Sonardyne SPRINT-Nav 500

SPRINT-Nav is a high-performance hybrid navigation system designed for subsea vehicles and offshore survey operations. Available in 600 kHz and 400 kHz variants, it supports accurate seabed tracking across a range of operating altitudes.

The system integrates inertial sensors, a Doppler Velocity Log (DVL) and a high-accuracy pressure sensor within a single compact housing. This tightly integrated design delivers reliable positioning and motion data while maintaining a small footprint for easy integration with ROVs, AUVs and other subsea platforms.

SPRINT-Nav is supplied fully calibrated, enabling rapid deployment with minimal setup. Its dual AHRS and INS algorithms allow simultaneous navigation functions, such as supporting vehicle piloting while delivering high-accuracy survey navigation.

With tightly coupled beam-level DVL aiding and advanced quality control metrics, the system provides stable navigation even in challenging bottom-lock environments. Each DVL transducer is protected by a full depth-rated water block, ensuring durability and continued operation even if a transducer becomes damaged.

A single interface connection, combined with internal battery backup, ensures continuous navigation data logging and supports post-mission diagnostics and analysis.
