The future of maritime navigation with SPRINT-Nav DP 

18092025

GNSS spoofing and jamming are making headlines, globally. It's an increasingly real issue creating vulnerabilities for maritime operations, particularly when relying only on single or even multiple GNSS inputs as a position reference. 

Spoofing (transmits fake signals to deceive vessels about their true position) and jamming (blocking genuine signals to disrupt navigation) can compromise vessel efficiency and safety.

Whether deliberate or accidental, both can disrupt dynamic positioning (DP) Class 2 (DP2) operations, causing delays and potentially also posing significant risks, especially in busy and infrastructure-heavy waterways.

Spoofing and jamming can compromise vessel efficiency and safety.

Traditional vessel navigation systems, which underpin most DP operations, heavily rely on satellite signals, sometimes as a single position source and sometimes as multiple sources, to meet class requirements.

But if your signals are blocked, jammed or spoofed, you have a problem, especially during critical operations near offshore platforms or while conducting precise seabed mapping.

Relying soley on satellites, with their common vulnerabilities, for your vessel’s position isn’t always enough. While deploying seafloor hardware is an option, it adds time and can limit your operational footprint. This is where SPRINT-Nav DP changes the game.

SPRINT-Nav DP – a leap forward in maritime navigation

Building on a decade of proven performance in our SPRINT-Nav family of underwater navigation sensors, SPRINT-Nav DP is designed to deliver continuous, accurate positioning information even when GPS signals are compromised.  

It’s ideal for DP2 vessels working in shallow water and nearshore environments where GNSS signals are often blocked, distorted or unreliable.  

Whether it’s wind farms, risers or coastal structures causing interference, SPRINT-Nav DP ensures you stay on position when it matters most. 

With SPRINT-Nav DP continuosly running, you’ve also got that indepedent input, ensuring continuity of your position reference – disruption of which, if you’re suffering from outtages, can cause timing issues and even your AIS to drop out.  

Take a look inside

So, how does it work? SPRINT-Nav DP seamlessly integrates a high-grade inertial navigation system (INS) with our powerful Syrinx Doppler velocity log (DVL) and a precision pressure sensor.

This combination delivers independent, real-time positioning.  

When other systems drop signal, SPRINT-Nav DP holds its bottom lock, accurately tracking your vessel and maintaining your DP2 classification, so your operation doesn’t miss a beat.

There’s no need for seabed infrastructure or complex setup. SPRINT-Nav DP arrives pre-calibrated and ready to work straight out of the box.

SPRINT-Nav DP can be fitted via your standard through-hull deployment system or an over-the-side pole mount.

By using the DVL to reference the seabed up to 230 m below, you unlock a much larger operational footprint—ideal for dynamic projects like cable laying, offshore construction, or windfarm installation.

Dependable dynamic positioning

SPRINT-Nav DP delivers reliable performance exactly when you need it. Crucially, it means you can meet legal requirements for independent reference sensors in your DP2 operations, giving you confidence that your vessel is where it should be, even when satellite signal prove unreliable.

In a time when accuracy, safety and redundancy are critical, SPRINT-Nav DP is your dependable alternative, wherever your shallow water projects take you.
