Find out what's possible

As with all SPRINT-Nav products, SPRINT-Nav U fuses AHRS, DVL, INS and depth data. All of this is now available in a single, ultra-compact and lightweight instrument giving you fast, precise and robust navigation, guidance and control information.

SPRINT-Nav U surpasses expectations in every way. With fast alignment, one unit, one connector, one cable and all the true-north seeking capabilities found across the SPRINT-Nav Family.

Game changing new capabilities for small robotic operations

Measuring just 134 mm in height and 114 mm in diameter and weighing a mere 600 grams in water, SPRINT-Nav U packs full SPRINT-Nav capability into the space traditionally filled by just a DVL on small subsea robotic platforms. With its compact fibre optic gyro (FOG) Inertial Measurement Unit (IMU) SPRINT-Nav U is a game changer for small vehicle operations.

It’s powered by the same trusted hybrid acoustic-inertial navigation algorithm you’ll find across the whole SPRINT-Nav family. This combines the strengths of all its sensors to provide robust, precise and accurate outputs. SPRINT-Nav U continues to work even in ferrous environments where Micro-Electro-Mechanical Systems (MEMS) based navigation, with its magnetic heading, struggles. This means your operations are provided with a continuous stream of positions, orientation, velocities, depth and altitude even when operating in and around infrastructure.

Ready, set, go

Your SPRINT-Nav U arrives pre-calibrated, meaning there is no need to spend valuable time conducting in-field calibration manoeuvres every time a vehicle is mobilised. It’s the fastest aligning subsea navigator available in the market. Arrive on site, turn it on, give it a position and away you go.

SPRINT-Nav U uses the same, familiar and simple web user interface as the SPRINT-Nav Mini, meaning its already user tested, field proven and has ease of use built in. As is standard for SPRINT-Nav products, the output can be fed directly to your own (or a third party) user interface or vehicle control software.

Need to do an ROV inspection of your offshore energy structures or ports and harbour infrastructure without deploying a large-scale vessel? SPRINT-Nav U will ensure accurate and continuous survey grade navigational data that is unaffected by the materials in such structures.

Conducting a seabed survey with your small AUV, Towfish or USV? No longer worry about the quality of the data you’ll get back as SPRINT-Nav U provides unparalleled navigational inputs for GNSS denied small vehicles and their payload sensors for accurate data collection every time.

Carrying out multiple surveys across a wide area? SPRINT-Nav U’s compact size and weight make it easily man-portable, deployable and retrievable from the back deck of a larger vessel.

What's possible

GNSS is your trusted DP reference input. But what if that signal vanishes? Don't let a dropped connection halt your operations Introducing SPRINT-Nav DP – your ultimate second dynamic positioning system.

Forged from a decade of proven excellence with our SPRINT family, this cutting-edge system seamlessly integrates INS and DVL technology, delivering an unshakeable DP reference, especially in GNSS-denied environments. SPRINT-Nav DP is crucial for the growing demands of shallow water operations, ensuring pinpoint accuracy and rock-solid reliability, keeping you on course no matter what. Like all our SPRINT-Nav product family, it’s pre-calibrated, so you can start working right away.

Built for DP class 2, and above operations, its Inertial Measurement Unit (IMU), featuring Honeywell ring laser gyros and accelerometers, works closely with the Syrinx DVL and the pressure sensor. This integration ensures unparalleled accuracy and reliability when dynamically positioning your vessel.

SPRINT-Nav DP saves time and costs while offering unmatched performance and reliability for a range of applications. With SPRINT-Nav DP, you don’t need to deploy other equipment such as transponders or reflectors as the Syrinx DVL locks onto the seabed for its positioning reference. This also increases the operational footprint of your vessel, which is otherwise limited in range or by weather conditions when using sensors.

Using bottom lock on the seabed, alongside pre-calibration, means that SPRINT-Nav DP is operational and can provide your position references as soon as it arrives on site. This makes it ideal for a wide range of shallow water and nearshore operations where GNSS signals are often spoofed, blocked or distorted by nearby structures such as turbines and risers or coastal geography.

Why choose SPRINT-Nav for your DP operations?

Realising the value from tightly integrating high grade INS with other aiding sensors, Sonardyne was the first company to market a hybrid acoustic-inertial family of products for subsea and surface applications – SPRINT-Nav.

The SPRINT-Nav family of instruments has been providing reliable navigation for ROV’s, AUV’s, and USV’s for more than a decade in the harshest of subsea environments, where precision, accuracy and reliability is paramount, and where there is no GNSS signal to depend on.

Renowned for dependable performance, they are the standard fit on hundreds of vehicles operating in the subsea domain. This experience, technology and expertise have led to the development of SPRINT-Nav DP for vessels operating in shallow water where a GNSS signal can’t be relied on.

By law, ships using dynamic positioning must have a number of independent position reference sensors, using different principles, to safely determine and maintain their position. This is known as “meeting class” and the number of independent references required depends on the type of class vessel. Most DP vessels operating in shallow water are class 2.

In shallow water operations, it can be a challenge to meet the requirements for independence and diversity of reference sensors. This can lead to an over reliance on multiple GNSS systems with their common vulnerabilities and failure points.

Removing the need for GNSS to give a DP reference by introducing SPRINT-Nav DP provides you with assurance that your positioning isn’t entirely reliant on a GNSS signal and will therefore still “meet class” in GNSS denied areas. Enabling you to operate safely and within the law.

Designed to work in any depth

From less than 1 m in the transition and surf zones to 3000 m for ultra-deep-water seismic applications.

Our shallow and deep rated acoustic positioning systems improve the speed, accuracy and efficiency of positioning seabed marine seismic nodes and cables, enabling the positioning of thousands of transponders in parallel with deployment and shooting operations.

The system uses a network of low cost, rugged transponders that can withstand fast deployment through mechanical ‘squirters’ to provide users with an efficient method of collecting the positions of thousands of seabed nodes in real-time.

A typical system comprises of acoustic positioning transponders attached to the seismic node or cable and a vessel or USV based acoustic range only or full USBL transceiver interfaced to a PC running our HydroPos seismic positioning control software application. Third party software applications that incorporate an acoustic control module can also be used with the system.

Once the nodes are deployed on the seabed, the system precisely measures the acoustic range (distance) or 3D position (USBL) from a surface transceiver on the pinging vessel to each transponder to enable its exact position to be established. The range and USBL positioning processes are more accurate than traditional first break techniques, 1-2 m absolute, and can either be conducted during node or cable deployment operations or later whilst shooting.

It can be provided in 1,000m and 3,000m depth rated housings and is fitted with a handy Near Field Communications (NFC) link as standard for programming and battery status checking.

RT 6-1000 is a release transponder option for this system. It incorporates an acoustic release mechanism and is typically used at rope or cable ends to aid recovery of seabed seismic equipment after shooting is complete.

Both SST 6 and RT 6-1000 are MF band transponders, compatible with our family of Ranger USBL acoustic positioning systems.

Transceivers

Two surface transceiver options are available for this system. TZ Transceiver (TZT) is small and lightweight making it perfect for use vessels-of-opportunity and uncrewed surface vessels which are increasingly being used in support of offshore seismic operations. It can operate in the HF or MF frequency band.

TZT is able to interrogate and calculate acoustic ranges to nine TZ Transponders or 95 SST 6 transponders at a time.

HPT 2000 (HF) and HPT 5000 (MF) are USBL transceivers configured to measure range and bearing to TZ Transponders and SST 6 transponders respectively. They are particularly well suited to high elevation tracking scenarios and offers true simultaneous tracking of multiple transponders providing superior position update rates.
