of the world’s subsea infrastructure. This reduces the amount of time a vehicle has to dive on free inertial.
A highly capable and versatile Doppler Velocity Log
Syrinx can be used as a standalone DVL, as part of an integrated system, or perform both functions at once due to concurrent Ethernet and serial outputs, capable of ping rates of up to 25 Hz. Its dual capability means that only one DVL/altitude sensor is required for both ROV control and survey crews, saving on cost and vehicle payload space.
The unit runs an embedded DVL Manager using a web browser, eliminating the need to install dedicated PC software. This allows Syrinx to be configured and tested prior to deployment, and then during subsea operations, controlled and navigation data is easily visualised. The hardware and vehicle interfacing has been designed to be easy to install, set up and use and is compatible with DVL mounting arrangements from third parties. With similar dimensions to existing DVLs, there should be no need for modifications to subsea vehicles in order to upgrade to a Syrinx DVL. PD0, PD3, PD4, PD6, PD13 telegrams are supported for integration to third party navigation systems.
