Fly higher. Navigate deeper. Profile in a single ping
Use Syrinx as a standalone DVL or ADCP, as part of an integrated navigation system, or perform all these functions at once. Built in the UK for easy export, it maintains bottom lock at up to 230 m altitude, supports dual outputs, has replaceable transducers and comes in a 4,000 m (400 kHz and 600 kHz), 6,000 m (600 kHz) or OEM housing. How does your current DVL compare?
Syrinx is a class leading Doppler velocity log (DVL) for surface and subsea vehicles, available in two frequencies; 600 kHz or 400 kHz for higher altitude tracking up to 230 m. The Syrinx variants combine high resolution and high altitude tracking, in single, easy to install navigation instruments. 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. If water profiling is a mission requirement, Syrinx’s highly capable ADCP mode enables navigation and profiling without the need for separate instrument, saving you cost and payload.
When tightly integrated with Sonardyne’s INS, SPRINT, unmatched DVL-aided navigation can be achieved. This allows for enhanced performance through optimisation of beam-level data passed between Syrinx and SPRINT to aid velocity prediction and outlier rejection, with positioning able to continue even if one or two DVL beams are unavailable.
For the ultimate integration Syrinx and SPRINT are also available as a single combined unit with integral pressure sensor. SPRINT-Nav is one of the smallest inertial DVL instruments available on the market suitable for almost any ROV and survey task.
Syrinx runs an embedded System Manager using a web browser, eliminating the need to install dedicated PC software. This allows configuration and testing of Syrinx prior to deployment, control of Syrinx during subsea operations, and visualisation of the navigation data.
The hardware and vehicle interfacing has been designed to be easy to install, set up and use and is compatible with DVL/ADCP mounting arrangements from other vendors. With similar dimensions to existing DVLs and ADCPs, there should be no need for modifications to subsea vehicles in order to upgrade to Syrinx. PD0, PD3, PD4, PD6, PD13 telegrams are supported for integration to third party navigation systems.
A 4,000 m rated titanium housing is supplied as standard to meet the requirements of Work-class ROVs. 6,000 m and OEM (no housing) versions are also available. Syrinx’s transducers have been designed, built and tested in-house to provide maximum performance, and can be individually replaced, reducing ownership costs and repair time. The entire array is water blocked meaning that should damage occur to the transducer array, the unit’s electronics are isolated from water ingress.
Syrinx is designed and manufactured entirely in the UK. This means it can be exported to countries within the European Union and selected others (including the USA) without the need for a specific export licence.
