ABSTRACT:
A system and method for determining the geographic relationship between a surface station and at least one diver, including a first and second devices for sending passive or active select signal frequencies and receiving select signal response frequencies data. A third and fourth devices for receiving passive or active select signal frequencies data and sending passive or active select signal response frequencies to the first device. A fifth and sixth device for processing data based on a cycle time and a seventh and eighth device for plotting the data received from the fifth and sixth devices. The fifth and sixth devices includes a memory containing data structure for storing information relating to determining the geographic relationship between the first and second devices based on direction and cycle time, including fields which store select signal frequencies and select response signal frequencies, fields which store cycle data to determine distance and direction relationship data, and fields which store recall or alarm mode activation. A computer program product includes a computer storage medium having a computer program code mechanism embedded in the computer storage medium for causing a computer to initiate a mechanical alarm should the system be activated in the active recall or alarm modes. A computer program product includes a computer storage medium having a computer program code mechanism embedded in the computer storage medium including a code device for plotting and transmitting the data to the seventh and eighth devices.
