Exail has secured the first sale of its Gaps M3 USBL (Ultra-Short Baseline) positioning system to a major offshore construction company in Asia, marking the first deployment of this advanced subsea positioning technology for a cable-laying project.
Engineered by Exail’s team, including Antoine Quazuguel and Product Manager Paul Urvoas, the Gaps M3 is tailored for nearshore and shallow-water operations where space, budget, and adaptability are key factors.
The Gaps M3 is an advanced USBL system with the ability to track subsea targets at high elevations, making it ideal for dynamic applications such as marine construction, pipeline installation, and cable laying.

The Gaps M3 was specifically selected for its ability to deliver high-precision subsea tracking while remaining cost-effective. Integrated with a vessel’s existing attitude and heading reference system, the Gaps M3 will provide the same accuracy as Exail’s high-end Gaps USBL models, offering a solution for operations that require reliable subsea navigation at a lower cost.
Lucy Xi, Regional Sales Manager at Exail, commented, “This first sale of the Gaps M3 reflects the growing demand for compact and affordable subsea positioning systems that maintain high performance. With its versatility, ease of deployment, and cost-effectiveness, the Gaps M3 is a valuable tool for offshore operators seeking efficient and accurate tracking capabilities.”
