Founded in Sweden over 35 years ago, Qualisys provides high-precision optical motion capture systems for marine and offshore research across indoor labs, outdoor ranges, and underwater environments. Our marine-rated hardware (IP67/IP68) enables seamless above- and below-water tracking through a coordinated twin-domain system, delivering continuous 6DoF measurement across the air-water interface.
Designed for basins, tow tanks, and open-water testing, our pressure-tested underwater cameras operate reliably to depths of 40 m. Lightweight markers enable precise tracking of vessels and appendages with sub-millimeter positional accuracy and rotational accuracy down to 0.1°.
The system supports large-volume tracking (100+ m), multi-rigid body capture, and deterministic time synchronization with DVL, INS, sonar, and other onboard sensors. Open ROS and Python SDKs allow real-time streaming over TCP/UDP for closed-loop testing and autonomy evaluation.
From single vehicles to multi-agent operations, Qualisys delivers scalable, sensor-fusion-ready workflows for AUVs, USVs, mooring systems, control surfaces, and subsea instrumentation — without tethering that alters hydrodynamics.
