PURPOSE: A system and method for obtaining real time navigation data and evaluating performance are provided to perform performance evaluation of navigational data of a GPS(global positioning system) guided missile by calculating a DGPS(differential GPS) reference trajectory. CONSTITUTION: A GPS conduction kit(100) provides accurate location, speed, and posture to a GPS guided missile used in an air force plane. A mounted measuring device(210) mounts the GPS conduction kit in the GPS guided missile and transmits the accurate location, the speed, and the posture of the GPS guided missile to a measurement system(300) of a ground control room through a radio-tracking link for the whole playing section. A ground measurement system receives navigational data of the GPS guided missile with a DGPS reference station receiver through the radio-tracking link. The ground measurement system extracts a navigation system GRC(GPS Receiver Card) origin measurement value based on origin measurement value information of the DGPS reference station receiver using commercial DGPS processing software. The ground measurement system calculates a DGPS reference trajectory and performs performance evaluation of the GPS guided missile.
