Overview

Perfect fit and precision

The perfect balance between size and performance, SPRINT-Nav M (formerly SPRINT-Nav Mini) offers robust underwater and subsea navigation. It adds precision and reach to your operations. Your all-in-one vessel and marine robotics navigation instrument with real word results you can rely on. It replaces the need for separate AHRS, DVL, INS and depth sensors.

SPRINT-Nav M fuses AHRS, DVL, INS and depth data into a single, lightweight instrument, giving you fast, precise and robust navigation, guidance and control information. There’s less cabling and fewer connectors to keep check of too. Not only is it simpler to mobilise, it’s also cheaper than the four sensors it replaces.

The SPRINT-Nav M DVL also has the ability to gather ADCP data to help you understand water velocities and directions in your operational environment.

The perfect package for when you need reliable performance

Subsea navigation

SPRINT-Nav M is available in three depth ratings, 300 m, 1000 m and 4000 m. Measuring from just 187 mm in height (only fractionally taller than some competing DVL-only instruments), 148 mm in diameter and weighing as little as 3.6 kg in air for the 300 m rated unit, SPRINT-Nav M packs a big punch for all your ocean robot navigation applications.

It’s powered by the same hybrid acoustic-inertial navigation algorithm you’ll find inside the whole SPRINT-Nav family. This combines the strengths of all its sensors to provide robust, precise and accurate outputs. It continues to work even in challenging environments providing a continuous stream of positions, orientation, velocities, depth and altitude at up to 200 updates per second.

Ready to go – Pre-calibrated

Your SPRINT-Nav M arrives pre-calibrated, meaning there is no need to manoeuvre your vehicle every time the unit is mobilised, saving costly vessel time. SPRINT-Nav M does the thinking for you, all in a single plug-and-play unit. Turn it on, give it a latitude and away you go.

Despite its small size, it’s still a true north seeking gyrocompass that won’t drift over time unlike MEMS-based systems. The output can be fed directly to your own (or a third party) user interface or vehicle control software. The simple web user interface makes setup and configuration painless. It could not be any simpler.

Need to operate from coastal waters or around offshore structures? Not a problem! Low power and small, SPRINT-Nav M is ideal for installing on all size AUVs, ROVs or USVs undertaking missions, even in GNSS-denied environments.

Conducting marine research on a restricted budget? Let us help… Because it’s lower cost than the four separate sensors it replaces, SPRINT-Nav M is the budget-friendly solution for your research platforms where funds need to stretch as far as possible.
