PROBLEM TO BE SOLVED: To provide a position finding system and a position finding method that make possible acquisition of flight data of a gun shell in the early stage of its flight.;SOLUTION: In a position finding system 100, a GPS receiver 11 has a memory 11d that stores digital output signals T based on input signals generated from a plurality of satellite waves W, and an analyzer 40 has a controller 41 that, after executing search of carrier frequencies and code phases and synchronous tracking of carrier components and code phases while reproducing the digital output signals T, executes collection and position finding of pseudo ranges and navigation messages while reproducing the digital output signals T once again.;COPYRIGHT: (C)2014,JPO&INPIT
