Abstract

The invention relates to a remote GPS based locator system for reporting an at-ocean torpedo for recovery. The system comprising of a remote tracking base station and on¬board dynamic positioning reporting terminal means which is coupled to two external sources such as Global Positioning System satellite and communication satellite. The system is capable of receiving a positioning signal transmitted from the Global Positioning System satellite and transmit the same to the remote tracking station. The on-board dynamic Positioning Reporting Terminal means further coupled to an transponder-antenna means to communicate with GPS satellite and Communication satellite systems. The system further includes an on-board water-pressure identification means for indicative of the approximate position of the torpedo below the water surface and on-board ejection means for eject and extend an antenna towards the ocean surface, when the pressure identification means identifies a water pressure level falling within a preselected range, thereby activating the antenna to communicate with GPS satellite and Communication satellite systems.
