UWIS

Underwater information systems · Finland

KNOW WHERE
YOU DIVE.

Underwater positioning, navigation and communication. Give your team a shared view of the dive, from the surface to the seabed.

For SAR teams, scientific and professional diving. For divers and ROVs.

Knowing a position is the starting point. What matters is how your team uses it.

01

See the operation

Monitor divers and ROVs from the surface, with location information updated in near real time.

02

Navigate with a plan

Use waypoints to support routes, searches and return points with a compatible underwater display.

03

Stay connected

Exchange predefined messages between divers and the surface. Record dive data for review after the operation.

WHO IT'S FOR / 01

Bring structure to the search.

Support systematic underwater searches with diver location information, planned waypoints and a shared view from the surface.

The priority: finding the search target and documenting the search.

Three UWIS Buoy Units

GNSS-equipped buoys establish the surface reference. Underwater positions are calculated using acoustic trilateration.

02 / UNDERWATER

UWIS Diver Units

Up to 100 UWIS Diver Units accompany divers or ROVs and communicate acoustically with the three buoys.

03 / SHARED VIEW

Above and below

UWIS Tracker (Windows) and UWIS Viewer (Android) serve the surface team. UWIS Navigator (Android) brings navigation and messaging to the diver on Alltab.

Connected wirelessly. Free to move. UWIS uses wireless underwater positioning and communication, giving divers freedom of movement and supporting safety through shared position information.
