Abstract
This paper presents the results of the effort to develop a transfer alignment algorithm designed to align a low-cost Fiber Optic Gyroscope Inertial Measurement Unit(FOG-IMU) with the Position and Azimuth Determining System(PADS) of Guided Multiple Launch Rocket System(GMLRS) in a short time with high accuracy. The Ring Laser Gyroscope IMU(RLG-IMU) of the PADS is defined as the Master Inertial Navigation System(MINS) and the FOG-IMU as the Slave Inertial Navigation System(SINS). The accurate attitude initializing of SINS based on the attitude information of both INSs can be accomplished by providing the normal launch motion(pitch and yaw). The relevant state equations and measurement equations of transfer alignment Kalman Filter(KF) are presented. A particular calibrating scheme is designed to determinate the parameters of the MINS and SINS just in the same time. The algorithm is verified by laboratory testing of both INSs under the compound manoeuvre of a three-axis turntable modeling the launch procedure of GMLRS.
