Sonardyne Global Headquarters T. +44 (0) 1252 872288 F. +44 (0) 1252 876100 E. [email protected] www.sonardyne.com Datasheet Syrinx – Doppler Velocity Log Description The Syrinx DVL is a class leading Doppler Velocity Log that builds on Sonardyne’s existing product range of acoustic instrumentation by bringing to market a high integrity, high performance instrument. Syrinx can be used as a standalone navigation instrument or can be integrated into Sonardyne’s SPRINT system or other 3rd party navigation systems. This new DVL provides the best of both worlds in a single unit. With a large altitude range and high precision at all altitudes, this combines the best of 300 and 1200 kHz DVLs. Syrinx utilises both Doppler and Correlation technology to gain performance advantages in environments where each technology is best suited. Processing techniques have been refined to avoid any loss in output measurements including undulating and sharp roll off terrain of any type. The instrument has been tested over terrains with near vertical gradients to ensure velocity estimates are always provided, even when individual beam data can show vast differences in altitude. Adaptive signalling techniques utilise the best signal type for the environment and terrain, this allows both low and high altitude class leading performance. Syrinx allows users to simultaneously output data of different formats, so you can provide the ROV crew with one data format and your survey crew another. This reduces the requirement of more than one DVL on board the ROV, saving on weight and costs. Sonardyne have developed the transducers to be singularly interchangeable, dramatically reducing maintenance costs and times.
