Ensuring Reliable Navigation for Tactical Divers

Diver navigation has long presented a challenge. Ensuring diver safety is crucial, and the consequences of not having reliable navigation and position information are far greater for missions using divers than ROVs or other uncrewed systems. UK-based Blueprint Subsea’s Artemis diver navigation systems are engineered to give operators confidence and control in such situations.Accurate positioning and dead-reckoning navigation capabilities are essential for maintaining situational awareness and keeping divers safe during long-duration underwater missions. Blueprint relies on Nortek’s DVL
