Improved Efficiency for iSURVEY

iSURVEY will be using SPRINT to support a wide variety of multi-beam seabed surveys using deep-rated ROVs. The system has been developed by Sonardyne to exploit the long-term accuracy and precision characteristics of acoustic positioning techniques with the continuous availability and fast update rate of state-of-the-art inertial navigation sensors. SPRINT’s integrated solution offers considerable improvements for positioning subsea vehicles, both in terms of precision and reliability as the system can continue to provide a reliable out when acoustic techniques become marginal due to sea state, water depth or operating range.

Image: The core of SPRINT is the Lodestar inertial platform. The unit is depth rated up to 5,000 metres and has an in-built battery backup that can maintain inertial and AHRS algorithms for up to two hours if external power is lost.
