Overview

Compact. Accurate. Ready to go.

All the navigation, speed, direction and motion data you need in one compact unit. SPRINT-Nav is perfect for your autonomous subsea or surface vehicle navigation operations. From deepwater ROVs to shallow water USVs, SPRINT-Nav ensures ultimate accuracy. It’s even pre-calibrated, so you can start working right away.

Find out what's possible

SPRINT-Nav is a compact, all-in-one navigation tool for underwater and surface vehicles, integrating SPRINT INS, Syrinx DVL, and a high-accuracy pressure sensor. Available in three performance levels (I, S and X) and two depth ratings (4,000 m and 6,000 m), it offers two DVL frequencies: 625 kHz and a high-altitude 375 kHz option.

Its Inertial Measurement Unit (IMU), featuring Honeywell ring laser gyros and accelerometers, works closely with the Syrinx DVL and a high-performance pressure sensor. This integration ensures unparalleled accuracy and reliability.

SPRINT-Nav saves time, costs, and payload space while offering unmatched performance and reliability for a wide range of subsea and surface vehicle applications.

Select the performance level right for your operation

SPRINT-Nav I: Supports dual ROV and survey use, standalone ROV guidance and mid-water station keeping with vendor independent USBL aiding.
SPRINT-Nav S: For more demanding applications, such as laser or multi-beam survey, this high-performing, survey-grade SPRINT-Nav is integrated with Sonardyne acoustics to provide you with the extra data functionality you need.
SPRINT-Nav X: Offers you exceptional navigational accuracy (<0.01% of total distance travelled) and ultimate suitability for long-endurance missions with XLUUVs, AUVs and USVs, making them viable alternatives to large, crewed vessels. The top-tier model for your specialised energy, defence and science operations.
