USBL
solutions
With systems deployed worldwide, the Gaps Series high-accuracy USBL acoustic positioning and communication systems have become a trusted solution for users across the globe. Renowned for its unparalleled horizontal tracking capabilities and exceptional performance from ultra-shallow waters to depths of 7,000 meters, the Gaps Series supports diverse applications, including diver tracking, work-class ROV surveys, AUV missions, and even the most demanding dynamic positioning operations.
Powering ultra-performance subsea positioning and communication
Unmatched positioning accuracy
The Gaps Series delivers unparalleled subsea positioning accuracy (≥ 0.06% CEP50) in diverse and challenging environments. Its unique design integrates a high-performance ultra-short baseline (USBL) with FOG-based and MEMS motion sensors in a single housing.
True horizontal tracking
A versatile and easy-to-use system
A scalable range for every operational need
The Gaps Series provides a versatile suite of solutions designed to meet the diverse
demands of modern maritime operations. With three distinct models, the series
is tailored to deliver precision and reliability across a wide range of
