Set value calibration manner null of the inertial standard device frame of reference in

摘要

PURPOSE: To provide a calibration method for a set value of each axis of coordinate system of an inertia reference device of a moving body in which setting of initial values of the coordinate system of the inertia reference device of the moving body can be omitted, and the method can be carried out without necessity of providing a new special means in the moving body. ;CONSTITUTION: The moved course Tr after beginning of flight of a moving body 16 is observed by measuring means 12, 20 provided on known points agaist the moving base point 14 of the moving body 16, Pso. The angle data of respective axes of the coordinate system of an inertia reference device 18 in a missile is obtained by the position Pm of the moving body 16 on reference navigation coordinates at observation from the observed orbit Tr of the moving body 16 on the reference navigation coordinate system, and the obtained angle data are input to the same inertia reference device 18 as set values concerning respective axes through a correspondence means, so as to renew the set values of the last time.;COPYRIGHT: (C)1994,JPO&Japio
