Abstract

Systems and methods for tracking diver location in accordance with embodiments of the invention are disclosed. In one embodiment, a dive computer includes a processor, a pressure transducer connected to the processor, and clock circuitry connected to the processor, wherein the processor obtains water speed information using a flow measurement device that measures water speed when below water, measures a first piece of position information using a global position system receiver (GPS) that generates position information, generates depth and time information using the pressure transducer and the clock circuitry when the dive computer is below water, combines the first piece of position information, depth information, water speed information, and time information into a dive log, stores the dive log using a memory, and estimates a position of a diver using the first piece of position information, time, depth, and water speed information from the dive log when submerged.
