This paper presents an overview of the latest developments in Sonardyne’s SPRINT-Nav family. Throughout 2025 and 2026 the SPRINT-Nav family has undergone a significant update, from introducing the world’s smallest hybrid navigator that was presented at Underwater Intervention last year to a complete update across the rest of the family – SPRINT-Nav M, I, S and X and beyond. Through this presentation Sonardyne will highlight how we’ve evolved SPRINT-Nav to meet the increasing demands and use cases of complete suite of marine robotic platforms.  

We will demonstrate real-world case studies of SPRINT-Nav performance with a focus on their impact on survey operations. Learn how the SPRINT-Nav family is enabling small inspection ROVs and micro AUVs to navigate and position to levels that enable them to take on tasks that previously called for larger and more capable platforms. Understand how uncrewed surface vessels can reduce their reliance on potentially spoofed or jammed GNSS aiding with SPRINT-Nav taking care of vehicle navigation in a GNSS independent solution. Discover how the new generation of ultra long range extra large UUVs can transit thousands of kilometres in mid deep water without the need to surface with a reliable and precise navigation payload onboard that means mission and data are solid.  

Finally, the paper will explore how collaboration with industry partners is positioning SPRINT-Nav as a critical enabler of increasingly remote and autonomous operations. Through interoperability with complementary technologies and ongoing innovation, SPRINT-Nav supports the transition toward smarter, more autonomous subsea systems, reducing operational costs while maintaining mission critical requirements that in today’s operations still rely heavily on human intervention.
