Research on the Two-position Calibration Method for SIMU Errors before Launching

In this paper, the calibration method for SIMU Errors before launching was studied in theory. The dynamically tuned gyro SIMU was the main object of the research. On the basis of the characteristics of the tactical missile before launching, A two-position calibration method before launching was proposed. The method can sufficiently utilize informations of the missile before launching and properly select the calibrating positions to calibrate the main unsteady error parameters of SIMU. The theoretical analysis and experiment result show the new method can calibrate the main error parameters of SIMU before launching, therefore, it can improve the utilizable accuracy of SIMU and relax the stability of SIMU.
