Patent ID: 6995707

Claim:
A portable maritime scoring and simulation system, comprising: at least four buoys placed in a body of water; a global positioning satellite (GPS) receiver attached to each buoy to provide a GPS location of the buoys; an radio frequency (RF) radio system attached to said each buoy; an acoustic analysis system attached to said each buoy to capture an acoustic signature of ordnance impacting the water; a microprocessor attached to said each buoy, wherein the microprocessor monitors and controls the GPS receiver, the RF radio system, and the acoustic analysis system; a system controller to control and monitor the microprocessor; and, an RF radio repeater system linking the RF radio system with the system controller, wherein when the acoustic signature is captured by the acoustic analysis system, the RF radio system transmits a time of capture and the GPS location of said each buoy to the system controller through the RF radio repeater system, wherein when said at least four buoys transmit the acoustic signature, which is captured, the system controller computes a location of impact using a location process, and wherein the location process comprises a calculated accumulated error computed by summing residuals, each of said residuals is an output generated from a calculated impact location and said GPS location of said each buoy.
