THE TECHNOLOGY

Because GPS signals are not directly receivable under water, Navimate™ functions through use of a small unit that is most commonly hung from a dive boat or buoy (the “GPS gateway”).

The GPS gateway has a floating radio antenna in order to determine its exact location, and communicates with the wrist units via its underwater transducer portion, using acoustic signals. As a result of this communication, the wrist units know their range and bearing from the GPS gateway, as well as the exact position of the gateway.

This allows the wrist units to calculate their own absolute position, independent of the position or motion of the GPS gateway. The gateway or the boat to which it may be attached is free to drift without affecting the position displayed by Navimate™. The position is displayed on the Navimate™ screen both as latitude and longitude values as well as a “dot”.
