DVL family of navigation instruments

For ROVs, AUVs and USVs. Standalone or combined navigators to save you payload.

Our Doppler velocity logs (DVLs) underpin navigation for your surface and underwater platforms with high precision velocity measurements over a wide range of seabed types and altitudes.

Standard output telegrams make it simple to integrate them into third party navigation systems, whilst industry standard output telegrams support separate use by ROV and survey teams. Choose between a standalone 600 kHz Syrinx or SPRINT-Nav; our family of all-in-one DVL-inertial hybrid navigators.

Syrinx And SPRINT-Nav. Track Down Our DVL

Updating your vehicle’s DVL is easy; we’ve designed Syrinx to be a straight replacement for popular models

Fly higher, explore deeper. Our DVLs maintain bottom lock at high altitude and are depth rated up to 6,000 m

SPRINT-Navs integrate a Syrinx DVL, pressure sensor and inertial engine all-in-one; the ultimate vehicle navigator

Saves time. Saves cost. Saves payload space
