Scheme of Online Calibration of Main and Sub INS Based Rockets Rotary Motion
摘要
Abstract
For the preparation phase before the launch rocket can only be two degrees of freedom of angular movement but the line motion,and the need to calibrate many parameters,the model led to calibrate a large number of dimensions and poor real disadvantage. In this paper,the background of transformation guided rockets,first with the principle of rotation modulation error model is established,so that the zero-bias error inertial separation,and analysis of the rotation on the scale factor error,and the results show that the rotational motion on the scale factor error observability of significant influence. However,a separate roll motion can not motivate all six scale factor error,so the design of a new scheme of maneuver,and filtering algorithms rendering all scale factor error can be observed,and the results showed that in addition to x-axis gyro scale factor error,the remaining parameters can faster convergence. Compared with traditional methods,timeliness and accuracy of the calibration has been greatly enhanced, the importance of the rocket projectile roll motion on is fully embodied before the launch calibration.关键词
