A Rapid Alignment Technique Without S-Turn and Accelerometer

Min-I James Chang

Abstract:	For some missiles, the missile’s acceleration is not a necessary feedback element of the missile’s flight control system. Therefore, the 3 accelerometers may be replaced by a Doppler sensor to enhance the performance of the missile guidance, navigation and control system. In this paper, an integrated navigation that consists of a GPS, 3 gyros and a Doppler sensor (GPS/GYRO/DOP) is proposed for missile guidance, navigation and control (GNC). The benefits of the GPS/GYRO/DOP navigation system include rapid alignment capability, no S-turn requirement, anti-jamming capability and high navigation accuracy.
