Underwater navigation, communications and surveillance for divers

Navigate safely underwater

 

UWIS is an underwater navigation, communications and surveillance system that utilises the triangulation principle.

With UWIS’s help the divers’ underwater location can be determined with just a few metres accuracy. It also enables communication between the dive participants and the surface via pre-set messages.

The dive data is relayed to the surface via a buoy and the dive leaders are able to use the UWIS-software to track the progress of the divers in real time. Recording of the data helps to analyse and plan the dive missions.

The system is able to track up to 100 divers simultaneously over an area of 1000 metres across an in depth of 150 metres.

UWIS – Underwater Information Systems

 

Locate, track, communicate

 

UWIS system consists of three buoys and a diver unit that is attached on the air tank. The system communicates underwater via ultrasound.

The diver unit is attached on the air tank and it communicates with the display wirelessly via Bluetooth, Wi-Fi or inductive data transfer. The communications between a diver unit and the master buoy are carried out via ultrasound.

Dimensions: 105 x 115 x 94 mm

The buoys are equipped with GPS sensors and they are connected via Wi-Fi. The divers’ location is tracked with ultrasound using triangulation principle.

Dimensions: Height 1,9 m deployed, 1,0 m stored

The UWIS application is browser based and compatible with both Windows and MacOs operating systems.

UWIS is versatile

 

UWIS is already more comprehensive than any other alternative system. The UWIS company updates the software, buoys and diver units constantly and new applications and devices are developed for the system in co-operation with world’s leading dive equipment manufacturers and diving organisations.

UWIS system features

Underwater location data

UWIS tracks divers’ absolute and relative location underwater with a couple of metres accuracy. The location is transmitted to the surface personnel and other divers via the master buoy.

Direction to the waypoint

UWIS tells the direction and distance of a dive buddy or planned waypoint. The browser-based application can track up to 100 divers simultaneously and records all dive data to be analysed or shared later.

Navigation with waypoints

UWIS enables planning of a dive by using pre-set waypoints and POIs (point of interest) to mark for example dive locations and ascension points. Using waypoints, the divers can proceed along pre-planned route underwater.

Setting waypoints

The system allows up to 100 pre-set POIs, which can be also be re-located form the surface during the dive. The diver’s display can be for example a dive computer, an underwater tablet or any other supported display unit.

Communication

UWIS revolutionises communication between divers and the surface. With it the group can communicate to each other and surface using up to 100 pre-set messages or alarms.

Alarms

UWIS has multiple alarms that can be set for example for depth, distance to dive buddy or dive master or ascension point. The alarms are automatic and they can be used according to the needs and wishes of the divers.

Monitoring the dive

UWIS allows monitoring of the dive from the surface. The application shows location of the divers and waypoints on a map and relays all messages and alarms.

Directing a group

UWIS allows the surface personnel to contact single divers or the whole group simultaneously. Dive leader can for example order them to surface, re-direct them to a new waypoint or alter the ascension point.
