Norway: iSURVEY Invests in Sonardyne SPRINT INS System

To improve the efficiency and capabilities executing Multi Beam Echosounder (MBE) seabed surveys and deep water marine construction support, the iSURVEY group now owns and operates the SPRING INS system.

SPRINT (Subsea Precision Reference Inertial Navigation Technology) is an acoustically aided inertial navigation system for subsea vehicles. The system extends the operating limits of Ultra-Short BaseLine (USBL) and can dramatically improve the operational efficiency of Long BaseLine (LBL) by using sparse arrays. SPRINT makes optimal use of acoustic aiding data from acoustic positioning and other sensors such as Doppler velocity log (DVL) and pressure sensors. This improves position accuracy, precision and integrity in any water depth while reducing operational time and vessel costs.
