Marine autonomy
As “underwater GPS” can’t exist, subsea vehicles rely on a variety of sensors to reliably navigate underwater. Our Doppler Velocity Logs (DVLs) are a crucial component of an underwater navigation system, providing speed over ground information and aiding in vehicle control.
High-performance underwater navigation solutions for any type of subsea or surface vehicle.
Underwater vehicles
From large work-class ROVs to portable or micro-AUVs, subsea vehicles need a DVL to reliably navigate underwater and to geolocate oceanographic survey data. DVLs are often integrated with other positioning sensors (e.g. INS) to provide these vehicles with a complete navigation system.
Uncrewed surface vehicles
Under certain conditions, a USV can lose access to its normal GPS navigation input. As a result, USVs often require backup from an underwater navigation system. DVLs are a cost-effective and efficient solution to this challenge.
Diver safety
Our compact and lightweight DVLs are integral to diver handheld navigation systems by tracking the position of divers on long-range underwater missions. They can also collect current profiles, which can be relayed in real time to ROV operators monitoring if water velocities are safe for divers.
