Abstract:
PURPOSE: A performance verification apparatus of a GPS/INS-integrated navigation system is provided to simulate dynamic behaviors and management of a system and to check and control the navigation performance in real time by using a common GPS/INS simulator. CONSTITUTION: A performance verification apparatus of a GPS/INS-integrated navigation system includes a GPS/INS simulator(210) which generates inertia data which includes a GPS signal of a guided missile, information of the acceleration and angular velocity of the guided missile; an integrated navigation system check part(220) in which an INC[Integration Navigation Card] and a GRC[GPS Receiver Card] which are included in the GPS/INS-integrated navigation system are mounted and a simulated management of the guided missile by the INC is controlled; and a control unit(230) which monitors the simulated management of the guided missile and generates a control command in order to control the simulated management. In the GPS/INS-integrated navigation system, the GRC transmits GPS navigation information to the INC after the dropping of the guided missile and the INC performs the integrated navigation of the guided missile based on the GPS navigation information and the inertia data after the dropping of the guided missile.

Abstract:
PURPOSE: A GPS(global positioning system) and INS(inertial navigation system) integrated navigation system for loading a GPS guiding kit is provided to accurately strike a target by attaching the GPS guiding kit on a conventional bomb. CONSTITUTION: A telemetry transmission system(100) of a guided missile provides GPS and INS integrated navigation information including the posture, the speed and the position of the guided missile to the ground. A ground telemetry reception system(200) receives the GPS and INS integrated navigation information. A fight control unit(300) controls arrival and departure, flight direction, flight altitude and speed. A pilot display unit(400) communicates using a data transmission card embedded in the flight control device and a wireless data link.

Abstract:
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.

Abstract:
PURPOSE: A secondary battery charging apparatus and a system thereof are provided to secure the safety of a secondary battery and to interrupt charge of the secondary battery if an internal temperature of the secondary battery increases. CONSTITUTION: A temperature receiving unit(110) receives a temperature sensed from a temperature sensor(133). The temperature sensor is arranged inside a secondary battery. An interruption unit(120) interrupts charging current supplied from the secondary battery if the transmitted temperature is greater than a reference temperature. A display unit(130) displays the interrupt of the charging current.
